Weekly Summary of AI topics

[Discourse]

Overview

This week’s AI-focused discussions on Meta Discourse centered on making AI features feel more “native” and reliable—both in UX and in admin operations.

On the product side, Discourse shipped background AI image captions that improve accessibility and discovery without polluting post raw content, plus confirmed synergy with AI Translate for localized captions (Making post images more accessible with Discourse AI, search indexing notes, translation workflow). Data teams also got a major boost with AI-generated Data Explorer SQL directly in the plugin UI (Data Explorer AI).

On the UX side, the docked composer for AI bot conversations continued to spark debate—especially the Enter-to-send behavior—leading to a community theme-component workaround and even a PR proposal for an admin toggle (Introducing a docked composer…, follow-up UX feedback, theme component fix, PR reference).

Operationally, there was practical troubleshooting around AI embeddings semantic search failing with a 500 due to mismatched embedding dimensions, resolved by recreating configuration with the correct dimension size (AI Embeddings Semantic Search returns 500 error, dimension mismatch log, solution). Meanwhile, AI Translate received improvements and fixes: an enhanced translation progress graph experience and a bug fix ensuring deleted content isn’t exposed/translated unnecessarily (AI Translation Progress Graph, Deleted posts still show full content…).

Interesting Topics

• Background AI image captions (accessibility + search) without altering post raw (#Announcements ai ai-image-caption)
  nat announced a rework where captions are generated in the background, stored separately, and surfaced in screen readers/search/lightboxes instead of being inserted into the post body (Making post images more accessible with Discourse AI). loginerror asked whether captions are crawlable, and nat clarified they render into HTML as aria-description and are included in Discourse search, though external crawler weighting varies (crawler Q, aria-description answer). The thread also highlighted translation synergy—captions can be localized and edited per language inside the translation composer (AI Translate synergy).

• Generate Data Explorer SQL with Discourse AI (and iteratively refine queries via prompt) (#Announcements data-explorer ai)
  Discourse shipped an AI helper inside Data Explorer so admins can either write SQL manually or have AI generate/modify queries on /new and /edit—with the preference remembered on-device (Data Explorer AI). The release also connected back to prior community requests for a smarter “SQL helper” experience (Empower the SQL helper).

• Docked AI-bot composer friction: Enter-to-send vs deliberate drafting (#Announcements composer ai ai-bot)
  In ongoing feedback, tobiaseigen described the docked composer as a “permanent change” that encourages accidental submission, preferring a slower/more deliberate UI for bot interactions (feedback). Others echoed frustration with Enter-to-send, especially when pasting multi-line troubleshooting content (more feedback, impact on longer replies). Workarounds like Shift+Enter were noted, but the usability debate continued (Shift+Enter suggestion, “no forgiveness” concern).

• Community fix: theme component to revert Enter behavior for AI-bot messages (plus PR discussion) (#Theme component composer ai ai-bot)
  To address Enter-to-send pain, Lilly published a theme component that restores “Enter = newline” for AI bot message submissions (not chat), requiring click/tap to send (Bot enter button fix for Discourse AI). They later updated it to work whether the docked composer is enabled or not (follow-up fix). In the docked-composer feedback thread, Lilly also linked a proposed PR to add an admin site setting toggle (theme component announcement in context, PR reference).

• Should Enter-to-send be site-wide admin setting or per-user preference? (#Announcements ai-bot composer)
  When Lilly leaned toward an admin-controlled toggle (admin toggle rationale), RGJ raised concerns about inconsistency across forums and argued a user preference may be better (preference vs site setting, cross-site inconsistency concern). Lilly noted a “proper” approach might be a broader user preference affecting more than just bot messages, but that it’s significantly more work (broader preference idea).

• Troubleshooting: AI Embeddings Semantic Search 500 error caused by embedding dimension mismatch (#Self-hosting search ai)
  akanora reported semantic search returning a 500 while standard search worked (error report). After Falco confirmed an embeddings model must be configured (model setup check), logs revealed the root cause: expected 768 dimensions, got 3072 for Gemini embeddings (log details). Recreating the embeddings config and setting dimensions to 3072 resolved it (solution), with nat emphasizing that the “Run test” validates credentials but not the full semantic search process (clarification).

• Custom sidebar links & sections can now be translated (content localization + dynaloc) (#Feature sidebar ai dynaloc content-localization)
  A long-running request to translate custom sidebar content was marked as completed, with nat pointing to the merged PR and sharing screenshots (completion update).

• AI Translate progress graph improvements (performance + clarity + content-type breakdown) (#Data & reporting translation ai)
  nat delivered a significant UI/UX update to the translation progress graph, including cached timing indicators and progress broken down by content type (topics/posts/etc.) (translation graph update). LotusJeff confirmed the update is “way more useful and self-explanatory,” while flagging a minor help-text mismatch for “Eligible” (feedback).

• Feature request: date picker for AI Translate “backfill after” settings (avoid topic/post mismatch) (#Feature ai dynaloc content-localization)
  Building on translation reporting improvements, LotusJeff requested a date-specific selector rather than “days in the past,” to keep topic/post translation windows aligned (request context). nat agreed and noted the UI used to display a running date, making the case for a clearer date-based setting (Request for a date picker…, agreement).

• Provider compatibility: DeepSeek Open Platform “no response” traced to incomplete OpenAI API support (Support ai)
  In a Chinese-language support thread, AkarinLiu concluded the DeepSeek official Open Platform’s OpenAI-compatible API was functionally incomplete, and resolved the issue by switching to Xiaomi’s MIMO V2.5 (diagnosis, solution).

Activity

• nat shipped and clarified multiple AI improvements: background image captions in #Announcements (Making post images more accessible with Discourse AI, search crawler details, AI Translate caption localization); AI-assisted SQL generation for data-explorer (Data Explorer AI); guidance on debugging semantic search by checking /logs (AI Embeddings Semantic Search returns 500 error); confirmation that sidebar links/sections can be translated now (Feature request: translate custom sidebar links); translation backfill/graph improvements and responding to date-picker feedback (AI Translation Progress Graph, follow-up date-picker discussion, Request for a date picker…); and a fix for deleted-post translation behavior (privacy + token savings) (Deleted posts still show full content…).

• Lilly drove the practical response to Enter-to-send UX issues by releasing a theme component workaround (Bot enter button fix for Discourse AI) and iterating it for docked composer on/off compatibility (follow-up fixes). They also proposed an admin-level toggle via PR and discussed tradeoffs between admin settings and user preferences in the docked-composer thread (enter behavior complaint + link-out, PR note, site-wide toggle stance, broader preference idea).

• loginerror focused on how AI-generated image captions affect SEO/discovery and pushed for future integration ideas with AI Translate (crawler question, Translate synergy question).

• tobiaseigen provided detailed UX feedback on the docked composer, emphasizing that bot conversations often benefit from a slower, draft-friendly workflow and calling out accidental submissions from Enter-to-send (Introducing a docked composer for AI bot conversations).

• Jagster suggested parity with chat’s “send shortcut” setting and raised practical mobile ergonomics questions—like how to use Shift+Enter on iPad (chat shortcut thought, iPad question in Ask Discourse thread).

• one1 reported real-world pain using Ask Discourse for troubleshooting now that the interaction model behaves more like chat (Enter submits), noting the lack of forgiveness when accidental submits happen (docked composer feedback, Ask Discourse complaint, long-form troubleshooting context).

• NateDhaliwal connected the Ask Discourse behavior change back to the docked composer rollout and reiterated the Shift+Enter newline behavior as a workaround (Ask Discourse reference, Shift+Enter reminder, cross-link back to docked composer).

• mcmcclur clarified that Shift+Enter still allows composing multi-line messages in Ask Discourse, while acknowledging it may not be ideal UX and responding to mobile usage concerns (Shift+Enter explanation, iPhone/iPad guidance).

• RGJ challenged the idea of an admin-only toggle for Enter behavior, warning that inconsistent settings across Discourse instances can be confusing, and questioned why bot interactions aren’t implemented as chat (preference question, consistency concern).

• akanora documented a full troubleshooting loop for semantic search failures, shared log output pinpointing embedding vector mismatch, and confirmed the resolution by recreating embeddings config with updated dimensions (issue report, logs showing mismatch, solution confirmation).

• Falco helped narrow down the embeddings semantic search issue early by verifying whether an embeddings model was configured at all (setup prompt).

• nathank celebrated the Data Explorer AI launch as a direct fulfillment of the earlier “Empower the SQL helper” request, linking the new announcement back to that feature desire (Empower the SQL helper, Data Explorer AI).

• HAWK added operational context in support discussions, noting the AI plugin’s role in illegal-content triage scanning on free sites (a difference from paid plan behavior) (Can’t get the AI plugin enabled).

• LotusJeff validated the improved translation progress graph and proposed a date-based translate-backfill setting to avoid mismatches between topic/post translation windows (AI Translation Progress Graph feedback, date-picker request follow-up).

• AkarinLiu closed the loop on provider troubleshooting by identifying incomplete OpenAI API compatibility in DeepSeek’s official platform and switching to another provider to restore responsiveness (DeepSeek thread diagnosis, DeepSeek thread solution).

Overview

AI-related discussion on Meta this week clustered around making Discourse AI outputs more reliable, more controllable, and less surprising.

On the quality front, sam kicked off a deeper look at improving report accuracy by layering validation workflows on top of the existing AI reporting pipeline (Improving accuracy of AI reporting through validation), building on earlier work like Discourse AI periodic summary reports, Meta’s own daily summary feedback, and the newer automation framework in Discourse workflows.

On the control and predictability side, translation behavior was a major theme: akanora reported Turkish translations becoming oddly archaic (Turkish translation is generating archaic/Ottoman-style language instead of modern Turkish), and Falco traced it to an overly “transformative” translator prompt—then shipped a fix (Falco’s fix details). That same change also connects to earlier concerns about translation “over-improving” the author’s tone (Language level of ai “translate to English”).

Finally, operational/admin concerns popped up: how to disable AI entirely (How do Disable AI), how to interpret “invalid JSON” structured output logs (Discourse AI: structured output response was not valid JSON), and requests for better cache/usage transparency in translation tooling (Allow clearing cache). Meanwhile, ongoing product polish continued via improvements to the docked composer UX for AI bot conversations (Introducing a docked composer for AI bot conversations), newly merged AI Translate settings UX (Request for a date picker in AI Translate settings), and broader ecosystem progress in the long-running chatbot plugin thread (Discourse Chatbot ).

---

Interesting Topics

• Validating AI reports with workflows (beyond “one-shot summarization”)
  sam outlined how Discourse AI reporting has historically been a simple pipeline—context → LLM → post—and proposed using workflows to add validation steps for higher accuracy (Improving accuracy of AI reporting through validation). The discussion explicitly ties into existing reporting features (Discourse AI periodic summary reports) and the public iteration loop via report critique threads (daily summary feedback).

• “Agent skills” as a scalable way to manage AI bot behavior
  sam proposed structuring reusable “skills” as topics to avoid bloated system prompts and enable progressive disclosure (Giving Discourse AI agent skills). mcwumbly shared hands-on experience splitting one large prompt into multiple skill topics, and asked about automatic skill discovery rather than manually listing them (skills follow-up). The approach leans on ai custom tooling patterns (AI bot custom tools).

• Turkish translations drifting into archaic/Ottoman-era language (and a prompt fix)
  akanora reported “Translate to Turkish” producing archaic phrasing like “Binaenaleyh” and “Velakin” (report). After clarifying this was the Edit menu translation tool (clarification), Falco adjusted the translator prompt to “keep to its lane” (fix explanation), and akanora confirmed it resolved the issue post-merge (confirmation).

• Translation “improver” behavior raising language level (related to the Turkish fix)
  Moin pointed out that the same change that fixed Turkish should also address translations unintentionally “beautifying” language and tone (Language level of ai “translate to English”). This provides historical context for why “faithful translation” matters and how prompt wording can create surprising output.

• Structured output logs: “not valid JSON” warnings, parsing edge cases, and what to do about them
  lilydjwg flagged log noise after an update: “structured output response was not valid JSON” despite valid-looking HTTP responses (initial report). Falco clarified it’s a warning and planned to downgrade it to INFO to reduce alarm (response), while lilydjwg argued it indicates a real bug in the escaping logic and suggested spec-aligned escaping boundaries (follow-up, example).

• Admin policy question: disabling AI cleanly
  JDParker asked how to disable AI due to company policy (question), and Lilly provided the admin path via installed plugins (solution). Straightforward, but notable as more orgs formalize AI usage guidelines.

• Requests for better transparency/control over translation caching
  darkpixlz asked for clearer translation-page dashboards and either shorter cache durations or a bypass mechanism (Allow clearing cache). This sits in the “ops ergonomics” bucket: understanding spend and seeing near-real-time changes.

• Docked composer UX polish: “send shortcut” setting wired into core
  In the AI bot docked composer thread, keegan announced an update moving “send shortcut” to a core user setting and reusing it for AI bot conversations (Introducing a docked composer for AI bot conversations). It’s a small UX tweak, but affects daily usability for anyone doing lots of AI chat in Discourse.

• AI Translate settings UX: date picker request merged
  nat confirmed a requested date picker enhancement for AI Translate settings was merged (Request for a date picker in AI Translate settings), reinforcing steady incremental improvement in content-localization tools.

• Chatbot plugin progress: reasoning strategies, gating, tools rename, and security hardening
  merefield posted a consolidated PR summary for early August work in the chatbot ecosystem, including new reasoning strategies, a semantic blocked-question gate, consolidation work, renaming “Function”→“Tool”, and swapping to a safer calculator evaluator (Discourse Chatbot , plus follow-up screenshot/context in the next post).

Activity

• sam drove two higher-level ai design conversations: one on adding workflow-based validation to improve summarization accuracy (Improving accuracy of AI reporting through validation, referencing Discourse AI periodic summary reports and daily summary feedback), and another on structuring reusable “agent skills” in-topic to reduce system prompt sprawl (Giving Discourse AI agent skills, building on AI bot custom tools and adjacent automation ideas in Discourse workflows).

• Falco handled multiple ai support/quality items: triaged the Turkish translation regression (Turkish translation is generating archaic/Ottoman-style language), confirmed the activation path with akanora (clarifying question, answer), then shipped a prompt adjustment to keep translations faithful (fix) with user verification afterward (confirmation). Falco also responded to structured output JSON warning concerns by noting it’s a warning and suggesting a log-level change to reduce anxiety (Discourse AI: structured output response was not valid JSON), and merged a community PR related to AI persona prompting (Add {username} as a template param in AI persona system prompts).

• akanora provided a clear reproduction and screenshots for a Turkish translation quality regression, including identifying it as the Edit menu translator (report, where it happens), and confirmed the fix after it landed (confirmed). This also connects to broader “translation should not rewrite tone” concerns (Language level of ai “translate to English”).

• Lilly answered an admin/policy support request by pointing to the plugin management path to disable AI (How do Disable AI), resolving the original question from JDParker (question).

• nat provided an update that the requested AI Translate settings date picker feature was merged (Request for a date picker in AI Translate settings), continuing the content-localization improvements.

• keegan updated the AI docked composer experience by moving the “send shortcut” preference into a core user setting and using it for AI bot conversations (Introducing a docked composer for AI bot conversations), which should reduce inconsistency between chat and AI composer interactions.

• merefield posted a dense, implementation-focused PR roundup in the chatbot plugin megathread, highlighting additions like verify-and-revise reasoning, semantic blocked-question gating, tool API cleanup, and calculator security improvements (Discourse Chatbot ; supporting follow-up in the next post).

• Moin connected the Turkish translator prompt fix to a long-standing complaint: translation that “improves” language level rather than translating faithfully (Language level of ai “translate to English”), pointing readers to the same underlying adjustment discussed in the Turkish bug thread (prompt fix referenced here).

• darkpixlz raised an ops-focused feature request around cache duration/bypass and better dashboard transparency for translations and token usage (Allow clearing cache), echoing a broader desire to make AI cost/behavior more observable (related in spirit to report quality discussions like Improving accuracy of AI reporting through validation and the established reporting feature set in Discourse AI periodic summary reports).

• lilydjwg dug into structured-output parsing behavior and found a likely culprit: line-feed escaping that turns otherwise valid JSON into invalid sequences, along with a suggested spec-aligned fix approach (Discourse AI: structured output response was not valid JSON, technical rebuttal, minimal example). The exchange with Falco captures the tension between reducing noise and fixing root cause (Falco reply).

• mcwumbly shared practical experience applying the “skills as topics” approach—splitting a single agent prompt into multiple skill topics—and asked about automatic discovery/indirection to avoid manually enumerating skills in the system prompt (Giving Discourse AI agent skills). This directly supports the direction sam laid out (original proposal) and sits alongside tooling enablers like AI bot custom tools.

• 42aross followed up on the community-contributed feature to add {username} as a template parameter in AI persona system prompts, and celebrated after Falco merged it (follow-up, merge confirmation, thank-you). This kind of small templating capability can improve personalization and reduce brittle prompt duplication across personas.

• JDParker surfaced a common admin requirement—disabling AI for policy compliance—which was solved quickly via plugin settings (How do Disable AI, solution).

Weekly AI Summary: meta.discourse.org

Overview

This was a substantial week for the Discourse AI ecosystem, with 49 new posts across 7 new topics, heavily weighted toward the AI plugin and its expanding capabilities. The week’s discussions coalesced around three primary themes: expanding AI features with the rollout of the Gemini Interactions API and native tools like code execution and Google Maps; tuning and constraining AI agents for specific community use cases, from gamification automation to scope-restricted forum assistants; and fixing quality and reliability issues, including structured output JSON validation, AI summary user attribution, and localization of translated content.

A recurring thread was the need for clearer guardrails and documentation. Several users—both newcomers and veterans—asked how to configure Discourse AI for their own needs, from adding unsupported languages to the language selector, to restricting bots from consuming LLM credits on arbitrary queries, to understanding model selection on agents. The team responded with both fixes and advice, including new PRs and clarifications on how the Workflows plugin can replace older Automation-based orchestration.

Interesting Topics

• Gemini Interactions API support lands in Discourse AI: sam announced that Discourse AI now supports Google’s new Gemini Interactions API, recommending it for all Gemini inference going forward. The existing generateContent API remains available but is relabeled as “Google Gemini (Legacy API)”. The new provider adds three native features: tool call streaming, code execution, and Google Maps tools, in addition to the existing Search and Fetch tools. A noted caveat is that the interactions API no longer permits disabling “thinking” on 2.5 Flash models, which sam flagged as unadvisable anyway for reasoning models.

• Adding unsupported languages to the Language Selector: Karthik_K1 asked how to add Indian languages (Hindi, Telugu, Tamil, Kannada, Malayalam) to the content localization language selector, given that AI can translate between virtually any languages. nat clarified that the selector changes the user’s entire Discourse locale—interface and content—and is limited by design to locales supported by Discourse’s i18n system with proper pluralization and fallbacks. He suggested either a plugin to register additional locales or contributing translations via Crowdin, with Moin recommending the plugin as a short-term solution.

• Automating gamification points via Workflows: satonotdead asked how to automate gamification points for “Quests” and tasks, rather than awarding them manually as a solo builder. awesomerobot suggested adding an “award cheers” action to the Workflows plugin, enabling a check post → wait for chat approval → award points pipeline. Falco linked to a PR implementing this feature, while Andrew_Rowe pointed to custom forms and the Custom Wizard plugin as alternatives.

• Restricting AI agents to forum-specific questions: Karthik_K1 asked how to prevent his AI agent from answering unrelated questions like “Who owns Uber?”, which consumes LLM credits. NateDhaliwal suggested the Forum Helper or Forum Researcher agents, but Karthik verified these also answer out-of-scope queries. Falco explained that the “Creative” agent has no system prompt, and recommended crafting a new agent with a system prompt specifying when to answer—the same approach used on ask.discourse.com, as noted by Ed_S.

• Built-in chatbot or conversational assistant?: Soumya_Ranjan_Mishra asked about built-in chatbot functionality beyond Discobot. RGJ pointed to the AI Bot documentation and @merefield’s Chatbot plugin. awesomerobot noted that Discourse AI covers all requested features out of the box—answering via chat or PM, auto-categorizing, and auto-tagging—and can power a dedicated page like ask.discourse.com via the Discourse AI documentation.

• AI summaries cite users as “User1”, “User2”: sk-or-v1-contents filed a bug report showing that AI topic summaries (used by CDCK/MoM) cite posts as “User1”, “User3”, etc., rather than actual handles, and also hallucinate content not present in the source posts. Falco confirmed this was handled by PR #42445, and noted the summary on the reported topic already looks better.

• Structured output responses fail JSON validation: lilydjwg reported that structured output responses from a local llama-server (Qwen3-4B GGUF) were rejected as invalid JSON, despite being schema-valid at the source. sam initially suggested a more capable model, but after lilydjwg proved the issue was whitespace/line-break escaping introduced by Discourse, sam acknowledged it as a legitimate bug and shipped PR #42339 as a fix.

• Docked composer preference discoverability: In the ongoing docked composer for AI bot conversations announcement, Moin asked where the chat-style composer preference is toggled on ask.discourse.com without manually entering /my/preferences/interface. keegan showed it lives under Fonts & Appearance, which Moin found unintuitive since “it isn’t about appearance.” martin suggested renaming the section to “Interface settings” for clarity.

• Translated category descriptions not auto-updating: Moin noted in Automatically update translated category descriptions that AI-translated descriptions of #contribute:ux and #contribute:feature categories remained stale for German users, even after English edits. nat confirmed a fix landed in PR #42407.

• Model confusion in AI agent chats: satonotdead asked how to update models on LLM agents, seeing a different model than expected when chatting. Falco explained that the “info” icon in AI chats shows the default title-setting request, which causes confusion, and submitted PR #42326 to improve this UX. The original confusion was a misunderstanding, not a bug.

• Content Localization documentation refresh: nat posted a batch of updates to the Content Localization - Manual and Automatic with Discourse AI documentation, including a new query for where users are coming from, links to multi-language preferences, custom sidebar link translations, an improved AI translation progress graph, and updated date picker settings documentation.

Activity

• Falco was the week’s most active contributor, earning 16 likes across 7 posts. He confirmed the gamification “award cheers” PR in the Automating gamification points discussion, provided guidance on crafting a system prompt in the AI agent scope restriction topic, demystified model display behavior in How to update models on LLM agents, and shipped PR #42445 to fix AI summary user attribution in the CDCK/MoM quality issue report.

• sam announced the new Gemini Interactions API support in Discourse AI, recommended against older 4B models in the structured output JSON thread, acknowledged the whitespace-escaping bug and shipped PR #42339, and participated in the {username} system prompt template discussion, warning about system prompt thrashing in multi-user chains and noting that vLLM templates were discarding the username—a patch was in progress.

• nat clarified the i18n limitation in the Language Selector discussion, linking to the how to add a new language and Add Uyghur language threads, confirmed the translated category description fix in the Automatically update translated category descriptions topic, and posted extensive documentation updates to the Content Localization guide.

• Moin asked clarifying questions about the docked composer preference placement, recommended a plugin-based approach for the Language Selector with a Crowdin contribution path, and reported the stale German translations in the category description issue.

• awesomerobot proposed the “award cheers” Workflows action in the gamification discussion and laid out how Discourse AI’s out-of-box features handle chatbot-style support with chat/PM integration, auto-categorization, and auto-tagging.

• satonotdead explored gamification automation and clarified the agent model update confusion, expressing enthusiasm for the upcoming Workflows plugin.

• Karthik_K1 raised the Language Selector question and presented the AI agent scope restriction use case with detailed flow diagrams.

• Lilly documented the Bot enter button fix deprecation, noting the underlying behavior is now controlled by a user preference from the docked composer feature, and shared a detailed Gemini API key setup guide in the Set up Gemini API Keys topic.

• keegan helped Moin locate the chat-style composer preference under “Fonts & Appearance” in the docked composer topic.

• RGJ recommended both the official AI Bot, the third-party Chatbot plugin, and an external LLM-backed service in the built-in chatbot question.

• per1234 revisited the AI + Automation Governance thread, describing how the new Workflows plugin solves orchestration pain points previously handled by the Automation plugin, particularly the redundant flags generated when custom Automation scripts overlapped with the AI Spam detector.

• lilydjwg provided detailed debugging—including tcpdump captures and Rails console checks—for the structured output JSON validation bug, proving the issue was whitespace escaping and helping sam ship a fix quickly.

• sk-or-v1-contents filed two detailed reports on AI summary quality, including user attribution failures and hallucinated phrases in summaries of unrelated topics.

• Ed_S demonstrated how ask.discourse.com politely declines out-of-scope questions, and martin proposed better naming for the composer preference location in the docked composer discussion.

• NateDhaliwal suggested using Forum Researcher/Forum Helper agents and custom system prompts for the AI agent scope issue.

This is clearly a degenerate loop. I need to stop. The generator must produce coherent text. I’ll restart with the actual task.## Overview

This week saw a mix of announcements, bug fixes, and community feedback in the world of Discourse AI. The headline was sam landing Discourse AI subagents, a significant new capability that allows decomposing agents into smaller, specialised pieces. There was also the release of delegated vision, enabling text-only models like DeepSeek v4 Flash to benefit from vision capabilities.

On the support side, rinion reported a persistent and annoying issue with the Discourse Helper Bot auto-opening in a private chat channel even with AI features disabled, which gabriel eventually fixed after some back-and-forth. Community members satonotdead and Moin separately flagged the Proofread helper stripping line breaks and breaking quotes, with a fix quickly landing from Falco. Discussions also surfaced around restricting AI agents to forum-specific topics, with Ed_S and Karthik_K1 sharing insights on the limits of prompt-based guardrails. Finally, the move of AI title suggestions into the composer helper drew useful UX feedback from the community, highlighting friction in discoverability.

Interesting Topics

• Discourse AI subagents — sam announced the landing of subagent support in Discourse AI. Subagents allow delegation of work from a main agent to specialised agents, which helps decompose agents into saner pieces, mix and match language models, protect against context bloat, and increase concurrency and speed. Examples include a Web Researcher subagent and a Fact validation subagent. More details on AI Agents are available in the AI Bot Agents topic.

• Delegated vision for text only models in Discourse AI — sam also shared the release of support for delegated vision, which enables text-only models such as DeepSeek v4 Flash to use the full feature set of Discourse AI by delegating vision to a vision-capable model like Qwen or Gemma. A new option now exists under the LLM configuration, and more details can be found on the LLM settings page.

• AI bot keeps auto-adding me to a private chat channel even though disabled? — rinion reported the Discourse Helper Bot persistently appearing as an open DM chat on every page load, despite AI features being disabled. gabriel acknowledged the issue and noted it was not the expected experience, then implemented a fix. After some troubleshooting and a manual channel removal by gabriel, the issue was resolved for rinion. Moin clarified how forum deployments work for non-Enterprise plans.

• Proofread helper strips lines on Meta — satonotdead reported that the Proofread helper strips all line breaks, turning content into big paragraphs and even breaking quotes and images. Moin confirmed the same behaviour with examples. Falco quickly responded that a fix was coming and the topic was marked as solved.

• AI title suggestions move to composer helper — chapoi announced that AI title suggestions have moved to the AI composer menu alongside other helpers. jaroslav.kovar provided feedback that since AI suggestions for categories and tags moved, no one seems to be using them, describing the new interaction as user-unfriendly. satonotdead echoed that aesthetics may have been prioritised over functionality, and asked if reversing the change or adding an option is possible. Jagster also asked how an ordinary user would know where to find AI suggestions.

• How can I restrict an AI Agent to answer only questions related to my forum? — Karthik_K1 noted that prompts aren’t always reliable, having managed to trick the agent at ask.discourse.com into answering off-topic questions. Ed_S observed that 100% enforcement would cause more inconvenience than benefit, while Falco suggested practical approaches such as using Workflows to add a 2-pass evaluation or deploying fine-tuned models trained for the desired behaviour, as Discourse AI allows picking and choosing LLMs per agent.

• Configuring Discourse AI with internal OpenAI APIs — Soumya_Ranjan_Mishra asked about configuring Discourse AI with an enterprise/internal OpenAI-compatible API endpoint. Falco advised picking openai as the provider and configuring the URL, but Soumya_Ranjan_Mishra experienced errors. kddkd provided detailed configuration steps in Chinese, including entering the model service URL and API key, and noted that URL formatting could be the issue.

• Feedback for Ask Discourse — twofoursixeight provided feedback that links like “All Questions”, “topics”, “my posts”, “categories”, and “filter” are useless on the Ask Discourse site, as they navigate to empty pages for most members. HAWK asked how they accessed those pages since the site defaults to the AI bot, and twofoursixeight demonstrated via screen recording that the sidebar doesn’t always default to the AI bot one, especially in user settings.

• Giving Discourse AI agent skills — In the #Extras category, satonotdead asked if there is a beginner-friendly path into building skills for Discourse AI agents, noting their own technical limitations. sam acknowledged the complexity and mentioned that the AI team is thinking about introducing a new top-level concept for the “skill” use case, possibly around “grounding content” via categories, tags, or remote collections of data.

• Allow clearing cache — darkpixlz requested the ability to clear the cache or get more real-time updates on progress. awesomerobot explained the cache lookup is expensive, checking all posts back to the backfill date multiplied by languages and content types, and noted that even with a button, rate limiting would be needed. darkpixlz clarified they just want confirmation that things are processing and proposed storing the queue locally for more real-time updates.

Overview

Between 17 August and 24 August 2026, the ai area of meta.discourse.org saw 29 new posts and 4 new topics. The headline was the release of Detailed admin AI logs, a new admin-only diagnostic tool from sam. In Feedback for Ask Discourse, a temporary upgrade-related regression was reported and then resolved, sparking a useful side discussion about hidden link preferences. Troubleshooting continued in Configuring Discourse AI with internal OpenAI APIs, where the community shared environment variable and context-window tips. satonotdead opened several new feature requests around chat titles, per-group model selection, and monitoring agent chats. Finally, sam triaged a batch of older ai bug reports, closing several and confirming fixes in source.

Interesting Topics

• Detailed admin AI logs — sam announced a new admin-only log viewer at /admin/plugins/discourse-ai/ai-logs, with configurable retention, streaming response decoding, and rich filtering. nickdb called it a great feature, saying he had already been using it to track automatic translation, and suggested adding an auto-refresh option. Sam also linked back to the main Discourse AI topic for background.

• Feedback for Ask Discourse — Ed_S reported that Ask had started “spouting nonsense,” including a garbled response transcript. sam apologised, saying the team was upgrading. After replaying a conversation, Ed_S confirmed the LLM no longer lost the plot, though it emitted one piece of bad markup. A follow-up request to open links in a new tab led Falco to say it should respect the user preference, Moin to point out that the preference was hidden, and Ed_S to confirm it was finally visible.

• Configuring Discourse AI with internal OpenAI APIs — Soumya_Ranjan_Mishra hit errors while setting up an internal OpenAI-compatible endpoint. Moin asked whether there was a more detailed error in the forum logs, and satonotdead suggested setting DISCOURSE_ALLOWED_INTERNAL_HOSTS when using an internal IP. After a stack trace appeared with trim_messages, singi2016cn recommended adjusting the Context window to values such as 128000 or 200000.

• AI title suggestions move to composer helper — chapoi responded to UX feedback by explaining why the old star icon was “noisy” and “costly,” relying on a plugin outlet that often required absolute positioning. Consolidating AI actions into one predictable menu, he argued, is what makes the next set of features possible. He also teased a future where “users do not need to click anything at all.”

• Renaming chat titles on Discourse AI conversations — satonotdead proposed a feature to let users rename AI chatbot conversations through the UI, matching common LLM chat standards. He noted that automatic titles are good but not enough for users with their own naming or follow-up workflow.

• Conversational AI Search coming to Discourse AI — satonotdead asked why conversational AI search was not working despite having the agent enabled and no errors in the logs. nat asked for clarification on what “does not work” meant, while nickdb shared that his instance seemed determined to only answer questions about Discourse.

• Chosing different models for different groups/tiers — satonotdead asked whether a single agent could route different models to different groups, for example preserving expensive tokens for TL2/TL3 while using a cheaper model for TL1 users.

• About monitoring agents chats — Continuing from Discourse AI - AI bot, satonotdead asked how administrators and moderators can monitor AI bot chats without impersonating the agent. He explained that new users in his community use chat rather than PMs, so staff need a lightweight way to review conversations.

• Older AI bug triage — sam swept through a number of older bug reports this week. He asked martin whether to close Discourse AI does not respect the “everyone” group, marked Falsche Übersetzung, wenn post locale = UI locale as resolved, said Model name not showing in AI bot was long since resolved, confirmed the AI semantic search translation is now good, checked that the share conversation button in subfolder setups is fixed in source, and asked for more detail on the InputEvent message issue.

Activity

Here is how the community contributed over the last 7 days:

• sam shipped Detailed admin AI logs, apologised for the Ask Discourse upgrade interruption, and tagged Falco on the bad markup report. He also triaged Discourse AI does not respect the “everyone” group, Falsche Übersetzung, wenn post locale = UI locale, Model name not showing in AI bot, AI语义搜索时出现 missing count value 字样, Button to share conversation in AI conversation not respecting sub folder setup, and After sending the image, add this to the beginning of the message: [object InputEvent].

• Ed_S reported the Ask Discourse regression, confirmed the replay was fixed, requested new-tab links, and confirmed the preference is now available.

• Moin asked for detailed logs in Configuring Discourse AI with internal OpenAI APIs and noted in Feedback for Ask Discourse that most user preferences are hidden.

• chapoi shared the design rationale behind AI title suggestions move to composer helper, explaining the maintenance cost of the old star button and the path towards a no-click AI experience.

• satonotdead opened Renaming chat titles on Discourse AI conversations, Chosing different models for different groups/tiers, and About monitoring agents chats. He also asked for help with Conversational AI Search coming to Discourse AI and recommended the DISCOURSE_ALLOWED_INTERNAL_HOSTS fix in Configuring Discourse AI with internal OpenAI APIs.

• Falco weighed in on Feedback for Ask Discourse, saying external link behaviour should respect the user’s “Open all external links in a new tab” preference.

• nickdb praised Detailed admin AI logs and suggested an auto-refresh option. He also shared his early experience with Conversational AI Search coming to Discourse AI, which kept trying to answer only Discourse-related questions.

Overview

The week of August 24–31, 2026 on meta.discourse.org was dominated by a major ai announcement, a flurry of AI summarization bug reports, and notable plugin development activity. sam kicked off the week by unveiling the next version of Discourse MCP in #Announcements — a significant leap from 25 to 131 tools, introducing the new “toolsets” concept. Alongside that, several users surfaced issues around the AI summarization plugin: darkpixlz noticed topic summaries being cut short, while lilydjwg dug into a strange bug where extra spaces were being inserted into words sent to the LLM, even tracing it to a truncate call in the FoldContent class. satonotdead raised two separate concerns: the absence of AI summaries on the Horizon theme and a navigation dead-end between full-screen chat and the chatbot on mobile. On the development front, martin submitted a PR fixing the longstanding bug where Discourse AI ignores the “everyone” group, and merefield posted a major Discourse Chatbot 3.0.0 expansion adding Anthropic, Google Gemini, and xAI support. Overall, it was a week of rapid iteration, with strong community participation in testing, bug-hunting, and clarifying expected ai behavior.

Interesting Topics

• Discourse MCP the next version — sam announced version 0.3 of the Discourse MCP server, a massive upgrade from the 25 tools in 0.2.9 to 131 tools. The release introduces a new “toolsets” concept: by default, only a limited set of tools is exposed, but specifying toolset=all unlocks everything — from workflow generation and administration to AI configuration, analytics, and theme creation. fuse asked in the spirit of genuine learning what some use cases for a Discourse MCP server are, and Falco pointed back to the original announcement video for examples.

• Topic summaries being cut short — darkpixlz noticed that the automatically generated topic summary for their theme was truncated mid-sentence. Unsure whether it was an LLM or plugin issue, they suggested it would be cool if users could flag a summary or request regeneration. Falco promptly stepped in and regenerated the summary.

• Topic summarization sends to LLM with messages with extra spaces inside words or links — lilydjwg reported a curious bug after enabling AI summarization on their own site: the output contained invalid links like [keyd](https://man.arch linux.org/...) with spaces interpolated inside words (e.g. e nter, Ct rl, host s). Upon checking the AI logs, they discovered extra spaces throughout the request, even inserted between Chinese characters. In a follow-up post, they self-diagnosed the issue, attributing it to the truncate call in the FoldContent class.

• No AI summaries on Horizon? — satonotdead wondered why the Horizon theme, both on meta and their self-hosted instance, does not display AI summaries in the topic list. chapoi explained that this is expected behavior: AI summaries work via outlets, and Horizon has an opinionated design that deliberately doesn’t use any.

• Discourse AI does not respect the “everyone” group — This long-running bug was revived when martin posted a small PR to fix the issue, also addressing the buggy check return false if (SiteSetting.ai_bot_allowed_groups_map & post.user.group_ids).blank? — a welcome step toward making the AI bot’s group permissions behave as documented.

• No turning back on chatbot + chats — satonotdead reported a navigation dead-end in #Bug: when entering full-screen chat and then the chatbot (or vice versa), both back buttons spin in place, trapping the user with no way to return to the forum. awesomerobot asked for exact reproduction steps, and satonotdead clarified the sequence, noting they use the F Nav theme component for mobile navigation, though the bug should be reachable by URL regardless.

• Discourse Chatbot — merefield announced a major expansion of the Discourse Chatbot plugin in #Plugin: a PR adding first-class support for Anthropic, Google Gemini, and xAI alongside the existing OpenAI integration. The 3.0.0 version introduces provider-aware credentials and model selection, independent providers for LLM replies, embeddings, vision, and image generation, while retaining support for custom models and URLs (Azure, Ollama, proxies). Feedback was encouraged as the new provider support is slightly experimental.

• Discourse AI - Spam detection — In this #Site Management thread, The_Chromer asked whether it’s possible to tell if a user is a spammer based on their username — continuing the ongoing community discussion about moderation and how to leverage Discourse AI for spam detection effectively.

Activity

• sam published the week’s headline announcement of Discourse MCP 0.3, detailing the jump to 131 tools and the new toolsets system, and invited the community to share feedback under the mcp tag.

• Falco was highly active: they answered fuse’s question about MCP use cases by linking to the original MCP announcement video, and quickly regenerated the truncated topic summary reported by darkpixlz in their cut-short summaries report.

• satonotdead raised two issues this week: they asked about the missing AI summaries on Horizon and reported the chatbot navigation dead-end. They also followed up by providing detailed reproduction steps based on the F Nav theme component.

• lilydjwg reported the extra spaces bug in AI summarization requests, then followed up with their own diagnosis of the truncate call in FoldContent.

• darkpixlz flagged the topic summary truncation issue, pointing to the affected theme topic summary on meta and suggesting a flag/regenerate feature for AI summaries.

• martin contributed a PR fixing the “everyone” group permissions bug in the Discourse AI plugin, addressing both the permission mismatch and the faulty check.

• fuse engaged in the Discourse MCP announcement thread, asking for practical use cases for an MCP server.

• awesomerobot responded to the chatbot navigation bug report, asking for reproduction steps and whether the chatbot path was /discourse-ai/ai-bot/conversations.

• merefield posted the Discourse Chatbot 3.0.0 PR, expanding provider support to Anthropic, Google Gemini, and xAI within the existing OpenAI integration.

• chapoi clarified in the Horizon AI summaries thread that the missing summaries are by design, since Horizon avoids AI summary outlets.

• The_Chromer joined the long-running spam detection discussion, asking whether usernames can be used to identify spammers.

Weekly AI Activity Summary: meta.discourse.org

Week of August 31 – September 7, 2026

Overview

This was a busy week for AI on meta.discourse.org, driven by two major announcements, a flurry of Gemini-related bug reports after the 2026.8.0 release, and several thoughtful feature requests from community members.

The headline was nat's announcement of Ask AI, a new natural-language search experience that works side-by-side with indexed search, supports follow-up questions, and prompts users to create a topic when no good results are found. The feature drew immediate questions about token costs and a wave of detailed UX feedback from EricGT around prompt input sizing, sortable result columns, and the discoverability of the AI Bot fallback. Shortly after, sam announced that Discourse will ship a default llms.txt for all sites, with a conservative, token-efficient set of instructions for AI crawlers. rishabh also introduced the upgraded Discourse Admin Assistant, which can now take real moderation and configuration actions from chat with an approve/cancel flow.

On the troubleshooting side, RBoy reported that AI search and Disco Bot break with Gemini after updating to 2026.8.0, and filed a related Gemini Flash Lite thinking regression — sparking a broader debate about the maintenance burden of rapidly-churning LLM model IDs and legacy API support. Karthik_K1 worked through two self-hosting issues: blank Ask AI responses, which turned out to be a theme-related rendering bug, and Gemini API key errors, which he resolved with a LiteLLM workaround after help from Lilly and satonotdead.

Older feature discussions were also revived, including the AI search one-click experiment and Conversational AI Search coming to Discourse AI, while satonotdead filed two new requests for custom helper prompts and richer AI conversation management. Overall, the week highlighted both the platform’s accelerating AI investment and the growing pains self-hosters face keeping up with LLM provider changes.

Interesting Topics

• Ask AI launches for community search. nat announced Ask AI in #announcements, describing how it supports natural-language queries, follow-up questions, and a “Create topic” call-to-action when no results are found. jaroslav.kovar asked about additional token costs, and nat pointed him to the AI usage dashboard. satonotdead discovered the AI ask AI related count admin setting for controlling result boxes, which nat confirmed is a maximum, not a target. EricGT shared extensive feedback from a large hosted forum: he asked for a larger prompt input field and sortable result columns, suggested making the transition to AI Bot more discoverable with something like a “Continue in AI Bot” link, and proposed a tooltip or “Ask AI” button label to avoid confusion. nat responded that a full-page AI Bot conversation is the better fit for very long prompts, and that sorting improvements “can be considered.” Later, EricGT tried using Ask AI to find closely related GitHub issues from within a topic; Moin clarified that “This topic” scope is classic search behavior, not Ask AI.

• Automatic llms.txt is coming to all Discourse sites. sam announced that Discourse will ship a default llms.txt for every site, containing instructions for AI agents: do not impersonate people, do not auto-create accounts, respect robots.txt and rate limits, and prefer the Discourse MCP server when available. Ed_S asked whether self-hosters can customize or opt out; sam recommended a “Robots not welcome” file for sites that want to block AI entirely and stressed that the content is fully customisable. Ed_S also suggested a brief plain-text summary of forum purpose over linking to the About page; sam defended the template’s token efficiency and pointed out that most LLMs already know an outdated “picture” of Discourse, so the file helps them catch up on newer features like the Discourse MCP server. jaroslav.kovar asked how to inspect and adapt the file.

• Introducing the Discourse Admin Assistant. rishabh announced the rebranded and upgraded Discourse Admin Assistant (formerly the Discourse Helper Bot) for hosted sites. It can now answer questions by searching Meta, change site settings with an approve/cancel confirmation, help with moderation tasks (silencing users, locking topics, reviewing the queue), and answer questions about the site’s hosting plan and billing — all directly from chat.

• Gemini breakage and legacy API concerns after 2026.8.0. RBoy reported that Disco Bot / AI search throws errors with Gemini Flash Latest (3.7) after upgrading, with the log showing Role 'function' is not supported from the Gemini API. sam suggested switching to the non-legacy interaction endpoints; RBoy found those don’t accept -latest model aliases, which he argued creates significant administrative overhead as Gemini deprecates versions quickly. In a related thread, RBoy reported a Gemini Flash Lite thinking regression where enabling thinking throws a 400 error unless the thinking token budget is hardcoded, and noted the Pro model is “completely broken” after the upgrade. sam again pointed to the newer gemini-3.5-flash-lite endpoints, while RBoy pushed back on the cadence of required changes, arguing that Discourse admins can’t keep up with LLM churn and that TCO matters more than always having the latest model.

• Blank Ask AI responses traced to theme rendering. Karthik_K1 reported that Ask AI generated a response title but a blank answer body after switching his default LLM. nat initially suspected a 15.5-second response timing out past the 20-second deadline, but Karthik_K1's testing showed the problem only occurred on desktop, in two browsers. nat suggested safe mode, full-page Ask AI, and console/network debugging; Karthik_K1 ultimately found that themes were the culprit — the Mint theme only showed answers after scrolling, while the Foundation theme worked normally.

• Solving Gemini API key errors in Discourse. Karthik_K1 hit authentication errors connecting Google Cloud Vertex AI to Discourse AI, despite following the existing guides. Lilly walked him through a working Gemini API configuration (using the Gemini API service rather than Vertex), which Karthik noted wouldn’t consume his GCP credits. satonotdead recommended a LiteLLM proxy approach with token rotation, which worked well; Karthik_K1 confirmed switching to a lighter model eliminated latency and closed the topic as solved.

• AI search button missing after 2026.8.0. RBoy revived the older New Experiment: Enable AI search with one click! topic (originally from 2024) to report that the AI results button no longer appears in search results by default in 2026.8.0 — only after manually opening the advanced search filters. NateDhaliwal asked whether he meant the functionality in the Discourse AI AI Search guide, and pointed to Ask AI as a similar-but-different successor feature.

• Conversational AI search setup clarified. In the long-running Conversational AI Search coming to Discourse AI #feature topic, satonotdead clarified that his agent previously “didn’t show up at all,” nor did the user settings toggles. He determined the feature depends on both the agent configuration in Discover and the default base model, and confirmed it was “already resolved in Ask AI.”

• Custom helper prompts requested. satonotdead opened a Support thread asking how to add custom helper prompts to the Discourse Helper. He described working agents via the AI Bot that can develop a post from a pasted link, but noted the workflow of converting a PM into a topic and adding tags is laborious — he wants those capabilities exposed through the helper without re-entering the initial prompt each time.

• AI conversation management features requested. satonotdead filed a #feature request for Add groups, rename and remove to AI Conversations, covering the standard chat-UX features missing from the AI conversation panel (the same one used on ask.discourse.com): renaming chats, generating and organizing groups by agent/function, and deleting chats from the sidebar three-dot menu rather than inside each conversation. He noted this would improve information retrieval in the growing chat list.

Activity

• nat had a standout week, launching Ask AI and engaging at length with feedback. He confirmed token cost implications and usage monitoring, explained the “max count” behavior of related topics, responded to EricGT's UX suggestions, and pointed him to the AI Bot conversations feature. He also helped Karthik_K1 debug the blank Ask AI response, eventually guiding him through safe-mode and browser console checks.

• sam announced the default llms.txt rollout and robustly defended the template’s design in discussion with Ed_S. He also helped troubleshoot the Gemini AI search failure, advised switching to non-legacy endpoints, and made the case for staying on supported Discourse versions for security in the upgrade maintenance debate.

• rishabh announced the Discourse Admin Assistant, highlighting its new action-taking capabilities in chat, from site settings changes to moderation tasks and plan/billing awareness.

• jaroslav.kovar asked about Ask AI pricing and whether sites can check and adapt their llms.txt.

• satonotdead shared positive feedback on Ask AI plus the admin setting for related-count boxes, clarified the requirements for conversational AI search, filed requests for custom helper prompts and AI conversation management, and recommended the LiteLLM proxy approach for Karthik’s Vertex/credits problem.

• EricGT provided the week’s deepest product feedback on Ask AI, including prompt input sizing, sortable columns, and discoverability of the Ask button and AI Bot. He also tested Ask AI against his GitHub triage workflow and reported the “This topic” confusion.

• RBoy filed and followed up on two detailed Gemini bug reports — AI search broken with Gemini and the Flash Lite thinking regression — and raised broader concerns about administrative overhead and TCO as LLM providers churn their APIs. He also reported the missing AI search button in the older one-click experiment topic.

• Karthik_K1 spent the week debugging Gemini API key authentication, testing multiple models and settings to solve the blank Ask AI response, and ultimately pinpointing the theme-related rendering bug on desktop. He closed the Gemini key thread as solved via LiteLLM.

• Lilly helped Karthik_K1 by clarifying that the Gemini API service works fine without Vertex and sharing her working configuration screenshots.

• NateDhaliwal jumped into the AI search button question, asking whether the functionality in the Discourse AI AI Search guide was what RBoy was referring to, and linking to Ask AI as the newer equivalent.

• Ed_S contributed a thoughtful review of the llms.txt template, suggesting a shorter plain-text description of the forum and raising the opt-out question for self-hosters.

• Moin clarified the distinction between classic topic-scoped search and Ask AI in the Ask AI thread, explaining that selecting “This topic” is not part of the Ask AI feature.

Weekly Summary of AI Activity on meta.discourse.org

Overview

This was a busy week for ai on meta.discourse.org, with 74 new posts and 9 new topics between September 7–14, 2026. The headline act was sam's superb Using Discourse MCP to quickly build a theme walkthrough, which showed how to use Discourse MCP, a Discourse trial, and OpenAI Codex to generate a fully custom theme. The thread evolved into a broader conversation about AI agent harnesses, with sam later running a test on DeepSeek 4.1 that produced a full transcript of the agent working through browser and Docker tooling.

Alongside that, there was intense interest in Ask AI and AI-assisted search. nat's Search better in your community with Ask AI announcement thread saw detailed feedback from EricGT, Moin, and others around toggling classic vs. AI search, preserving “in this topic” scope, and whether AI answers should include the current open topic in results. satonotdead raised an interesting question on thumbs up/down in ask.discourse, learning that thumbs down map to flags, and AdamWargon reminded everyone why Discourse historically avoided thumbs-down buttons — to promote dialogue over technically-correct Q&A.

The week also featured several important bug reports and fixes. Steve_Walmsley reported a bizarre Discourse AI going off the rails conversation where the helper AI gave bad advice and denied it; david confirmed the CDCK hosted LLM had been updated to improve things. pedro filed LLM update for Spam Detector Agent not persisting in Features tab, which sam fixed with a PR. Moin spotted that AI Agent group settings don’t seem to be handled by the upcoming change removing the everyone group, and martin quickly opened a fix. Translation workflows also drew attention: Using Discourse and LibreTranslate without AI, How to fix untranslated text in AI translations, and continuing complaints about botched German tag translations in AI-generated tag translations do not work perfectly.

Overall, the theme of the week was practical, hands-on AI: building with agents, evaluating their outputs, fixing the rough edges, and sharing creative workarounds.

Interesting Topics

• Using Discourse MCP to quickly build a theme — sam demonstrated how to take a Discourse trial, generate a global API key, and use Discourse MCP with OpenAI Codex (powered by GPT-6 Astra) to generate a custom theme — fonts, branding, colors, and all. EricGT pointed out that a model thinks, an agent acts, a harness keeps the agent from acting like an idiot, and argued purpose-built AI harnesses are becoming the more interesting part of the story. ducks confirmed it works for self-hosters too and shared before/after screenshots of a community directory theme. Later, sam ran the same task with DeepSeek 4.1 flash max, full transcript included, using Qwen 3 Image for image generation and chrome-devtools-mcp for browser control.

• Discourse AI going off the rails — Steve_Walmsley had a genuinely bizarre experience where the help AI gave bad advice twice, then denied it had ever said those things — even when confronted with screenshots, accusing him of lying. EricGT helped investigate which model was backing the feature, explaining the CDCK Hosted LLM default is actually a Mixture of Models routing layer (see What is CDCK/MoM?), and pointed to the Discourse AI LLM settings page. david later confirmed that fixes had been pushed to the hosted LLM service.

• Search better in your community with Ask AI — The Ask AI announcement thread became a rich source of feedback. EricGT compared Ask AI against ChatGPT for finding related GitHub issues, while Moin noted the classic search toggle was hard to discover and that the “in this topic” filter gets lost when typing more words. nat acknowledged the regression and said they’d look into it. EricGT also documented rough edges like the AI including the currently open topic in its own results and suggesting “Create topic” for new threads where that isn’t wise.

• About thumbs up and down in ask.discourse — satonotdead asked whether the thumbs up/down UI on ask.discourse would be a feature available to everyone, seeing it as an indispensable monitoring tool for AI replies. Falco clarified it’s nothing fancy — thumbs up are likes, thumbs down are flags. AdamWargon added that codinghorror deliberately avoided thumbs-down when designing Discourse to facilitate dialogue and positive human connection.

• AI Agent group settings don’t seem to be handled by the upcoming change removing the everyone group — Moin discovered that enabling the granular anonymous/logged-in groups permission change breaks AI agent permissions: a proofread agent configured for “everyone” no longer appears for logged-in users. martin acknowledged the edge case and quickly opened a fix PR. satonotdead confirmed the pain, noting they’d had to manually add user groups to summary agents to keep functionality working.

• Using Discourse and LibreTranslate without AI — happyhappy, whose community deliberately avoids AI, asked whether the new AI translation wiring in core could be used to connect LibreTranslate instead. NateDhaliwal explained the two paths — the translator plugin (which supports LibreTranslate but is end-of-life) and the ai plugin’s LLM-based content localization — and asked what integration happyhappy would like to see preserved.

• LLM update for Spam Detector Agent not persisting in Features tab — pedro filed a low-severity bug: changing the LLM for the Spam Detector Agent in its configuration doesn’t reflect in the AI Features tab, which still shows CDCK Hosted LLM. sam confirmed it should be fixed by a discourse PR #43566.

• How to fix untranslated text in AI translations — Jagster accidentally left a Finnish sentence untranslated and asked how to fix it. Moin pointed to the translations menu (editable, and flagged as potentially out-of-date while re-translating), and noted that translations are debounced — so removing the original sentence takes a moment to propagate. Moin also shared a funny example of German mistranslation where the boards tag became “kanban-board” and ramping-up became “ausschwingen” (the opposite meaning) in AI-generated tag translations do not work perfectly.

• Ai推理模式报错 — A new Support topic from singi2016cn reported a 400 error from a custom LLM router gateway when using reasoning mode: the provider demands reasoning_content be passed back. Disabling streaming or reasoning mode worked around it but lost reasoning ability. sk-or-v1-contents suggested it looks like a DeepSeek/provider-specific issue and raised the possibility of a feature request to send reasoning tokens back during completion.

• How to set custom helper prompts — A solved Support topic where satonotdead documented a neat trick: instead of custom prompts, reuse unused built-in helper agents and rename their labels via Customize → Text. They mapped ai_helper_translator_agent to a custom search agent, and repurposed helper slots for Composer Translate and Markdown formatting with a small api-initializer snippet for icons.

• Add webhook / event support for Discourse AI artifact key-value updates — This older #Feature request got another nudge from MachineScholar, asking if there are updates on webhook support for AI artifact key-value updates (or letting admins disable sandboxing). The original reply noted this would be revisited once Workflows land, the new approach for Automation in Discourse.

Activity

• sam was the most-liked contributor this week, kicking off the Using Discourse MCP to quickly build a theme tutorial, clarifying he used the vanilla ChatGPT app rather than a custom harness, and later publishing a DeepSeek 4.1 test run with full transcript. He also confirmed the Spam Detector LLM persistence fix PR, shared a Jarvis-generated state diagram writeup for Ask AI, and generally pushed the conversation on multi-LLM workflows forward.

• EricGT was everywhere this week: he dissected the AI harness vs agent distinction, helped Steve_Walmsley diagnose the CDCK/MoM model routing behind the derailed AI, and ran extensive experiments with Ask AI search, including cases where the AI includes the current topic and produces low-quality replies on community.openai.com that he wouldn’t pass human review. He also posted examples comparing Ask AI to ChatGPT for finding related topics, questioning whether RLHF is needed for AI replies.

• satonotdead contributed across many threads: asking about thumbs up/down in ask.discourse, confirming the AI agent group settings issue and the need for manual group assignment, requesting edit and branch for AI Conversations, and sharing a detailed solution for custom helper prompts. They also learned how to import agent skills in Giving Discourse AI agent skills, and mentioned disabling the Suggested Topics selector via CSS in the related discussion on Related vs Suggested Topics.

• Steve_Walmsley reported the alarming AI going off the rails incident with screenshots, worked with EricGT to identify the model and settings, and confirmed he was on the full Pro plan (following his earlier Changing to Full Width thread).

• Moin filed the AI Agent group settings bug, gave feedback on Ask AI search toggles and “in this topic” retention, helped Jagster fix untranslated AI translations, and flagged ongoing German tag translation issues in AI-generated tag translations do not work perfectly.

• ducks confirmed that the MCP theme-building workflow works for self-hosters and shared their own AI-generated theme attempt with before/after screenshots for a PDX tattooer directory.

• nat fielded feedback in the Ask AI announcement thread, clarified that Ask AI is meant to work only within forum context, acknowledged the lost “in this topic” state (noted the regression), and pointed out the interface preference toggle for classic search.

• NateDhaliwal answered the LibreTranslate-without-AI question, noting the translator plugin is end-of-life, and helped satonotdead find the right import location for Discourse AI agent skills (AI > Agents tab, not Workflows).

• david responded to the AI going off the rails report, confirming updates to the CDCK hosted LLM and asking for future reports if issues persist.

• AdamWargon contributed historical context on why Discourse avoids thumbs-down buttons in About thumbs up and down in ask.discourse.

• Other notable participants: Falco clarified the thumbs up/down mechanics in ask.discourse; pedro filed the Spam Detector LLM bug; martin fixed the agent group permission edge case; happyhappy raised the LibreTranslate question; Jagster sought help with untranslated text; mbauman tested manually edited translations and wondered whether edits are visible; singi2016cn reported the reasoning-mode 400 error with sk-or-v1-contents investigating; AJ_Quick argued in Related vs Suggested Topics for curating a single list; and MachineScholar nudged the AI artifact webhook feature request. Also spotted: mcwumbly wanting more multi-LLM examples from sam in MCP theme building, and putty appreciating the realism of ducks’ AI experience.
