What's the cheapest/best AI to use for AI Spam?

[trusktr (Joseph Orbegoso Pea (Joe Pea))]

I’m trying to save some money.

Any recommendation on which AI will be cheapest, yet do a good enough job with Spam handling?

I have little experience comparing AIs, and this will be my first time using them for Discourse; hoping someone may have more experience to chime in with.

Also is “Support” the best category for a question like this?

Discourse already has an AI plugin and you can set up to detect spam.

@ondrej Oh yeah I know, I’m wondering about the LLMs. I’ve installed the plugin already.

I’m wondering which one to pick to save money but so that Spam handling will work well enough. Maybe the absolute cheapest one may not work well enough for example? I’m just getting started.

EDIT: Ah, it mentioned there:

Most low-cost LLMs work effectively, such as:

• GPT-4o-mini
• Claude 3.5 Haiku
• Gemini 2.0 Flash

Ok then, I’ll try one of those!

I use OpenRouter’s Gemini for my spam detector, but it doesn’t seem to work for AI chats. It’s free.

When it comes to great bang for buck Gemini 2.0 flash is right up there. It both has a free tier, and for pay tier which comes in (today) at 10 cents for 1 million input tokens. 4o-mini can do the job but is a bit more expensive.

Agree here with @NateDhaliwal that openrouter is a good place to hunt for great deals.

I would like to extend this question with “… where all data remains in Europe.”

As far as I understand, OpenRouter does not support the regional selection of providers.

Is anyone aware of a similar European service?

I would consider Community wiki a good place to keep this updated.

However, I cannot gauge whether an initial question will receive sufficient attention there…

@thoka

where all data remains in Europe.

Try Mistral Small 3.1 via their official API?

Should cost you less than an euro per month.
