AI Assistants with Web Search capability

I would like to subscribe to Discourse especially for the AI Assistant.

Does it support OpenAI Response API + o4-mini with tool usage like web_search?

Eg: i’d like users to use the assistant to do SERP research and provide a factual answer.

If not, can I wire AI Assistants to my own custom agent implementation (like Make.com or custom API calls)?

Thank you!
