nforum bolts OpenAI onto Mike as a third brain option

Mike forks have leaned on Claude and Gemini; nforum opens the door to GPT as well.

infrastructureintegration

nforum has added OpenAI's GPT models - both the flagship GPT-5.5 and the lighter-weight GPT-5.4 Nano - as a first-class option inside Mike, sitting alongside the Claude and Gemini engines the codebase already supports. Users bring their own OpenAI key, store it on their account, and the relevant models light up in the model picker; no key, no option.

The lighter Nano model is wired in as the default workhorse for the kinds of tasks that don't need a heavyweight model - pulling structured data out of documents, generating titles, that sort of thing. It's a clean copy of the pattern Mike already used for its other providers, which makes it easy for downstream forks to lift.

So what For any legal-tech team running Mike, this is the cheapest path yet to a multi-model deployment - useful both for cost arbitrage and for hedging against any single AI vendor's outages or policy shifts.
