It seems that extra-usage is required to use the 1M context window for Sonnet 4.6. This differs from Sonnet 4.5, which allows usage of the 1M context window with a Max plan.

I was just looking into this today but it seems pricey. $29/user/month for basic features like codeowners and defining pr approval requirements. Going with Forgejo.
Anyone have alternatives to recommend? We will be switching after this. Already moved to self-hosted action runners and we are early-stage so switching cost is fairly low.
> FWIW Deep Research doesn’t run on whatever you pick in the model selector. It’s a separate agent that uses dedicated o‑series research models: full mode runs on o3; after you hit the full‑mode cap it auto‑switches to a lightweight o4‑mini version. The picker governs normal chat (and the pre‑research clarifying Qs), not the research engine itself.
