Right now, GPT‑5.5 is being rolled out in ChatGPT and Codex for paid users, but it is not generally available in the API yet. If you don’t see it yet, that’s expected because the rollout is gradual. [7][10]
In ChatGPT, open the model selector and choose:
Thinking for GPT‑5.5 Thinking on supported paid plans. [7]
Pro for GPT‑5.5 Pro if you’re on Pro, Business, Enterprise, or Edu. [7]
If you’re on Go, GPT‑5.5 Thinking is accessed from the tools menu via the + button in the chat box, not the normal model picker. [7]
If you’re on Plus, Pro, Business, or Enterprise and still don’t see it, wait a bit and refresh/sign out-in, since OpenAI says availability is rolling out gradually. [7][10]
If you want it via API, there isn’t a normal public API launch yet; OpenAI says GPT‑5.5 and GPT‑5.5 Pro are coming to the API “very soon.” [7][10]
The current API docs still surface GPT‑5.4 as the latest guided model entry, which matches the “not in API today” rollout status. [1]
If you want, I can give you the exact steps for either:
