A model and the product around it are different things: a result for one does not carry over to the other.
Where can it be used?
Only recorded availability statements are shown. A missing plan or surface means unknown, not unavailable. Where it applies only to a plan or a region, the row says so. “Rolling out” is not “available”. “Rollout reported” means a rollout was reported, but nothing has supported it for more than 90 days.

Where a start is “not documented”, a source check found the state in place; the source names no start date.
No statement on record for 10 further products: ChatGPT, ChatGPT Work, Claude, Codex, Gemini, Gemini for Google Workspace, Grok, Langdock, Le Chat Enterprise, Microsoft 365 Copilot. No statement is not the same as not available.
