> Opus 4.7 and later
The source of truth should be the API docs which make it clear 4.8 didn't bring back extended thinking: https://platform.claude.com/docs/en/about-claude/models/over...
Any UI settings probably just map to changing the effort nudge on adaptive thinking
Adaptive thinking supports effort, but it's a nudge instead of an actual token budget.
Why not use the pages that plainly state they don't support extended thinking: https://platform.claude.com/docs/en/build-with-claude/extend...
Thank you for pointing this out.
