Hi all, Thariq from the Claude Code team here. I posted this on Twitter, but just reposting here:

We sometimes test API serving configs in Claude Code before rolling them out, and one running now maps the numerical effort value differently.

That's why Claude may tell some of you it's at "10" on high. The scale isn't 0-100, the number isn't meaningful on its own, and the effort you selected is the effort you're getting. We've run in-depth evals to confirm this doesn't affect model performance.

This should be the same experience, but if you see a clear regression please hit /feedback and send me the ID. Will give credits.

Let us know if this A/B test uncovers any load-bearing seams or honest takes on your end! We're all interested.

Thanks for sharing this here, for those of us who avoid X.com like the plague.
