Unclear It is not clear which requests use this fallback.
What
The effort level is the setting that controls how much work the model puts into a reply. When the model service rejects a request with an "Invalid effort level" error, Claude Code can now treat it as an error it can recover from:
It lowers the effort level by one step and tries again.
It remembers the lower level for that model.
It tells you once that the level was lowered.
This recovery stays on unless a remote switch turns it off. That switch is off by default.
Why
If a model does not accept the effort level you picked, the request can still go through at the nearest level below instead of failing.
