Anthropic Claude 4.7 Rejects Non-Default Sampling Parameters
Sep 19, 202610 min0 plays
The question this episode answers
When an application sends shared sampling settings to Claude Opus 4.7, what exactly must change so the request remains reliable without silently changing behavior on other models?
Applications that pass shared inference settings should remove or conditionally gate `temperature`, `top_p`, and `top_k`, because non-default values now produce HTTP 400 errors on Claude Opus 4.7 and later.
