SUMMARY:Anthropic: Claude Opus 4.7 and later reject non-default sampling 
 parameters
DESCRIPTION:Anthropic has deprecated temperature\, top_p\, and top_k on C
 laude Opus 4.7 and later\; non-default values return an HTTP 400 error.\n
 \nAffected: claude-opus-4-7\, claude-opus-4-8\, claude-opus-5\, claude-so
 nnet-5\n\nAction: Stop sending temperature\, top_p\, and top_k for affect
 ed models. Express tone\, variability\, and formatting requirements in th
 e system prompt instead.\n\nOfficial source: https://platform.claude.com/
