Claude Opus 4.7 and later reject non-default sampling parameters

Anthropic has deprecated temperature, top_p, and top_k on Claude Opus 4.7 and later; non-default values return an HTTP 400 error.

breaking behaviorStop sending temperature, top_p, and top_k for affected models. Express tone, variability, and formatting requirements in the system prompt instead.

Claude Sonnet 5 changes thinking defaults and token counts

Claude Sonnet 5 enables adaptive thinking by default, removes manual thinking budgets, rejects non-default sampling parameters, and tokenizes the same text into roughly 30% more tokens.

breaking behaviorRemove manual thinking budgets and non-default sampling parameters, rely on adaptive thinking, and use Anthropic's token-counting API to recalibrate limits and cost controls.

Gemini deprecates temperature, top_p, and top_k

Gemini 3.6 Flash and 3.5 Flash-Lite ignore the sampling parameters; Google says future model generations will return HTTP 400 when they are supplied.

parameter deprecationStrip temperature, top_p, and top_k from Gemini requests and encode response constraints in a clear system instruction.
