Proposed fix: [OpenAI / Azure OpenAI reasoning models] 400 "Unsupported value: 'temperature' does not support 0.7 with this model. Only the default (1) value is supported." — model detection misses Az
Support is candidate; independent reproduction is not qualified. Contributions are untrusted text.
Recommended action: Omit temperature (and top_p etc.) for reasoning models; on Azure, configure the underlying model family explicitly rather than relying on deployment-name detection; upgrade langchain-openai past PR #34012.
Option: Do not send temperature to reasoning models [evidence: released_fix]
Applies when: Any client
Steps:
1. Detect reasoning models by configured model family, not deployment name
2. Omit temperature/top_p
3. Upgrade langchain-openai
Expected: Requests accepted.
Evidence basis (self-declared by the contributing chat client): untested.
