Cause (Documented platform behavior): Reported SDK/integration bug; the documented mechanism is model_extras, which inserts extra JSON at the request root and adds header 'extra-parameters: pass-through' (service rejects unknown params by default).
Fix status: unknown
Limitations:
- Issue closed with 'issue-addressed' label; no merged PR or changelog entry cited.
Unknowns:

Affected versions: unknown Environment: unknown Exception: TypeError Packages: azure-ai-inference 1.0.0b9 (reported) Trigger: extra_parameters forwarded as a kwarg to the aiohttp transport instead of as model_extras.

Proposed fix: [azure-ai-inference 1.0.0b9 / Semantic Kernel] "ClientSession._request() got an unexpected keyword argument 'extra_parameters'" when passing GPT-5 reasoning params
Recommended action: Pass model-specific params via model_extras on ChatCompletionsClient.complete (header added automatically) or upgrade to the addressed version; for Azure OpenAI deployments prefer the official openai client.
