THEN Use the extra_body field in the request payload to pass the 'thinking' parameter instead of relying on allowed_openai_params. Set `kwargs["extra_body"] = {"thinking": {"type": "disabled"}}` as a workaround until the allowed_openai_params bug is fixed.

payload = {
    "model": "openai/claude-sonnet-4-20250514",
    "messages": [...],
    "extra_body": {"thinking": {"type": "disabled", "budget_tokens": 0}}
}
