Expected behavior

A clear and concise description of what you expected to happen.

Currently, I have only changed all the models in the example financial_research_agent to qwen3-32b. However, in the case of the writer_agent, it used two other agents as tools to pass them in, which caused an error in the qwen3 model.

The change is as follows:

custom_client = AsyncOpenAI(
    base_url="xxxx",
    api_key="xxxxx"
)
model_name = 'qwen/qwen3-32b'

set_default_openai_client(custom_client)
set_tracing_disabled(disabled=True)

The error is as follows:

openai.BadRequestError: Error code: 400 - {'error': {'message': 'Provider returned error', 'code': 400, 'metadata': {'raw': '{"message":"\\"tools\\" is incompatible with 
\\"response_format\\"","type":"invalid_request_error","param":"tools","code":"wrong_api_format"}', 'provider_name': 'Cerebras'}},
