I’m testing the new Responses API and trying to use the `generate_summary` attribute for reasoning models. However I’m consistently getting the following error:  
`openai.BadRequestError: Error code: 400 - {'error': {'message': "Unsupported parameter: 'reasoning.generate_summary' is not supported with the 'o3-mini-2025-01-31' model.", 'type': 'invalid_request_error', 'param': 'reasoning.generate_summary', 'code': 'unsupported_parameter'}}`

I also tried it with o1, but the same error occurs.

Has this feature not been enabled yet?
