Streaming chain of thoughts

[passacagllia]

Describe the feature

I am using Azure OpenAI o3 and o4-mini. I want to stream chain of thoughts like Grok or ChatGpt. I saw Azure Playground can do it. I just can not find the document to do that. Thanks.

You'll need to do a couple of things:

1. In ModelSettings, set Reasoning so that you get chain of thought summaries: https://openai.github.io/openai-agents-python/ref/model_settings/#agents.model_settings.ModelSettings.reasoning
2. When you call stream_events(), you will receive RawResponsesStreamEvent with the data being ResponseReasoningSummaryPartAddedEvent, ResponseReasoningSummaryTextDeltaEvent etc, which you can use to stream.

is there any example using o model family with the agents SDK ?
