OpenAI Responses API native support

[AlejandroBaron]

Currently, there are two options to run search using OpenAI's models

1. Chat API
   https://platform.openai.com/docs/guides/tools-web-search?api-mode=chat
2. Responses API
   https://platform.openai.com/docs/guides/tools-web-search?api-mode=responses

If I'm not mistaken, the latter runs the search only when needed (like in the chatgpt GUI), whereas the former always runs it.
In autogen access is currently available through OpenAIChatCompletionClient, but I see no option to use the responses API functionality.

Is this a feature we can expect down the roadmap?
