Responses API (Reasoning)

Responses API (Reasoning Models)

Use the responses API to query o-series and similar models that provide reasoning efforts.

1 from meshapi import ResponsesParams
2 
3 reply = client.responses.create(
4     ResponsesParams(
5         model="openai/o4-mini",
6         input="Explain the halting problem in two sentences.",
7         reasoning={"effort": "medium"},
8         max_output_tokens=512,
9     )
10 )
11 
12 print(reply.output)

Streaming works the same way via client.responses.stream(params).
