Instrument OpenAI Responses API

[alexmojaki]

What problem do you want to solve?

OpenAI has introduced a new 'Responses API' as an alternative to the chat completions API. Some models like https://platform.openai.com/docs/models/o1-pro only support the Responses API. Currently this records nothing even when exporters are configured:

import os

import openai
import opentelemetry.instrumentation.openai_v2

os.environ['OTEL_INSTRUMENTATION_GENAI_CAPTURE_MESSAGE_CONTENT'] = 'true'
opentelemetry.instrumentation.openai_v2.OpenAIInstrumentor().instrument()

response = openai.responses.create(model='gpt-4o', input='hi')
print(response)

Describe the solution you'd like

Methods of the Responses API should be instrumented in the same manner as the chat completions API.

Describe alternatives you've considered

No response
