I decided to be pessimistic and set higher timeouts on the python OpenAI client, since you have timeout=5.0 reported within:
import httpx
client = OpenAI(timeout=httpx.Timeout(60.0, read=10.0, write=20.0, connect=10.0))
(using OPENAI_API_KEY from the environment is already library behavior)
12.6 seconds from call to response.
