OpenAI Python SDK migrates to HTTPX2, drops httpx dependency
mitsuhiko · x · 2026-08-29
OpenAI announced that its Python SDK now uses HTTPX2 for synchronous and asynchronous HTTP clients, installed automatically with the SDK. The legacy httpx package is no longer installed. Users relying on the default client face no breaking changes, but those importing httpx transitively must add their own dependency or migrate. The guide also details changes to TLS certificates and trust stores.
