openai-python v3.19.0: GCP external storage and GPT-Rosalind
Release 3.19.0 (2026-09-22) adds GCP external storage support and the GPT-Rosalind research model, and includes bug fixes for async, client, and WebSocket behaviors.
What changed
Adds GCP external storage support and GPT-Rosalind research model; fixes: propagate __api_exclude__ in _async_transform_recursive; handle omission markers in queued WebSocket events; retry only replayable request content; tolerate older optional aiohttp; use asyncio.get_running_loop() inside async methods.
Why it matters
Developers can access GCP external storage and researchers can try the GPT-Rosalind model; async clients and WebSocket/event users should see fewer compatibility workarounds.
