What issue are you seeing?
Description
Got a 503 with auth error code: biscuit_baker_service_me_circuit_open immediately after quitting and reopening Codex, on a basic/simple question. I have plenty of usage remaining and am on the Max plan, so this doesn't appear to be a quota or rate-limit issue.
Error output
unexpected status 503 Service Unavailable: Service Unavailable, url: https://chatgpt.com/backend-api/codex/responses, cf-ray: a209fbb14b0c4af5-LHR, auth error: 503, auth error code: biscuit_baker_service_me_circuit_open
What steps can reproduce the bug?
- Ask a basic/simple question in the ChatGPT app
- Request fails immediately with the above 503
What is the expected behavior?
The model should answer.
Additional information
Shortly before this, I also got a separate 503 ("error":"Too many concurrent requests", "code":"throttled", "source":"concurrency_limit") on the same account — noting in case they're related, though they look like distinct failure modes (client-side throttle vs. server-side circuit breaker).
At the time, https://status.openai.com showed no active incident, though there have been other reports of biscuit_baker_service_me_circuit_open tied to a partial outage.
