Repeated 500 Errors on 5.2 Codex

[krubenok]

Describe the bug

Fairly long conversation and will end up with errors like this with GPT 5.2 Codex, have also seen it with plain 5.2 as well as 5.1 Codex:

Affected version

0.0.382 Commit: 18bf0ae

Steps to reproduce the behavior

Long (ish) running conversation with an OpenAI Model.

... somewhat randomly ...

500 errors.

Expected behavior

No 500 errors - either compaction, rate limits or something explainable.

Additional context

macOS, running in Ghostty. Not an issue with Claude models only GPT 5.x models.

Hi! There was an availability incident yesterday that might have been the cause of this. Are you still experiencing these errors?

[krubenok]

It's been on and off intermittent for about 2 weeks on the 5.x models. Always that 500 error though, not rate limits or capacity errors. I'll try again this morning to get a repro but the usual experience has been that waiting ~20 minutes in a thread that is repeatedly giving these errors will get some success for a while, then start to fail again.

Well very convenient, I still had everything open from yesterday when I reported so I just prompted to try again and... yep still getting 500's.
