API returning 500 errors intermittently on gpt-4o since this morning

Starting around 9am EST today, we're seeing intermittent 500 errors on gpt-4o completions. About 20% of requests fail.

Error response:

{
  "error": {
    "message": "The server had an error while processing your request.",
    "type": "server_error",
    "code": "internal_error"
  }
}

Our retry logic handles it but latency is way up. Is anyone else seeing this? The status page shows all green which is confusing.

Update: OpenAI confirmed the issue and it was resolved around 2pm EST.

Is the Chat Completions API being deprecated or can we continue using it?

Good to know. I'll migrate new features to Responses API but won't touch the existing Chat Completions code. If it ain't broke...
