## Updates from Factory

### resolved, 2026-08-07 21:14 UTC

We deployed a backend fix for the errors affecting OpenAI models and have confirmed that error rates returned to normal. Users can resume normal usage; no Factory CLI or Desktop update or other action is required.

### monitoring, 2026-08-07 18:49 UTC

To mitigate the issue, users encountering 431 errors should update to Factory CLI `0.188.0` or newer, or Desktop `0.145.0` or newer

### monitoring, 2026-08-07 18:32 UTC

We continue to investigate 431 errors from OpenAI models. We advise temporarily switching to non-OpenAI models for uninterrupted workflow.

### monitoring, 2026-08-07 16:12 UTC

OpenAI models may return 'Error: 431 status code (no body)'. We are in communication with OpenAI and awaiting resolution.
