Hey, thanks for the report. To understand why your PoE API calls are failing, please share:

  • Error message: What exact message do you see when the request fails?
  • Configuration screenshot: Settings → Models → API Keys section with your PoE setup
  • Base URL: What Base URL are you using for PoE?
  • Request ID: After a failed attempt, open and send the Request ID
  • Account type: Are you on a Team/Business plan?

In the meantime, please check:

  • That your PoE API key has permissions for the required model
  • That the model name matches what PoE expects (case-sensitive)

Let me know what you find!
