What's included

  • Every prompt on every model fails with "Selected model is at capacity. Please try a different model." across Desktop, CLI and Web, even a minimal "hello", while usage allowance remains
  • Long coding tasks stop mid-turn after running tools or editing files; reconnect attempts (2/5, 5/5) and retries keep failing; logs show server_overloaded
  • "Error running remote compact task: Selected model is at capacity" during context compaction
  • Existing long conversations or complex agent tasks fail while new chats or simple questions work; one account or one model fails while another account or model works
  • After the error the turn ends with no automatic retry countdown and waits for a manual Retry

Not included

  • A decline in model answer quality, reported alongside the capacity error in some reports
  • "stream disconnected before completion" errors without the capacity message
  • Usage limit exceeded messages with a reset time
  • Codex desktop app failing to launch
