Update timeline

  1. investigating Aug 31, 2026, 05:07 PM UTC

    We are currently experiencing elevated error rates and API hangs communicating with OpenAI. We are investigating the issue.

  2. investigating Aug 31, 2026, 05:14 PM UTC

    We are currently investigating this issue with OpenAI. We are seeing some inconsistent response times from OpenAI.

  3. investigating Aug 31, 2026, 05:21 PM UTC

    We are continuing to see fluctuating availability and response times from OpenAI across multiple model classes. We are continuing to investigate and implement mitigations.

  4. monitoring Aug 31, 2026, 05:32 PM UTC

    We are seeing consistent availability from the OpenAI endpoint, but performance remains degraded. We are continuing to monitor the situation.

  5. monitoring Aug 31, 2026, 05:45 PM UTC

    We are continuing to observe inconsistent response latencies with OpenAI endpoints. We are deploying a mitigation to failover all remaining affected model usages to Anthropic.

  6. monitoring Aug 31, 2026, 06:26 PM UTC

    We are continuing to failover to Anthropic models for remaining affected agent behaviors and monitoring rollout.

  7. monitoring Aug 31, 2026, 06:58 PM UTC

    We are continuing to failover to Anthropic and are implementing other mitigations.

  8. monitoring Aug 31, 2026, 07:17 PM UTC

    We have completed failing remaining inference activity to Anthropic and are continuing to monitor OpenAI endpoints for recovery.

  9. monitoring Aug 31, 2026, 07:43 PM UTC

    We are recording improved API responsiveness from OpenAI and are evaluating a progressive rollback to normal operations.

  10. monitoring Aug 31, 2026, 08:16 PM UTC

    We are continuing to observe issues with OpenAI API responsiveness, so will maintain failover to Anthropic models and continue monitoring.

  11. monitoring Aug 31, 2026, 09:34 PM UTC

    We are continuing to use Anthropic for all agent responses as we monitor OpenAI API recovery.

  12. monitoring Aug 31, 2026, 10:51 PM UTC

    We are continuing to use Anthropic for all agent responses as we monitor OpenAI API incident response and recovery. Follow OpenAI's status updates here:

  13. resolved Sep 01, 2026, 02:43 AM UTC

    We are continuing to use Anthropic for all agent responses as we monitor OpenAI's recovery. We will return to normal operation once API responsiveness returns to expected baseline.
