## Timeline of updates

- **identified** 2025-10-22 17:56 UTC: We are currently seeing longer-than-usual turnaround times for pre-recorded audio transcriptions that are using our Slam-1 model. Requests using the Universal model are unaffected. We are working to address this issue and will provide an update here as soon as possible.
- **identified** 2025-10-22 18:01 UTC: We are now seeing increased error rates and failures for requests using the Slam-1 model so we are elevating this issue to a partial outage. Requests using Universal are working normally, so consider using that model as a short-term workaround if needed. Our team is working to resolve this issue as quickly as possible.
- **identified** 2025-10-22 19:03 UTC: We are once again starting to see requests using Slam-1 succeed, but we are still working to fully resolve the issue. We will follow up with another update once the issue has been fully mitigated.
- **identified** 2025-10-22 19:20 UTC: We are still seeing good success rates for requests using the Slam-1 model, but we are still seeing occasional slower-than-usual processing times, which we are working to address.
- **monitoring** 2025-10-22 19:37 UTC: Success rates and turnaround times for requests using Slam-1 have returned to normal ranges, but we are continuing to monitor traffic to ensure continued good performance.
- **resolved** 2025-10-22 23:58 UTC: We have continued to see good performance for requests using Slam-1 and are now marking this issue as resolved.
