## Updates from AssemblyAI
### 2026-03-30 18:41 UTC: identified
AWS Bedrock is currently experiencing issues that are leading to an increase in errors for Claude models. This increase in errors seems to be primarily with Sonnet 4.6, but could also affect other Claude models. We are working with their team to monitor the status of this issue and will provide additional updates as soon as we know more. LLM Gateway models from other providers are currently unaffected by this AWS Bedrock issue.

### 2026-03-30 21:54 UTC: identified
The AWS Bedrock issues affecting some Claude models through LLM Gateway, mainly Sonnet 4.6, are still occurring, but the frequency of those errors has gone down. We are continuing to closely monitor the issue for a resolution.

### 2026-03-30 23:55 UTC: resolved
The AWS Bedrock issues have been resolved, and we have once again seen success rates for Claude models, including Sonnet 4.6, return to normal levels.
