AWS has increased the default runtime quota limits for Amazon Bedrock AgentCore to support larger-scale agent workloads. The update allows up to 5,000 active concurrent sessions in US East (N. Virginia) and US West (Oregon), while other regions support 2,500. Across all available regions, the service now handles 200 agent interactions per second and 25 new session creations per second by default.
- US East and West regions now support 5,000 active concurrent sessions by default.
- All other supported regions support 2,500 active concurrent sessions by default.
- Global throughput limit is 200 agent interactions per second across all regions.
- New session creation rate is capped at 25 per second in all regions.
- Higher default limits reduce the need to request quota increases for high-scale agents.
