AWS has increased the default runtime quota limits for Amazon Bedrock AgentCore to support larger-scale agent deployments. Concurrent session caps now reach 5,000 in US East and West, while all regions support 200 interactions per second and 25 new sessions per second. These adjustments allow developers to handle high-throughput workloads without immediately requesting quota increases.
- US East and West regions now support 5,000 active concurrent sessions by default.
- All regions support 200 agent interactions per second and 25 new sessions per second.
- Higher default limits reduce friction for scaling high-throughput AI agent workloads.
- Monitor actual usage against these new caps to avoid unexpected throttling.
