Today we’re announcing updates to AgentCore runtime that meet those demands.
What happened
AWS announced updates to the Amazon Bedrock AgentCore runtime, including sessions that start in under 2 seconds, scale up to 8 vCPUs and 32 GB, and support container images up to 10 GB. The runtime can reclaim unused memory and let idle agents scale to zero, while sessions retain hardware isolation. The updated runtime is available today in AWS Regions across North America, South America, Europe, and Asia Pacific.
Why it matters
The update combines faster startup, larger sessions, usage-based memory billing, and data storage within the isolation boundary, giving teams concrete infrastructure changes to weigh when moving agents into production.

AWS updated Amazon Bedrock AgentCore Runtime with session startup times under 2 seconds, capacity up to 8 vCPUs and 32 GB, and support for container images up to 10 GB. AWS says startup time is independent of image size and concurrency, and the new runtime is available in its North America, South America, Europe, and Asia Pacific Regions. The runtime can reclaim memory within minutes after an agent releases it and scale idle agents to zero. For always-on agents, AWS offers committed baseline pricing that sets a minimum memory charge per session while allowing on-demand bursts up to four times the baseline.
