AWS Upgrades AgentCore Runtime for Faster Starts and More Compute for AI Agents

At a glance

AWS has upgraded AgentCore runtime, a managed environment for running AI agents. Sessions now start faster, can use more computing resources, and run more efficiently, the company said.

Key points

1. 1

   Each session runs in its own hardware-isolated virtual machine (MicroVM).

2. 2

   Session startup is up to 15 times faster, and available computing power is up to 4 times greater.

3. 3

   Each session can use up to 8 vCPUs and 32 GB of memory, and supports container images up to 10 GB.

4. 4

   Sessions start in under 2 seconds without pre-warmed resources, which reduces cold-start delays.

Why it matters

For agents to be used in real work, security, speed, and cost must be balanced, and this upgrade aims to strike that balance.
