Summary
Amazon moved its original Bedrock Agents service (launched November 2023) into maintenance mode as Bedrock Agents Classic, closing it to new customers on July 30, 2026 and freezing its model catalog. Existing workloads keep running with security fixes only, while AWS directs new agent development to Amazon Bedrock AgentCore.
What changed
Effective July 30, 2026, Amazon Bedrock Agents became Bedrock Agents Classic in maintenance mode: no new customer sign-ups, no new feature development, and a frozen model catalog (new models ship only via AgentCore). AWS recommends migrating Classic workloads to Amazon Bedrock AgentCore (Runtime, Memory, Gateway, Identity, and the GA AgentCore Harness).
Why it matters
Signals AWS consolidating its agent stack around AgentCore's session-as-cloud-resource model barely two years after launching Bedrock Agents, forcing a migration decision on existing users. Reflects the broader shift from monolithic managed agents to composable agent-runtime primitives.
