Practical
Try it
Something you can actually use or run today.
On September 16, 2026, AWS officially launched prompt caching for Amazon Bedrock and the new AgentCore runtime for managed agent deployments.
Prompt caching drastically reduces costs for long-context applications like RAG and multi-turn coding assistants.
AILookup take
AWS is finally shipping the infrastructure features builders actually need for production—specifically cost control and low-latency starts. Caching is now a mandatory feature for any enterprise provider aiming for production-grade agentic workloads.

Also covers
- Amazon Bedrock Agentcore Launches for Production Agent MonitoringAWS has launched Amazon Bedrock AgentCore, a suite of tools for the production lifecycle of AI agents. It includes 'Agent Evaluation Metrics' (AEM) for pinpointing failures in multi-turn conversations and supports interactive MCP (Model Context Protocol) apps with HTML widgets. The service aims to solve failure modes that traditional monitoring misses, such as agent trajectory drift.
Details
- Immediately alters the pricing dynamics for applications utilizing dense system definitions or static documents.
- Allows multi-turn conversation agents to scale affordably without paying full cost for the entire context history on every turn.
- Increases response speed by bypassing processing tasks for cached prompt fragments.
