Announcing consumption-based pricing for short-term memory in Amazon Bedrock AgentCore

Amazon Bedrock AgentCore memory now prices short-term memory (STM) based on the data your agents ingest, retrieve, and store, replacing the previous flat rate per event. AgentCore memory gives agents in-session context through short-term memory and persistent knowledge across sessions through long-term memory. With consumption-based pricing, developers building agents that write frequent, small events pay in proportion to what they use.

STM is priced across three dimensions: ingestion at $1.00 per GB, retrieval at $0.20 per GB, and storage at $0.10 per GB-month. Ingestion and retrieval are billed per event with a 12 KB minimum and 64 KB maximum billable size, while storage is billed on each event’s actual size. Most workloads see lower costs, with small-payload use cases seeing the largest reductions. You can manage storage costs by setting a shorter time to live (TTL) on your memory resources. Long-term memory pricing is unchanged.
