AWS announced that Amazon Bedrock AgentCore now charges for short-term memory (STM) based on data ingestion, retrieval, and storage volumes, aiming to align costs with actual usage. The pricing differentiates three components: ingestion at $1.00/GB, retrieval at $0.20/GB, and storage at $0.10/GB-month, with event size billing parameters to accommodate small payloads.
This consumption-based approach tends to reduce costs for workloads involving frequent small events and offers flexibility to control expenses by adjusting memory resource time to live (TTL). Long-term memory pricing remains unchanged. The new pricing model is available in all regions that support AgentCore Memory.
