A post describes prompt caching in Amazon Bedrock and says it can cut input token costs by up to 90% when the same context is repeatedly sent to foundation models.
Amazon Bedrock prompt caching is described as a way to cut input token costs by up to 90% when the same context is repeatedly sent to foundation models. The source lists six practical scenarios using the Converse API: message content, system prompt, tool definition, mixed TTL, tenant isolation, and LangChain integration.
For a repeatable workflow, the relevant step is the repeated context send; the integration points named are the Converse API and LangChain.
