Amazon Bedrock prompt caching cuts input token costs up to 90%
Amazon Bedrock now supports prompt caching, which can reduce input token costs by up to 90% when the same context is repeatedly sent to foundation models. An AWS blog post details six scenarios using the Converse API: message content, system prompt, tool definition, mixed TTL, tenant isolation, and LangChain integration.
