Introducing explicit prompt caching for OpenAI GPT-5.6 models on Amazon Bedrock
AWS Machine Learning Melanie Li ● Covered by 2 sources
OpenAI's GPT-5.6 models (Sol, Terra, and Luna) are now available on Amazon Bedrock with explicit prompt caching, allowing developers to mark which portions of prompts are cached and reused across requests. Cached input is billed at a 90 percent discount compared to standard rates and remains available for 30 minutes, with the feature most valuable for agentic workflows that repeat system instructions and reference documents. Organizations can now use the same OpenAI models through AWS infrastructure with pay-per-token pricing and AWS governance controls, and existing code automatically benefits from implicit caching without configuration changes.
Why it matters
OpenAI GPT-5.6 Sol, Terra, and Luna are now generally available on Amazon Bedrock, along with explicit prompt caching that gives you precise control over which parts of your prompt are cached and reused. Learn how to get started, set up explicit caching, and migrate existing GPT workloads to reduce inference cost.
