Get started with OpenAI GPT-5.6 Sol, Terra, and Luna on Amazon Bedrock | Amazon Web Services
This post is co-written with Chris Dickens from OpenAI.
Developers building agentic coding, long-horizon reasoning, and high-volume inference workloads want frontier models they can call through familiar APIs, without operating separate model infrastructure. OpenAI GPT-5.6 Sol, Terra, and Luna are now generally available on Amazon Bedrock. The three models cover workloads from autonomous coding agents and long-horizon reasoning to high-volume, latency-sensitive inference, and they run with the security, Regional processing, and cost controls of AWS.
You access all three models through the OpenAI Responses API on the bedrock-mantle endpoint. Sol is the flagship reasoning model, Terra balances performance and cost for everyday production work, and Luna is optimized for fast, low-cost inference, so you can right-size capability and cost for each workload. Pricing matches OpenAI first-party rates, and usage counts toward your existing AWS commitments.
In this post, we show you how to select a model, run your first...
