Get started with OpenAI GPT-5.6 Sol, Terra, and Luna on Amazon Bedrock

This article announces the general availability of OpenAI GPT-5.6 Sol, Terra, and Luna models on Amazon Bedrock, enabling developers to access frontier AI models through familiar APIs with AWS security and regional processing.

• Sol is optimized for autonomous coding and deep reasoning; Terra balances performance and cost for production workloads; Luna prioritizes fast, low-cost inference
• Access all three models through the OpenAI Responses API on the bedrock-mantle endpoint with 272K-token context windows
• Implement prompt caching in explicit or implicit modes to reduce costs by 90% on cached input tokens for repeated context
• Connect OpenAI Codex coding agent to Amazon Bedrock for in-region inference with AWS access controls
• Pricing matches OpenAI first-party rates; cached tokens don't count against input-token quotas
• Requests are logged in CloudTrail, run under IAM policies, and prompts aren't used for model training

Developers can now build agentic applications, long-horizon reasoning tasks, and high-volume inference workloads using frontier models with enterprise security and cost optimization.
