Summary

OpenAI's GPT-5.6 Sol, Terra, and Luna models are now generally available on Amazon Bedrock, introducing a new family of frontier intelligence. GPT-5.6 features a tiered naming system: Sol is the flagship reasoning model, achieving 80 points on the Artificial Analysis Coding Agent Index (2.8 above the next-best) and 73.5% on ExploitBench for cybersecurity, while using less than half the output tokens and costing one-third less. Terra is a balanced model for everyday production, and Luna is a fast, affordable option for high-volume inference. Amazon Bedrock's inference engine supports these models with pooled capacity for demand spikes, in-Region inference for data residency, and prompt caching with a 90 percent discount for cached input, available for at least 30 minutes. The models feature OpenAI's robust safety stack, complemented by Bedrock's hardware-enforced zero-operator access security, IAM policies, VPC integration, and CloudTrail logging. GPT-5.6 also powers ChatGPT Work and Codex agents. Sol is available in US East (N. Virginia) and US East (Ohio), with Terra and Luna also in US West (Oregon).

Key takeaway

For AI Architects evaluating LLM deployments, OpenAI's GPT-5.6 models on Amazon Bedrock offer a compelling solution. You can right-size model tiers (Sol, Terra, Luna) to optimize performance and cost for specific agentic or high-volume tasks. Utilize prompt caching for up to a 90% discount on repeated context, significantly reducing operational expenses. Your data benefits from hardware-enforced zero-operator access security and in-Region inference, meeting strict compliance needs. Consider integrating these models for scalable, secure, and cost-efficient frontier intelligence.
