GPT-5.6 introduces three models designed for different purposes: Sol focuses on advanced reasoning and agentic coding, Terra offers efficient performance close to prior generations at reduced cost, and Luna emphasizes fast and affordable inference. These models integrate with Amazon Bedrock’s next-generation inference engine, promising improvements in efficiency and scaling for tasks like coding, genomics, and cybersecurity research. Amazon Bedrock supports prompt caching with significant cost discounts on repeated context usage.
The models are regionally available with Sol limited to US East regions, while Terra and Luna extend also to US West. Pricing aligns with OpenAI’s first-party rates, and usage applies toward AWS commitments. This offering enables developers to build autonomous coding agents and perform complex analyses without managing underlying infrastructure.
