Advancing price-performance for developers with GPT‑5.6 in Kiro

OpenAI's GPT-5.6 model family is now available in Kiro, a software development agent that helps teams write code more efficiently using AI. The new models (Sol, Terra, and Luna) integrate into development workflows to help developers create higher-quality code with fewer iterations and better cost-effectiveness. Kiro uses spec-driven development (structuring AI coding tasks around clear requirements and specifications) to help GPT-5.6 understand what needs to be built, resulting in faster solutions with fewer mistakes.
