OpenAI's GPT-5.6 Sol, Terra and Luna models are now available in AWS Kiro, a spec-driven development environment, according to the announcement described by Unite.AI. The integration supports turning requirements into implementation plans, multi-step coding work, checkpoint review and property-based testing. OpenAI and AWS reported that joint testing of GPT-5.6 Terra in Kiro on Terminal-Bench 2.1 reduced the cost of completed tasks by roughly 82%, which the source attributes to Kiro's added requirements and task context.
