OpenAI brings GPT-5.6 to AWS Kiro, slashing coding costs by 82%
OpenAI just integrated its GPT-5.6 family—Sol, Terra, and Luna—into AWS's AI-native software development agent Kiro. By combining the models with Kiro's spec-driven workflow to convert requirements into structured tasks, GPT-5.6 Terra achieved an 82% cost reduction on Terminal-Bench 2.1. It basically means teams get cleaner implementations with far fewer wasted tokens.
