OpenAI’s Build Hour focuses on how to get more value out of GPT-5.6 in production workflows.
The session covers how to choose between GPT-5.6 Sol, Terra, and Luna based on intelligence, latency, and cost; how to measure cost-performance on real workloads; and how to adapt evals, harnesses, tool schemas, and prompt caching when migrating agents. A customer example from Ploy says the move to GPT-5.6 made builds 2.2× faster and cut cost by 27%.
