OpenAI Developers(@OpenAIDevs):Programmatic Tool Calling lets GPT-5.6 write and run JavaScript to coordinate complex tool workflows, process results, and decide what to do next. That means fewer model round trips, fewer tokens, and less orchestration for developers. Programs run in isolated hosted V8 runtimes, so developers get stateless code-driven orchestration without managing containers.
