GPT-6 Astra Migration Guide

Documentation rather than an announcement, and useful for what it makes explicit about moving to Astra. It names the model as OpenAI's current best for computer use, browsing, software engineering and professional work, and claims stronger results at fewer output tokens. The migration constraints matter more than the praise: no none reasoning effort, fast mode unavailable under EU data residency, and temperature, top_p and top_logprobs removed outright. Raise effort from none or minimal to low, and use the Responses API for tool calling.
