GPT-6 Astra is the most capable model to date. It delivers outstanding performance in computer use, browsing, software engineering, scientific research, and professional work. It is especially strong at executing multi-step workflows across code, the browser, and professional software, acting with care, respecting task boundaries, and communicating transparently.
