GPT-6 Astra is OpenAI's latest flagship model, framed by the company as a "new capability level" that CEO Sam Altman said has changed his own workflows. OpenAI began a phased rollout in early September 2026, first granting access to companies in its application-based cybersecurity program, then expanding to ChatGPT Plus, Pro, Business, and Enterprise users, the OpenAI API, and Amazon Web Services. The model is described as state-of-the-art across computer use, software engineering, professional work, and science, and OpenAI highlights improvements in staying oriented, respecting task boundaries, understanding user intent, completing tedious tasks, and carrying out multi-step workflows.
On Amazon Bedrock, GPT-6 Astra is positioned for demanding business workflows that require deeper reasoning and judgment, professional-quality writing and design, and advanced computer and browser use. The model supports a context window of up to one million input tokens and can produce output aligned with organizational voice, templates, and standards, making it well suited for building autonomous agents, analyzing extensive document collections, investigating complex software issues, and adjudicating among competing inputs. OpenAI also introduced new enterprise plugins for ChatGPT Work that extend Astra's browser-use capabilities across common business applications, signaling a focus on integrating the model into routine enterprise software.
