GPT-6 Astra joins the frontier models available in Copilot Cowork and Copilot Studio, giving customers more choice for complex work they want to delegate to AI. Astra expands the range of work that can be handed off to Copilot. Instead of breaking work into smaller pieces and guiding it step by step, you can delegate larger tasks and focus your time on reviewing results, making decisions, and moving work forward. As more work is delegated, the quality of the outcome depends on both the model and the context it can reason over. Work IQ grounds GPT-6 Astra in your files, meetings, chats, and business data within existing permissions, resulting in more relevant and accurate responses.
