GPT-6 Astra Rolls Out Across Microsoft’s AI Platforms
Microsoft Begins Integrating OpenAI’s GPT-6 Astra Across Copilot and Azure Services as the New Model Expands Access to More Advanced AI Capabilities.
OpenAI’s GPT-6 Astra is expanding across Microsoft’s AI ecosystem, giving businesses access to the company’s latest frontier model through products including Microsoft Copilot and Microsoft Foundry. The rollout is part of a broader effort to make more capable AI systems available for complex professional and enterprise tasks.
Microsoft says Astra is designed to handle larger, more complicated assignments rather than simply responding to individual prompts. In Copilot Cowork and Copilot Studio, users can delegate broader tasks to the model and focus more on reviewing its results, making decisions and directing the overall work.
Astra is also available through Microsoft Foundry, where developers and organisations can integrate the model into AI applications and workflows. Microsoft highlights capabilities including reasoning, computer use, tool calling, structured outputs and multi-agent orchestration, while the model supports a context window of more than one million tokens.
The expansion comes shortly after OpenAI introduced Astra as its newest frontier model, promoting improvements in areas such as software engineering, scientific work and complex digital tasks. However, the rollout has been gradual, with some users experiencing delays as OpenAI manages capacity, safety controls and access across different customer groups.
The Microsoft integration could significantly broaden Astra’s role in workplace AI, particularly as companies increasingly use AI systems to handle multi-step tasks. Microsoft says availability can vary by region and organisation, meaning access will depend on the specific Copilot or Foundry environment and administrator settings.
