Microsoft Unveils Advanced AI Features, Debuts Copilot Cowork

Microsoft on Monday unveiled major upgrades to its Copilot Cowork research assistant, allowing users to run multiple AI models simultaneously within the same workflow. The move marks the company’s latest effort to strengthen its AI ecosystem and drive wider adoption of Copilot. Under a new feature called “Critique,” Copilot’s Researcher agent will now generate responses using OpenAI’s GPT model and then send the output to Anthropic’s Claude model for review. While GPT drafts the response, Claude checks it for accuracy, quality, and potential errors before presenting it to users.

Microsoft plans to make the workflow bi-directional in the future, enabling GPT to review Claude-generated drafts as well.

Nicole Herskowitz, Corporate Vice President of Microsoft 365 and Copilot, told Reuters that integrating multiple AI models within Copilot offers customers the advantage of collaborative AI systems rather than relying on a single engine.

Tackling AI Hallucinations, Boosting Productivity

Microsoft says the multi-model setup will reduce AI hallucinations — instances where AI systems generate incorrect information — while improving response reliability and speeding up workflows. The company believes this approach will enhance productivity and output quality for enterprise users.

‘Council’ Feature Enables Model Comparison

In addition to “Critique,” Microsoft launched a new feature called “Council,” which allows users to compare responses from different AI models side by side. The feature gives customers greater transparency and control over AI-generated outputs.

Copilot Cowork Rolls Out to Frontier Members

Microsoft also expanded access to Copilot Cowork, its agentic AI tool, for members of its “Frontier” early-access program. The tool, inspired by Anthropic’s Claude Cowork product, focuses on autonomous AI agents capable of performing complex tasks.

The Windows maker continues to enhance Copilot as competition intensifies from rivals such as Google’s Gemini and other advanced AI agent platforms.

Microsoft’s shares rose about 1% on Monday. However, the stock remains on track for its steepest quarterly decline since the 2008 global financial crisis, falling nearly 25% amid cooling investor enthusiasm around AI.
