The Backstory

The history behind this event
Microsoft Launches Copilot Cowork and Dual-Model Review Features Using GPT and Claude2026-03-31 · 1 reports · similarity 0.85

Microsoft 365 Copilot previously relied primarily on OpenAI’s GPT, but Microsoft has now added Anthropic’s Claude. The move signals a shift in enterprise AI from reliance on a single model toward dividing work between models and having them review one another to reduce research errors. Copilot Cowork also advances the assistant into an agent capable of carrying out lengthy, multistep tasks across Outlook, Teams and files.

Microsoft made Copilot Cowork available through its Frontier program on March 30, 2026, before formally launching it worldwide on June 16. Critique uses Claude to review answers produced by GPT, while Model Council compares model responses side by side. The overall score across DRACO’s 100-task benchmark rose by 7.0 points. Microsoft 365 E7, launched on May 1, is priced at $99 per user per month.
