GPT-5 Prompts Cut Work Time with Copilot
Microsoft is integrating OpenAI's GPT-5 into its Microsoft 365 Copilot and GitHub Copilot, enabling prompts to automate end-to-end workflows from competitive analysis to expense reporting. Satya Nadella shared five prompts illustrating tasks like meeting preparation, project updates, time analysis, and briefing, highlighting GPT-5’s seamless fit across Microsoft apps. The article notes that ChatGPT with GPT-5 is evolving into a central assistant capable of orchestrating multi-step tasks, aided by OpenAI’s agent mode which can connect to Gmail, Notion, Slack, and other tools. Forbes reports that using these prompts can save over 10 hours per week, with additional AI adoption insights from Microsoft and Civey. The piece also emphasizes the need for human oversight in critical steps and mentions OpenAI’s broader push to position AI as a central access point to the web via Mega-KI.

GPT-5.6 becomes preferred model in Microsoft 365 Copilot
OpenAI announced during the GPT‑5.6 launch that GPT‑5.6 will be the “preferred model” powering Microsoft 365 Copilot across productivity apps including Word, Excel, PowerPoint, Copilot Chat and Cowork. OpenAI published a blog post saying GPT‑5.6 will support Microsoft users across the suite; Microsoft will serve the model natively in Copilot experiences and can also access it via the OpenAI API. The disclosure follows Bloomberg reporting that Microsoft has been increasing use of its own in‑house models (MAI) to cut costs, which sparked coverage questioning whether the two companies were drifting apart. OpenAI’s announcement frames the move as a continuation of the partnership, but it did not fully define what “preferred model” entails and does not appear to negate prior reports that Microsoft is also deploying its own models to reduce expenses.
Copilot Cowork: AI Handles Microsoft 365 Tasks
Microsoft is expanding its 365 Copilot with Copilot Cowork, an AI feature that can automatically generate and execute work plans across Outlook, Teams, and Excel. It analyzes data from emails, files, meetings, and documents, creating milestones, tracking progress, and requesting decisions as needed. Copilot Cowork aims to move beyond chat-style support to autonomous task execution, using a system called Work IQ to orchestrate workflows across apps. The solution can prepare briefs, presentations, and analyses for meetings and product launches, and can perform enterprise research and financial analyses. It is currently being tested with select customers, with wider availability planned for the end of March 2026 via the Frontier program. The article also notes Microsoft’s broader use of multi-model AI, including Claude from Anthropic, within Copilot Studio and related tools, all operating under Microsoft 365 security and governance controls.
Microsoft unveils unified Copilot app to challenge Anthropic
Microsoft is updating its Copilot app for corporate workers, combining coding capabilities with agent-building tools in a single application. The move aims to challenge Anthropic's Claude and attract more Office 365 customers to pay for advanced AI features. The new app includes Home, Code, and Autopilot tabs, with usage-based pricing for the Code and Autopilot parts. Less than 7% of the 450 million commercial Office 365 seats currently have AI licenses, indicating slow adoption. The updated app allows users to select from various AI models, including OpenAI's and Anthropic's, as well as Microsoft's own cost-efficient offering. The company faces competition from Meta's Muse app and other AI agent tools. Microsoft's stock has underperformed most megacap peers this year.
