Microsoft is reshaping the economics of Copilot by making a deceptively simple wager: the best AI experience does not always require the biggest, most expensive frontier model. Instead, the company is increasingly routing everyday work to specialized in-house MAI models, while reserving top-tier...

Microsoft is reportedly testing Moonshot AI’s newly released Kimi K3 model for possible use in Copilot while preparing to offer the Chinese-developed system through Microsoft Foundry on Azure. The evaluation does not mean Kimi K3 is about to replace OpenAI technology across Microsoft’s AI...

OpenAI’s generally available GPT-5.6 family will become the preferred model powering Microsoft 365 Copilot, extending across Word, Excel, PowerPoint, Copilot Chat, and Cowork even as Microsoft reportedly deploys its own MAI models in parts of Word and Excel to control costs. The announcement is...

If you need to choose the exact AI model that handles your coding work, do not treat Copilot Free or Student as your long-term home: as of June 24, 2026, those plans are Auto-only for model selection, which means the practical choice is to accept GitHub’s routing or move to Copilot Pro, Pro+, an...

Microsoft is reportedly evaluating a fine-tuned DeepSeek model or another open-source alternative for parts of Copilot Cowork, even as the U.S. government restricts access to Anthropic’s Fable 5 and Mythos 5 models over national-security concerns tied to China and advanced cyber capabilities...
