Microsoft stock rises 3% on push for in-house AI models

May 28, 2026 10:20 AM

Investing.com -- Microsoft (NASDAQ: MSFT) shares rose 3% Thursday after The Information reported the company plans to release a new coding model next week as part of a broader push to reduce dependence on external AI partners.

The report said Microsoft will unveil a suite of in-house AI models at its Build developer conference in San Francisco. The lineup includes a coding model designed to help GitHub Copilot better compete with rivals like Cursor and Claude Code, along with other models specializing in reasoning, speech, transcription, and image generation.

Microsoft currently relies heavily on models from OpenAI, which it receives at no cost until 2032, and Anthropic to power its software. The company aims to build its own competitive AI capabilities to avoid dependence on expensive outside suppliers when its OpenAI agreement expires.

According to the report, Microsoft’s internal AI team, led by AI chief Mustafa Suleyman, was previously restricted from training top-tier AI models due to its deal with OpenAI. Those restrictions were renegotiated in April, enabling development of the new models.

Microsoft plans to market the new models as cheaper alternatives to the slightly more capable models from OpenAI and Anthropic. The strategy is also expected to help Microsoft lower costs of running AI features within its Office applications.
