Microsoft shifts to in-house AI models to cut costs
Microsoft has begun reducing its reliance on third-party AI models from OpenAI and Anthropic by deploying its own in-house MAI models to handle a portion of user prompts in widely used Office apps such as Excel and Word, Bloomberg reported. The company also announced seven new MAI models at its recent Build conference, including an agentic coder and a text-to-image generator. Microsoft confirmed it had no further comment to TechCrunch. The move is presented as part of a broader industry cost-cutting trend, with other large firms including Amazon, Uber, Meta and Accenture also taking steps to curb AI spending; some companies are reportedly considering lower-cost Chinese models despite security concerns.
Microsoft (a major platform) reducing reliance on third-party models and deploying in-house models affects AI vendor economics, enterprise procurement, and model-sourcing strategies across the industry.

Microsoft unveils AI models to rival OpenAI, cut costs
At its Build developer conference in San Francisco on June 2, 2026, Microsoft announced new proprietary AI models aimed at reducing reliance on third-party providers like OpenAI and lowering developer costs. The company unveiled MAI-Code-1-Flash, a coding-focused model integrated into GitHub Copilot and Visual Studio Code, and MAI-Thinking-1, a medium-sized reasoning model offered in private preview via Microsoft Foundry. Microsoft highlighted efficiency and lower token costs as key benefits and also revealed updated cloud models for speech recognition, synthetic voice, image generation and small Aion models that can run on Windows PCs. Executives cited competitive positioning versus OpenAI, Anthropic and Google and emphasized running models on Azure to capture economic advantages. Microsoft has previously invested in OpenAI ($13 billion) and Anthropic ($5 billion).
Microsoft Trains Sales to Undercut OpenAI, Anthropic
Microsoft held an internal strategy meeting instructing its sales team to present Microsoft’s own AI models as more efficient, cost-effective and better integrated than rivals, according to a Bloomberg report cited by TechCrunch. Executive Vice President Jay Parikh framed Microsoft as offering a full end-to-end system, while Executive Vice President Jacob Andreou compared Microsoft’s Copilot to Anthropic’s Claude, saying Claude was slower, less accurate and lacked security integrations. The move follows reports that Microsoft has been replacing OpenAI and Anthropic models in flagship apps like Word and Excel with its own models as a cost-cutting measure, and comes after the companies amended Microsoft’s partnership with OpenAI in April to remove exclusivity.
Microsoft openly competes with OpenAI, Anthropic
Microsoft signalled a more explicit competitive posture toward OpenAI and Anthropic during its fiscal-quarter earnings call, arguing enterprises should use multiple models and keep the agentic "harness" separate from models. The company reported a blockbuster quarter — $90 billion in revenue and $35.8 billion in net income, and $331.8 billion revenue with $133.7 billion net income for the fiscal year ending June 30 — and framed that success as leverage to sell its own models, agents and silicon. CEO Satya Nadella promoted Microsoft’s MAI model family and Maya chips (citing a 40% performance-per-watt gain on Maya 200) and announced MAI Cyber One Flash as a competitor to larger frontier models. Nadella referenced a recent Hugging Face security incident to argue against relying on a single frontier model.
