Microsoft усиливает конкуренцию с OpenAI и Anthropic: свои AI-модели и агенты

Microsoft on July 29, 2026 presented Wall Street with its own AI models, agent harnesses, and even a competitor to the Mythos product — a signal that the company is increasingly openly competing with its partners OpenAI and Anthropic.

What Microsoft showed

Microsoft rolled out three classes of its own AI developments at once: language models, harnesses (frameworks for running AI agents), and a direct competitor to the Mythos product. This was reported by TechCrunch on July 29, 2026, following the company's discussion with investors.

*Announcement date — July 29, 2026

*Microsoft's own language AI models

*Agent harnesses — frameworks for running and orchestrating agents

*A competitor to the product called Mythos

*Audience — Wall Street, with a message about continued growth

Microsoft presented this as part of a strategy for further growth, not as a one-off experiment. Betting on its own stack — from base models to agent infrastructure — means the company wants to own the entire chain, not just the storefront in the form of Copilot.

The presentation took place amid discussions with investors about business results: Microsoft tied its own AI developments to a promise to continue growing and made clear that it sees AI as its own source of revenue, not just a cost item tied to partners.

What an agent harness is

An agent harness is software wrapping that turns a language model into an acting agent: it gives it tools, memory, access to a browser and code, and manages the "thought — action — verification" loop. On July 29, 2026, Microsoft for the first time showed investors its own such harness, not just models.

Control over this layer is critical for enterprise scenarios — from Copilot to workflow automation. Whoever owns the harness determines which models and tools get plugged in under the hood, and this is exactly where Microsoft wants to stop depending on someone else's solutions. The fight is not for a single model, but for the entire layer built on top of it.

Why this matters for OpenAI and Anthropic

Microsoft simultaneously remains a key partner and is becoming an increasingly overt competitor to both labs. The company has spent years integrating other companies' models into its products and investing in OpenAI, but now it is publicly showing that it is building its own alternative — down to a competitor to the specific Mythos product.

For OpenAI and Anthropic, this means that the largest distributor of their technologies in the enterprise segment is turning into a direct rival. The more Microsoft relies on its own models and harnesses, the lower its dependence on partners becomes — and the fiercer the fight for the same corporate AI budgets.

Copilot and Microsoft 365 corporate subscriptions are the main channel through which businesses gain access to cutting-edge AI. If Microsoft's own models end up under the hood of this channel instead of OpenAI's, the balance of power in the enterprise-AI market could shift faster than analysts expected.

"Microsoft unveiled its own AI models, harnesses, and even a competitor to Mythos,"

TechCrunch's July 29, 2026 report states.

What this means

Microsoft's pivot from the role of "partner-distributor" to independent player is accelerating: on July 29, 2026, the company for the first time so openly showed Wall Street its bet on its own AI stack. For the market, this is a signal that the line between allies and competitors in AI is finally blurring, and enterprise customers will have to choose not between "Microsoft and OpenAI," but between Microsoft's stack and everyone else. The coming quarters will show how quickly Microsoft replaces other companies' models with its own inside its own products.
