# Microsoft Openly Competing with OpenAI and Anthropic with Homegrown Models

> Microsoft is dropping the pretense of being merely OpenAI's biggest backer. Satya Nadella used the company's latest earnings, which showed 90 billion dollars in quarterly revenue, to lay out an openly competitive stance against both OpenAI and Anthropic, pushing Microsoft's homegrown MAI model family as a cheaper alternative to the partners it has poured billions into. The pitch leans on efficiency. Microsoft claims the MAI models deliver around 40 percent better performance per watt than rivals, and it has shipped a security-focused model, MAI-Cyber-1-Flash, priced at half the cost of comparable larger systems. Alongside its own models, the company is offering more than 11,000 models through its cloud, positioning itself as the neutral marketplace rather than a single vendor's storefront. The strategy is really about reducing dependency, both its own and its customers'. By building in-house and reselling everyone else, Microsoft hedges against any one lab's pricing or missteps. For OpenAI, watching its largest investor turn into a direct competitor is a reminder that in this market, today's partner is tomorrow's rival.
