Microsoft launches new in-house AI models it says cut costs up to 89% versus OpenAI - VentureBeat

Microsoft has finally done it—launched its own AI models, MAI-Image-2.5-Pro and MAI-Voice-2-Flash, into public preview, claiming they cut GPU costs by up to 84% compared to OpenAI's equivalent. That's right: the company that has pumped billions into OpenAI, that has Azure exclusively hosting OpenAI models, that practically strapped itself to the OpenAI rocket, is now selling a cheaper knock-off. Fun fact: this is the same Microsoft that recently said it would 'deepen' its partnership with OpenAI. Deepen, as in, from the front while stabbing from behind.

The numbers are, if true, impressive: 84% less GPU cost for images, up to 89% overall cost reduction versus OpenAI. But let's not pretend this is altruism. This is Microsoft hedging. If OpenAI goes rogue—and we've seen the headlines about 'rogue' AI systems—Microsoft wants its own lifeboat. Plus, these are 'public preview' models, which means they're essentially beta tests for enterprise customers who are tired of paying OpenAI's GPU-tax. It's a beautiful two-step: fund the dominant player, then undercut them with your own version.

What does this mean for the frontier? Microsoft is now both the largest investor in OpenAI and a direct competitor. The arrangement that made CEO Satya Nadella look like a genius now looks like a divorce lawyer's dream. Meanwhile, every customer who signed a long-term Azure deal is wondering if they should wait for the next Microsoft model. The gall is spectacular—but at least the prices are down. Cheers to progress, eh?
