Microsoft is reportedly ditching OpenAI’s and Anthropic’s AI models in favor of its own to cut costs
Why it matters
Microsoft's shift from third-party frontier models to proprietary MAI signals a major recalibration of AI economics: either the cost-per-inference math has fundamentally changed, or Microsoft believes it can undercut OpenAI/Anthropic on price while maintaining acceptable quality. This reshuffles the entire inference market and threatens OpenAI's enterprise moat.
Key signals
- Microsoft transitioning from OpenAI and Anthropic advanced models to Microsoft AI (MAI) family
- Primary driver: cost reduction
- Microsoft publicly claims MAI is less sophisticated than frontier models, yet still deploying it at scale
- Signals major shift in AI vendor economics and customer acceptance of 'good enough' models
- Potential impact on OpenAI and Anthropic enterprise revenue and inference margins
The hook
Microsoft just made a $10B+ strategic bet. They're ditching OpenAI and Anthropic models — and building their own instead.
Microsoft Corp. is reportedly transitioning away from using OpenAI Group PBC’s and Anthropic PBC’s most advanced artificial intelligence models in favor of its own — increasingly leaning on the new Microsoft AI or MAI model family, despite publicly asserting that those models aren’t as sophisticated as other leading frontier AI systems. That’s according to a […]
