Meta spends hundreds of millions on Microsoft's AI services

According to Bloomberg, Meta has become one of Microsoft's largest AI customers, spending hundreds of millions of dollars on Microsoft's AI services. The report does not specify which Microsoft AI products are involved.

Why it matters: Meta has poured tens of billions into its own AI infrastructure and Llama models, yet it's still a major buyer of a rival's AI services, suggesting even the best-resourced labs can't build everything in-house. It echoes Stripe's reported rationale for buying OpenRouter and Ramp's new AI model router: companies are increasingly hedging across multiple AI providers rather than betting on one stack.
