Meta pays Microsoft hundreds of millions a year to rent AI models
Meta reportedly spends hundreds of millions annually on Microsoft's Azure for AI model access, making it one of Microsoft's largest AI customers. Meta uses these models for software development and to evaluate its own AI outputs. Both companies declined to comment. Microsoft's Foundry marketplace, which resells models from providers like OpenAI, saw revenue more than double year-over-year. Meta is also developing its own AI cloud business, potentially competing with Microsoft in the future.
