Meta Quietly Emerges as Microsoft’s Major AI Customer
Meta is using Microsoft’s computers and AI models to help build its own technology.
It reportedly spends hundreds of millions of dollars each year for this access.
Meta also uses trillions of small AI-computing units called tokens every week.
Microsoft sells access to different AI models through a service called Foundry.
Many of Foundry’s biggest customers are technology companies rather than traditional businesses.
Meta uses outside models to help developers and test its own models.
Meta is also creating a service that could sell access to AI models.
That service might eventually reduce Meta’s need for Microsoft’s services.
Meta reportedly spends hundreds of millions of dollars annually accessing AI models through Microsoft Azure.
Meta uses trillions of AI-computing tokens each week through Microsoft’s platform, according to a source.
Microsoft Foundry had 100,000 customers as of July, but its biggest customers are largely technology companies.
ByteDance is generally Foundry’s biggest spender, with Adobe, Perplexity and Sierra also identified as major customers.
Meta uses external models while developing its own and is building an API service that could compete with Foundry.

Concerns and Risks
Business and Development Rationale
Concentration of AI demand
Concerns and Risks
The report raises concerns that AI revenue and usage remain concentrated among sophisticated technology companies, creating dependence on a small group of customers.
Business and Development Rationale
Microsoft’s marketplace had 100,000 customers, and the company promotes use by industries such as manufacturing and transportation, even though its largest customers are currently technology firms.
Meta’s reliance on external models
Concerns and Risks
Meta’s substantial spending on external models could increase its dependence on Microsoft and other providers.
Business and Development Rationale
Meta uses multiple platforms based on availability and cost, while also developing its own models and using outside systems to assess their performance.
Potential competition with Microsoft
Concerns and Risks
Meta’s planned API service could compete with Microsoft Foundry and reduce Meta’s purchases from Microsoft.
Business and Development Rationale
The planned service would let Meta sell access to various AI models, potentially giving it another business while it continues using external services during development.
