[Meta Uses Trillions of Tokens Weekly on Azure, Becoming One of Microsoft's Largest AI Customers] Jin10 News, August 20 – According to a source familiar with the matter, Meta Platforms (META.O) spends hundreds of millions of dollars annually accessing artificial intelligence models through Microsoft's Azure cloud services. Meta uses trillions of tokens weekly via this platform. Both companies declined to comment. A key pillar of Microsoft's AI strategy is offering models from multiple vendors through a marketplace called Foundry, which had 100,000 customers as of July. Customers from traditional industries such as manufacturing and transportation often appear in Microsoft's promotional materials. However, according to the source, most of its largest AI customers are still other tech companies. ByteDance, Adobe, Perplexity, and AI startup Sierra are also major Microsoft customers. The source revealed that Meta is making significant investments in AI to assist its software development, purchasing model access across multiple platforms based on availability and cost. Meta's developers have previously used OpenAI technology via Foundry to help evaluate the output of its own models.
