Microsoft was on track to spend $1 billion this year on internal use of Anthropic’s technology, but it has since lowered that figure by one-third. The Anthropic tools include Claude Code, Claude models in Microsoft’s Copilot and Claude Mythos, according to the report.
A Microsoft spokesperson said in the report that the company has been steering staff to use its GitHub Copilot coding tool, although engineers can still choose to use other models, per the report.
Meta has reduced the number of its employees using Anthropic’s Claude Code from about 60,000 earlier this year to 30,000, largely by pushing them to use its Claude Code competitor, Muse Code, and its in-house-only tool MetaCode, according to the report.
