Microsoft and Meta Shift Employees from Anthropic AI to In-House Tools

Microsoft and Meta are increasingly shifting their employees away from using Anthropic’s Claude AI tools in favor of their own in-house solutions. According to a report by The Information, Microsoft was on track to spend $1 billion this year on Anthropic’s technology but has since reduced that figure by one-third. The company has been encouraging staff to use its GitHub Copilot coding tool instead of Claude Code, Claude models in Microsoft’s Copilot, and Claude Mythos.

Meta has also significantly cut down on its use of Anthropic’s Claude Code, reducing the number of employees using the tool from 60,000 earlier this year to 30,000. The company is pushing employees to use its competitors, Muse Code and MetaCode, according to the report. Meta had been planning to spend billions on internal AI tools, with Claude Code being the most popular option.

The Wall Street Journal reported that companies are struggling to forecast AI spending accurately, with only 11% of nearly 400 surveyed businesses able to project their AI costs correctly. The Ramp AI Index found that the top 1% of U.S. businesses spent a median of $7,400 per employee on AI in July, while the median company spent just $11.95 per employee. Anthropic leads overall business adoption, with 43.5% of U.S. businesses paying for its subscriptions or tokens as of July.
