Microsoft and Meta cut staff use of Anthropic Claude for in-house tools
Microsoft and Meta are reducing their reliance on Anthropic’s AI tools in favor of internal alternatives. Microsoft, which was on track to spend $1 billion on Anthropic technology this year, has lowered that figure by one-third. A spokesperson confirmed the company is steering staff toward GitHub Copilot, though engineers retain the option to use other models. The shift affects tools including…
Key points
- Microsoft lowered its projected $1 billion Anthropic spend by one-third, steering staff to GitHub Copilot.
- Meta reduced Claude Code users from 60,000 to 30,000, promoting in-house tools Muse Code and MetaCode.
- Anthropic leads U.S. business adoption with 43.5% of companies paying for its subscriptions or tokens.
Meta has similarly halved its internal usage of Anthropic’s Claude Code, dropping from about 60,000 employees earlier this year to 30,000. The company is pushing staff to use its competitor, Muse Code, and its in-house-only tool, MetaCode. Meta did not comment on the report, which originally appeared in The Information.
These moves occur against a backdrop of uncertainty in AI spending forecasts. A Wall Street Journal report noted that only 11% of nearly 400 surveyed businesses could accurately project their AI costs. Data from the Ramp AI Index shows significant disparities in spending, with the top 1% of U.S. businesses spending a median of $7,400 per employee on AI in July, compared to $11.95 for the median company. Despite the internal shifts at major tech firms, Anthropic remains the leader in overall business adoption, with 43.5% of U.S. businesses paying for its subscriptions or tokens as of July.
