Meta and Microsoft push employees off Claude Code onto in-house tools

The Information reports that Microsoft and Meta are telling their own engineers to use less Claude, and the pressure is coming through spending caps and in-house tools rather than policy.

The outlet says Microsoft cut its per-employee monthly AI spending limit in its cloud and AI division from $100,000 to around $10,000 in most cases. It says Meta's Claude Code user count has moved from about 60,000 earlier this year to roughly 30,000, as the company pushes engineers onto its own Muse Code and the Meta-only MetaCode. Both companies still sell or distribute Claude to outside customers. The cuts apply inside the companies and do not change the Claude access those customers have.

What the limits look like

The Information frames the moves as cost control at a scale almost nobody else operates at. Microsoft, Meta and Amazon together are three of Anthropic's biggest customers, so a cut inside Microsoft from $100,000 to $10,000 per employee, or a halving inside Meta, is a visible change in the vendor's internal-usage pipeline, even without any customer-facing event.

Microsoft is doing this with the budget line: a smaller cap per head, with employees expected to spend more time with GitHub Copilot and OpenAI frameworks and less with Claude. Meta is doing it with the tool: engineers are being routed to Muse Code and MetaCode. Both routes end in the same place, which is less Claude inside each company's own build process.

What this does not mean for a buyer

A reader comparing Claude Code with GitHub Copilot or an internal agent should notice three limits on this story. First, these are internal choices by companies that build competing products: Microsoft owns GitHub Copilot, Meta owns Muse Code. A team outside those companies is making a different decision for different reasons.

Second, every figure in this item comes from one paywalled report; it has not been independently verified here, and Anthropic has not responded publicly to the specific numbers.

Third, both companies' public actions toward Anthropic point in different directions in parallel. Microsoft keeps selling Claude on Azure, and Anthropic's cloud presence is still expanding. The useful signal for a buyer sits inside those internal replacements. Microsoft and Meta are confident enough in Copilot and Muse Code to send their own engineers to them for daily work, which is a stronger evidence of maturity than a product page or a press release.
