The two companies are taking steps to reduce employee usage of Claude, the AI assistant built by Anthropic, according to reports. Meta's internal use of Claude Code, Anthropic's coding tool, has reportedly halved.
The moves matter because Meta and Microsoft are among the largest corporate buyers of AI tools. When they pull back on a rival's assistant, it signals how quickly internal AI loyalties can shift—and how much weight a single vendor decision carries across the industry.
Meta's Claude Code usage reportedly halves
Meta has moved to limit how much its staff rely on Claude, and the reported drop in Claude Code usage is the clearest sign of that pullback. Claude Code is Anthropic's assistant aimed at software developers, a category where adoption is easy to measure because the tool sits inside everyday engineering work.
Reports describe the change as a deliberate internal step rather than a technical failure or outage. Neither Meta nor Anthropic has publicly detailed the reasons behind the reduction.
Microsoft limits Claude access for employees
Microsoft is also implementing measures to cut back on employee use of Claude. The company already offers its own AI assistants to staff, which gives it a natural alternative to push internally.
Both companies have their own AI products and partnerships to protect, so steering employees toward in-house tools is a familiar pattern in enterprise software.
Why the enterprise AI shake-up matters
The pullback comes as companies weigh cost, data control and vendor dependence in their AI choices. Pushing staff toward an internal assistant can reduce spending on outside subscriptions and keep more work inside a company's own systems.
