Meta halves internal Claude Code seats to ~30,000 after $105M monthly bill

Meta has reduced internal access to Anthropic's Claude Code from roughly 60,000 seats to about 30,000. The trigger was cost: internal reports show over $105 million spent across a single 28-day billing cycle on external coding model endpoints.

The directive pushes engineering teams to move primary developer workflows onto Meta's internal Llama infrastructure and proprietary assistants. That is both a cost play and a strategic one: Meta wants its own models battle-tested by tens of thousands of in-house engineers.

The numbers are a rare public view into what frontier coding agents cost at scale. A run rate above $1.2B a year for one company's internal use shows why Anthropic's enterprise revenue has grown so quickly, and why big customers are now looking to claw it back. Enterprise leads in community threads say unstable API behavior and deprecations make token budgeting hard.

Caveats: even after the cut, 30,000 engineers still rely on Claude, which suggests Llama is not yet a full substitute for frontier coding. Watch whether Meta's spend actually falls, and whether other large Anthropic customers follow with similar caps.
