Tesla is imposing a $200-per-week cap on employees' use of third-party AI tools, effective July 6, 2026. Spending above the limit requires manager approval, and the Grok beta from Elon Musk's xAI is exempt.

Tesla Puts a Leash on Runaway AI Bills
An internal memo caps employees' external AI tool spending at $200 per week from July 6, 2026. Some engineers had been burning through thousands of dollars in tokens weekly — a pattern now dubbed "tokenmaxxing."

Rolled Claude Code to ~5,000 engineers; blew full-year budget in 4 months, then set per-tool caps. 95% used AI monthly; 11% of backend updates fully agent-generated.
Microsoft
Scaled back Claude Code licenses amid high bills, shifted to GitHub Copilot CLI.
