Tesla will implement a $200 weekly cap on employee spending for AI tools starting July 6, according to an internal memo. Any expenditure exceeding this limit will require supervisor approval. This move aligns with similar measures adopted by other U.S. tech firms. Notably, the use of the Grok model from Musk's xAI is exempt from this cap, although it reportedly has low adoption among Tesla employees, who prefer using Anthropic's Claude.
