Woofun AI reports that Tesla will enforce a $200 weekly spending limit on employee AI tool usage beginning July 6, with any expenses exceeding this threshold requiring manager approval. While Elon Musk's xAI assistant Grok is exempt from this restriction, internal adoption remains low as most staff prefer Anthropic's Claude. Tesla previously announced plans to integrate Grok into vehicle infotainment systems in select European markets, though Musk clarified that the tool currently lacks control over vehicle functions.
