Tesla AI Senior Staff Engineer Yun-Ta Tsai confirmed the company uses xAI’s Grok to develop Full Self-Driving (FSD) and the upcoming Cybercab. This marks the first time a named engineer has detailed the depth of Grok’s integration into active vehicle software. The disclosure moves the project from high-level conceptual plans to confirmed engineering applications.
The integration adds weight to Tesla’s AI-centric strategy, which remains a primary focus for long-term valuation. While CEO Elon Musk previously signaled Grok’s future involvement, this confirmation indicates deeper technical development is currently underway.
U.S. markets were closed for Memorial Day, resulting in no immediate stock price reaction. The news reinforces the bull case for Tesla as a robotics and AI firm, alongside its FSD rollout and Optimus robot progress. Tesla has not announced an official timeline for the public release of Grok-integrated FSD.
