Tesla’s long-awaited Grok AI assistant appears closer to reaching vehicles, according to recent firmware analysis from prominent Tesla researcher “green.” While CEO Elon Musk mentioned months ago that xAI Grok would arrive in Tesla vehicles, new discoveries suggest the company is developing multiple customizable personalities for the AI assistant.
The timing aligns with Tesla’s preparation for its Robotaxi platform launch, suggesting that Grok’s integration represents a critical component of the company’s autonomous vehicle strategy. However, hardware limitations may prevent older Tesla models from accessing this feature entirely.
green says: “In-car grok also got new language tutor personality.”
Firmware analysis reveals Tesla is working on various personalities for Grok, allowing drivers to customize their AI interactions based on personal preferences. Discovered personalities include argumentative, assistant, conspiracy, doctor, meditation, motivation, romantic, storyteller, and therapist modes.
Tesla has also developed kid-friendly versions featuring storytelling capabilities and trivia games designed to entertain younger passengers during trips. Additionally, a language tutor personality has recently appeared in firmware updates, expanding Grok’s educational potential.
Unfortunately, Grok appears limited to vehicles equipped with AMD Ryzen infotainment computers, potentially excluding many older Tesla models. Majority of 2019 and earlier vehicles won’t receive this feature without an MCU retrofit, which Tesla doesn’t currently offer.
The transition to AMD chips began in 2021 for Model S and X vehicles, while Model 3 and Y conversions started toward the end of 2021. Means thousands of Tesla owners may find themselves unable to access Grok without hardware upgrades.
During a January livestream on X, Elon stated, “You’ll be able to talk to your Tesla and ask it anything,” highlighting Grok’s potential scope. While the AI assistant has begun appearing in recent firmware updates behind the scenes, Tesla hasn’t announced an official release timeline.
The gradual firmware integration suggests Tesla is conducting extensive testing before public deployment. With Tesla Robotaxi development accelerating and firmware evidence mounting, Tesla owners may soon discover that their vehicles have finally found their Grok – both literally and figuratively.
