Tesla is preparing to introduce its most advanced in-car assistant yet: Grok, a conversational AI built on xAI’s large language model. First revealed through a firmware teardown and recently uncovered user interface images, the Grok assistant is embedded in Tesla software version 2025.20 and is expected to be activated in an upcoming update—likely version 2025.24.
Unlike the current voice command system in your Tesla , which is functional but rigid, Grok offers a rich, natural-language interface that responds to both typed and spoken input. The assistant appears as a floating window in the lower-left corner of the center display, according to images of the user interface (UI) shared by hacker @greentheonly.
Grok in your Tesla will also support customizable voices and personalities, like the mobile app. Drivers can choose from three voices—Ara (an upbeat female), Rex (a calm male), and Gork (a mellow male)—as well as over a dozen distinct personalities.
These include practical modes like Assistant, Therapist, Meditation Guide, and Language Tutor, alongside more niche options such as Storyteller, Romantic, Argumentative, and even a “Grok Classic” mode that embraces a more unfiltered, edgy tone. There are even child-friendly personas designed for storytelling and trivia during road trips.
Grok isn’t just a gimmick—it’s integrated into Tesla’s broader vehicle control architecture. Over time, it’s expected to replace the current command system entirely, allowing users to speak casually to adjust mirrors, set navigation, control media, or change the cabin temperature.
The goal is to create a more seamless, human-like interaction that adapts to each driver’s style and needs.
To use Grok, it appears as though Tesla owners will need a vehicle equipped with the AMD Ryzen infotainment processor. Older Intel-based systems will not support the feature, although support may be introduced a later date, as has been done with features. In addition, Grok requires either a Premium Connectivity subscription or a Wi-Fi connection, as well as an xAI-linked login via QR code scanning. This suggests the assistant will rely on cloud processing, at least in part, to deliver its full functionality.
Currently, Grok is already in place but dormant within compatible firmware, and Tesla can remotely activate it with the switch of a button—meaning no major download will be required once the rollout begins. With the groundwork already in place and this level of development and access for internal testers, Grok’s official activation appears imminent, possibly as part of a larger Summer Update.
