Tesla's 2025.26 Software Upgrade Introduces Advanced AI Capabilities and Further Features
Tesla has taken a significant step forward in the realm of in-car technology with the introduction of Grok 4, a next-generation conversational AI. The AI chatbot, which is currently in beta, will only be available in the U.S., limited to Tesla vehicles equipped with AMD Ryzen infotainment chips.
Elon Musk, Tesla's CEO, announced the arrival of Grok 4 during a recent event, stating that it would be coming to cars "next week at the latest." The update, version 2025.26, marks Tesla's most substantial update this year and introduces Grok 4 as an in-car debut.
To access Grok 4, users can find it under the App Launcher > Grok or by pressing and holding the voice button on the steering wheel. A Wi-Fi connection or Premium Connectivity is required to use Grok (Beta).
Grok 4 offers a range of personalities, from the storyteller to more unhinged characters, allowing varied interaction styles. Conversations with Grok are anonymous and not recorded in connection with the vehicle. While Grok can chat intelligently, it does not have control over vehicle functions at this stage. Its reliability and ability to interact with the car are expected to improve over time.
In addition to the in-car integration, Grok 4 features specialized AI "companions," such as anime-themed avatars and other characters with distinct personalities. These companions add a personalized and sometimes provocative dimension to interactions with Grok, setting it apart in the current AI chatbot landscape. Notable characters include "Ani," an anime bot with a sexualized design, and "Bad Rudi," a vulgar red panda character.
The update also brings improvements to the user experience. New drivers of the Model 3 and Model Y will find an Onboarding Guide in the Service section, offering tutorials on touchscreen controls, driver profiles, and steering wheel functions. An upgraded Dashcam viewer is added, featuring zoom, playback speed control, and a grid-view interface for Cybertruck owners.
Moreover, Light Sync is introduced for the new Model 3, Model Y, 2026 Model S/X, and Cybertruck. This feature allows accent lights to pulse with music or match album colors, enhancing the overall in-car experience. Tesla has also improved the Supercharging experience with arrival-based notifications detailing parking rules, access codes, charger locations, and restroom availability.
However, there's no word yet on when Grok will be available to Tesla owners in Canada or other regions. Existing voice commands remain unchanged in the update. Users can sign in and sync their history across devices or interact in guest mode without an account.
In summary, the Grok 4 update in Tesla cars brings advanced conversational AI features accessible through voice and app interface, requiring specific hardware and connectivity. With evolving capabilities, distinctive AI character companions, and a range of personalities, Grok 4 represents a significant improvement over its predecessor and sets a new standard for in-car AI interactions.
Smartphone users can now connect with Grok 4, the advanced in-car AI, via Bluetooth for hands-free conversations, as the AI now supports tethered smartphone functionality. In addition to this, gadget enthusiasts can now add more smartphones to their Tesla vehicles' App Launcher, further enhancing the in-car technology experience offered by the brand.
