Tesla's 2025.26 Software Update Introduces AI Assistant Grok
Tesla has rolled out its latest software update, version 2025.26, which introduces several new features, most notably the in-car debut of Grok, Tesla's AI assistant developed by Elon Musk's xAI company.
Grok AI is now integrated into Tesla vehicles (initially limited to the U.S.) running on AMD Ryzen processors, including Model S, Model X, Model 3, Model Y, and Cybertruck. It functions as a conversational AI chatbot but does not replace the existing voice command system for vehicle controls.
Key new features of the 2025.26 update include:
- Grok AI Assistant (Beta): This is the first official rollout of Grok inside Tesla cars, supporting conversational AI interactions with a colorful sound-wave interface. Grok requires Premium Connectivity and is only available in the U.S. via AMD Ryzen-equipped vehicles. It does not control vehicle functions, which still rely on legacy voice commands.
- Light Sync: A new lighting feature that synchronizes interior or exterior lights with audio and other stimuli for an enhanced experience.
- Audio Presets: Ability for users to create and save customized audio settings for convenience and personalization.
- Improved Dashcam Functionality: Enhanced dashcam functionality, including zoom, playback speed control, and a grid-view interface for Cybertruck owners.
- Supercharger Arrival Info: Tesla has improved the Supercharging experience by providing detailed arrival-based notifications about parking rules, access codes, charger locations, and restroom availability.
Grok 4 represents a significant improvement over its predecessor in terms of reasoning, speed, and conversational ability. Conversations with Grok are anonymous to Tesla and are not linked to the user or the vehicle.
In addition to these updates, Tesla has also introduced Light Sync for the new Model 3, Model Y, 2026 Model S/X, and Cybertruck. The update includes improved audio customization, allowing users to create and save multiple audio presets.
Users can sign in and sync their Grok history across devices or interact in guest mode without an account. They can choose from multiple Grok personalities and voices, such as "Storyteller" or "Unhinged." Grok can be accessed through the App Launcher > Grok or by pressing and holding the voice button on the steering wheel.
However, it's important to note that the availability of Grok outside of the U.S. (Canada and other regions) has not been announced yet.
In summary, the highlight of Tesla's 2025.26 update is the introduction of Grok 4 AI in-car, providing an intelligent conversational interface without replacing existing vehicle voice controls, alongside experiential upgrades like Light Sync and audio preset customization.
- The 2025.26 software update from Tesla introduces Grok 4 AI, a conversational AI assistant, into their vehicles equipped with AMD Ryzen processors, such as Model S, Model X, Model 3, Model Y, and Cybertruck, marking the first official deployment of this technology within Tesla cars.
- With the 2025.26 update, Tesla's artificial-intelligence-powered Grok assistant can be found among the latest technology advances in smartphones and various gadgets, further showcasing the incorporation of AI in everyday devices.
