Tesla has recently rolled out its latest software update, version 2025.26, for eligible vehicles in the United States. A standout addition in this update is the introduction of Grok (beta), a conversational AI chatbot developed by xAI – Elon Musk's artificial intelligence company. This AI tool is now accessible in Tesla vehicles equipped with AMD Ryzen infotainment systems, though it requires either premium connectivity or Wi-Fi access to function. Earlier this week, CEO Elon Musk officially announced plans to integrate Grok into Tesla's vehicle ecosystem. It is important to note that in this initial beta phase, Grok operates exclusively on infotainment displays, enabling both drivers and passengers to engage in general conversations. However, the chatbot currently lacks the capability to execute vehicle-specific voice commands such as climate control adjustments, navigation settings, or glovebox operations. This means Grok will not replace or interfere with Tesla's existing voice command system (at least for now). While Grok's functionality remains limited, its implementation signifies the growing significance of generative AI within Tesla's technological ecosystem. Unlike traditional voice assistants such as Siri or Alexa, Grok is built on large language models (LLMs) similar to OpenAI's ChatGPT and Google's Gemini, enabling more natural and open-ended conversations. Even in its early form, this integration makes Tesla one of the first major automakers to embed a conversational AI chatbot directly into vehicles. Musk has hinted at full integration in the future, where AI chatbots could respond to natural language inputs and directly control vehicle functions. This isn't the first time xAI's Grok has expanded into Musk's ventures. Notably, Grok has already gained popularity among X (formerly Twitter) users. Recently, xAI released Grok 4, which represents a significant upgrade over its predecessor Grok 3. A key highlight of this version is "Grok 4 Heavy," an advanced model architecture designed to operate multiple AI agents collaboratively, enhancing accuracy and reasoning capabilities – particularly for complex tasks. In addition to Grok integration, Tesla's 2025.26 software update introduces several other enhancements aimed at improving user experience. One notable feature is Light Sync, which enables interior lighting to react to music and reflect album cover colors. This is available only on newer models including the latest Model 3, Model Y, and 2026 versions of Model S, Model X, and Cybertruck. The EV giant also introduced custom audio presets, allowing users to save multiple EQ and sound settings. Additionally, the dashcam viewer now features zoom and playback speed controls with a new grid view for Cybertruck footage. The update further improves charging information by displaying whether a location requires valet access, paid entry, or access codes. It also provides detailed on-site information such as restroom locations and floor levels. A new introductory guide helps new owners learn essential functions including lighting, wipers, doors, and autonomous driving features. Like all Tesla software updates, version 2025.26 will be distributed over-the-air through a phased rollout. Eligible vehicles will automatically receive the update when connected to Wi-Fi or using premium connectivity. This update arrives at a critical time for Tesla, which is currently experiencing significant sales declines. Early this month, the company reported consecutive second-quarter global vehicle delivery drops. In Q2 2025, the EV leader delivered 384,122 vehicles, representing a 13% year-over-year decrease.
