General Motors will launch a proprietary in-vehicle artificial intelligence system for its U.S. vehicle lineup later in 2026 [1].

This move represents a strategic shift toward vertical integration of software. By developing its own assistant, GM aims to move beyond the limitations of third-party systems to create a more customized user experience.

The new system is designed to integrate OnStar services, vehicle telemetry, and predictive-maintenance data [2]. This allows the AI to provide real-time updates on the health of the vehicle, and personalized assistance based on the specific needs of the driver [2].

There are conflicting reports regarding the technical foundation of the system. Some reports suggest GM is building an assistant that goes beyond the capabilities of Google's Gemini [2], while other sources indicate the internal system may be powered by Gemini [3].

Further contradictions exist regarding the timeline and nature of the rollout. While GM plans to launch its proprietary system this year [1], other reports state the company will begin integrating Google's Gemini AI into its vehicles in 2027 [4].

These developments are part of a broader roadmap toward autonomous technology. GM has previously slated the arrival of its first eyes-off capable vehicle at dealerships for 2028 [5].

The company has not provided a detailed breakdown of which specific models will receive the update first, though it is expected to span the broader vehicle lineup [1].

GM plans to launch a proprietary in-vehicle AI system later this year.

GM is attempting to reduce its reliance on big-tech ecosystems like Google to own the primary interface between the driver and the vehicle. By controlling the AI layer, GM can monetize vehicle data more effectively and create a seamless link between hardware maintenance and digital assistance, which is a critical stepping stone toward the full autonomy planned for 2028.
