General Motors confirmed this week that it will launch a proprietary, natively integrated in-vehicle artificial intelligence assistant later this year, a system designed to work alongside — not replace — the Google Gemini assistant GM began rolling out earlier in 2026. The disclosure came from Anna Santos, GM’s director of product management for voice services and artificial intelligence, in comments to CNBC that offered the company’s most detailed public description yet of a project it first previewed last October. Why a Second Assistant GM’s logic is straightforward: a general-purpose conversational AI, however fluent, was never built to see inside a car. Gemini can field an open-ended question, stream music, or adjust the cabin temperature, but it has no native line into a vehicle’s mechanical state, its sensors, or the patterns of a specific driver’s behavior over time. Santos framed the limitation as structural rather than a shortcoming of Gemini itself, noting there is a ceiling to what an assistant operating at the top layer of a vehicle’s software stack can actually do. GM’s answer is a second system built from the ground up on data the company already owns — OnStar telemetry, predictive maintenance diagnostics, and real-time mechanical readouts — paired with conversational AI capable of interpreting it in plain language. Santos described the arrangement as proprietary by design. The vehicle data underpinning the new assistant belongs to GM, and the company’s stated goal is to convert that data into the kind of deep, model-specific expertise a third-party assistant simply cannot replicate. What the Native System Can Do That Gemini Cannot The clearest illustration GM has offered is a single command it calls, informally, a “kids setting.” Where Gemini can adjust one vehicle function at a time — the radio volume, say, or the cabin temperature — GM’s proprietary assistant
