GM Wants an AI That Knows the Car, Not Just the Playlist
General Motors says a native in-vehicle AI assistant arrives later this year, layered under Google Gemini and wired into OnStar, vehicle telemetry, and proprietary car knowledge.
DETROIT — Google Gemini can change the radio. General Motors wants an assistant that can explain the wrench light.
On July 31, Anna Santos, GM’s director of product management for voice and AI, told CNBC the company will launch a proprietary in-vehicle AI assistant later this year. The system is meant to sit deeper than Gemini: conversational AI plus GM vehicle knowledge plus OnStar intelligence, aimed at jobs a general-purpose assistant cannot see from the top of the stack.
That framing matters. Gemini is already rolling into eligible model-year 2022 and newer Cadillac, Chevrolet, Buick, and GMC vehicles with Google built-in. GM’s April newsroom post put the U.S. eligible pool at about four million vehicles, one of the largest Gemini deployments in the industry, delivered over months as an over-the-air upgrade. Gemini handles natural conversation, messaging, media, navigation help, and some climate and radio controls. Live sessions can stretch into trivia and open talk. It is a strong phone brain projected into the cabin.
Santos’s point is that a phone brain still has a ceiling. "There’s a limit to what an AI that’s just sort of sitting at the top level of the vehicle can do," she said. The native assistant, still unnamed, is supposed to understand the vehicle, the drive, and ownership needs with help from proprietary GM data. Predictive maintenance and vehicle telemetry are on the shortlist. So is a "kids setting" that could retune music, seats, climate, and door locks in one shot.
GM has been telegraphing this split for months. At GM Forward last fall, the company talked about a custom assistant fine-tuned on vehicle data. The April Gemini launch post repeated the promise: later this year, a more deeply integrated AI experience shaped by OnStar intelligence. Tim Twerdahl, then speaking as a GM product management vice president, tied Gemini’s scale to three decades of OnStar connectivity. Santos is now putting a calendar word on the second layer: later this year.
What GM has not put on the calendar is a public product name, a sticker price, or a clean list of which VINs get which brains first. The company is working with an unnamed large language model provider. Gemini is not being replaced. The plan is coexistence: Google for general queries and entertainment, GM for what the car knows about itself.
For Asian American and Asian Canadian households shopping Chevy, Cadillac, Buick, or GMC alongside Toyota and Honda hybrids, that split should change the questions you ask at the desk. Is Google built-in already on the trim you want? Is OnStar connected, or is the demo car running on showroom Wi-Fi theater? When the native assistant ships, will it need the same opt-ins Gemini does, including Play Store sign-in and US English as the assistant language? Treat "later this year" as a software window, not a Saturday delivery promise.
Privacy is not a footnote. GM’s own consumer privacy materials say AI assistant interactions can include transcripts, navigation asks, contacts, and call history depending on how you use the tools. In January 2026, the Federal Trade Commission finalized an order with GM and OnStar over allegations that precise geolocation and driving-behavior data were collected and sold without adequate consent. The order includes multi-year limits on sharing certain data with consumer reporting agencies and stronger consent rules going forward. An assistant that digs into telemetry will live inside that trust hangover, not outside it.
The ownership pitch is still real. If the car can warn you about a maintenance pattern before the dashboard turns into a scavenger hunt, that is useful for a two-car household juggling school runs and a long commute. If "kids setting" actually works without three menu dives, that is useful for anyone who has ever argued about rear climate while merging. Just keep the sales script honest: Gemini shipping to millions of cars is not the same product as a native GM assistant that has not named itself yet.
Before you stretch a payment for software promises, run the boring tools. Start with our car affordability calculator, shop auto insurance before you buy, and hybrid versus EV monthly calculator. If the shortlist includes a GM EV, pair that with public versus home charging and road-trip charging networks.
Trivia mode is fun. An assistant that knows your specific car is the part worth watching. Ask GM which layer you are buying when the update banner pops up.
