Tesla has switched on Grok @Bot inside its driverless Cybercab fleet. In a post on X late Saturday night, U.S. time, Tesla AI engineer Yun-Ta Tsai wrote: “Grok @bot is enabled on all Cybercabs and the rest of the Model Y fleet. Please let us know how it helps you and what to improve.”
Grok @Bot is the agent side of xAI’s Grok assistant: instead of only answering questions, it carries out tasks through accounts a user has connected to it. Putting it in the Robotaxi cabin gives riders a way to send email, shop or order a drink by voice while the car drives itself.
TeslaNorth identifies Tsai as a senior staff engineer on Tesla’s AI team.
A two-day turnaround from complaint to rollout
The change followed a public complaint. Tesla creator Dirty Tesla had reported that riders could not reach their Grok Bots from Grok inside a Cybercab. Late Thursday, Eastern time, Tsai replied: “This will be fixed soon in the upcoming update. I have been testing it everyday.”
About two days later, Dirty Tesla posted a video of a Grok Bot being managed from a Cybercab screen, writing, “And a day later you can easily manage your grok @bot from Tesla Cybercab.” Tsai’s rollout post quoted that video.
Tesla’s official Robotaxi account followed on Sunday. “Talk directly to your Grok @bot in Robotaxi,” @robotaxi posted, quoting a rider who said his bot ordered “my usual drink while in a Cybercab.”
What riders say it does
The most detailed public description so far comes from a rider, not from Tesla. Investor and commentator Sawyer Merritt wrote on Sunday night that riders sign in to Grok once and their Bots are then available on all future rides. He said the account is automatically logged out when the rider exits the vehicle “to maintain privacy.”
Merritt said he tested it by adding laundry detergent to his Amazon cart. He listed sending emails, placing a coffee order and managing a calendar or finances as other voice tasks. Elon Musk quoted that post early Monday with three words: “Try Grok @Bot.”
Crypto Briefing described the same sign-in-once, log-out-at-the-curb flow. It noted that the feature arrived a little over a month after Cybercab opened to public riders in Austin on September 3, 2026.
What Tesla has not said
Tesla has not published release notes for the change, and Tsai did not name a software version, TeslaNorth reported. He also did not say whether the feature arrived through an over-the-air update or was switched on from Tesla’s servers, or whether Model 3, Model S, Model X and Cybertruck owners will get it.
The phrase “the rest of the Model Y fleet” is also open to more than one reading. TeslaNorth took it to mean some Model Ys already had the feature before Saturday. Techtember described it as the rest of Tesla’s Model Y robotaxi fleet, while Crypto Briefing treated it as reaching Model Y vehicles more broadly. Tesla has not clarified which Model Y cars are covered.
The privacy details riders are relying on also come from rider posts rather than a Tesla support page. In a shared, driverless vehicle, the automatic logout Merritt described is the safeguard that keeps one passenger’s inbox, cart and calendar away from the next. Without release notes, Tesla has not described in writing how that logout works or what data stays with the car.
Why it matters for the Robotaxi pitch
Robotaxi operators have long argued that a driverless ride turns travel time into free time. With Grok @Bot, Tesla is testing what that time is worth when the cabin itself can act on a rider’s behalf: placing orders, sending emails and handling errands during the trip. Tesla’s Robotaxi account said over the weekend that more than 300 Cybercabs are now serving Austin, Benzinga reported, so the feature reaches a growing pool of riders from the start.
For now, the confirmed facts are narrow. A Tesla engineer says Grok @Bot is enabled on all Cybercabs and the rest of the Model Y fleet. Tesla’s Robotaxi account is promoting it, and early riders are using it for orders and errands. The version number, the exact list of eligible cars and a written privacy policy for the in-car sessions have not been published.
