AI inference outside the data center · Cars, robots, phones · Flagship: Tesla fleet, Cybercab and Optimus

Most AI chips by unit count sit in cars, robots and phones, not data centers. Tesla closes the loop in Texas: fleet video trains models on Cortex in Austin, and the models run on AI5 chips made in Taylor and Arizona; China ships the most units, led by Horizon Robotics' 15 million chips.

The Tesla loop: fleet video trains models on Cortex 1 and Cortex 2 in Austin, and the models run on AI4 and AI5 chips in cars, Cybercab and Optimus, with AI5 made in Taylor, Texas and Arizona; and units carrying AI driving or robot compute by platform, on a log scale THE TESLA LOOP: TRAIN IN AUSTIN, INFER IN THE CAR FLEETCars, Cybercab, Optimus CORTEX 1 + 2Giga Texas, 205+ MW AI4 / AI5 CHIPSTaylor TX, Arizona video in, trained models back out UNITS WITH AI DRIVING OR ROBOT COMPUTE (LOG SCALE) 1K 10K 100K 1M 10M Horizon Journey chipsChina, cumulative Tesla vehicles builtUS, cumulative BYD God's EyeChina Tesla FSD subscriptionsActive Huawei Qiankun ADSChina Unitree humanoidsChina, built Waymo vehiclesUS fleet

Inference at the edge

AI That Runs in the Car, the Robot or the Phone

Inference on vehicles and devices runs a trained model on a chip inside the product, not in a data center. The data center still matters: it trains the models and, for features like Grok in Teslas or Apple Intelligence, serves the requests the device cannot handle.

  • Cars: driver assistance and robotaxis, from Tesla FSD and Waymo to China's Horizon Robotics, BYD and Huawei.
  • Robots: humanoids and warehouse robots on Nvidia Jetson Thor, Tesla AI chips or Chinese silicon.
  • Phones and PCs: neural processing units such as Qualcomm's Snapdragon X2 Elite at 80 TOPS, with Apple sending heavier requests to its own Private Cloud Compute servers, built in Houston.

Flagship

Tesla: One Loop From Fleet to Cortex and Back

  • Fleet: 10 million vehicles built and 1.74 million active FSD subscriptions as of Q3 2026, up 67% from a year earlier.
  • Robotaxi: live in seven metros, from Austin, Dallas and Houston to Florida, with driverless Cybercab rides in Austin since September 2026; Giga Texas can build more than 125,000 Cybercabs a year.
  • Optimus: production started on the Fremont lines in Q3 2026.
  • Training: fleet video trains models on Cortex 1 (over 90 MW) and Cortex 2 (over 115 MW) at Giga Texas; Tesla plans 400 MW of training compute by the end of 2026. See Tesla Cortex.
  • Chips made in the US: AI5 is made at Samsung in Taylor, Texas and TSMC in Arizona; AI6 goes to Samsung Taylor under a $16.5 billion contract.

Musk has proposed using idle cars as a 100 GW distributed inference fleet. By DatacentersX's estimate, today's roughly 8 to 9 million active Teslas hold a few exa-operations of INT8 compute, but draw only 1 to 2 MW while driving, and sit idle most of the day.

China

China Ships the Most Units

  • Horizon Robotics: 15 million Journey chips shipped across more than 40 brands, including Volkswagen China through the CARIZON joint venture.
  • BYD: God's Eye driver assistance on more than 2.3 million vehicles.
  • Huawei: Qiankun ADS on more than 1 million vehicles, using its own Ascend chips.
  • Robots: Chinese makers shipped more than 97% of the 19,100 humanoids sold worldwide in the first half of 2026; Unitree alone has built about 18,000.
