Today we're releasing Sequoia 1 Preview, the first model in our Sequoia family. It gives any product with a camera accurate eye tracking, without dedicated hardware, and it gets more accurate the longer each person uses it.
Learns each person
Faces, cameras and seats all differ. Instead of one model for everyone, Sequoia fits a model to each person on their own device, then keeps sharpening it with every action they confirm: a click, a tap, a press of a button. After twenty of them, gaze error falls by 27%.
- Seated, first use
- 1.65°
- Seated, after 20 uses
- 1.20°
- Moving, after 20 uses

How it compares
On first use, Sequoia 1 Preview is level with Tobii Nexus, Tobii's webcam eye tracker. After twenty uses it is 27% more accurate, and its precision is within 0.04° of Tobii's dedicated infrared tracker.

Built for the car first
Since July 2026, every new car, van, truck and bus sold in the EU must warn a driver who looks away from the road, so every new vehicle now carries a camera on its driver. A car has a few drivers for years, and they show where they are looking all the time: every touch of the screen, every press of a wheel button. That is the setting Sequoia was designed for.
The same holds in cockpits and simulators, on accessibility devices, in research and on industrial controls.
Small enough to share the machine
Sequoia needs no GPU and no dedicated hardware. We optimized it with Kestrel, our engine for running neural networks on the chips products already have. Camera frames, faces and each person's model stay on the device.
