What it is
KeiCortex is the hardware home for the lab's agent stack — the part that turns a cluster of perception, reasoning, and control modules into a single autonomous system. It runs the same agent runtime the lab uses on workstations (KeiSeiKit / KeiSeiSDK), sized for embedded power and thermal envelopes, and it extends that runtime with computer-use-style orchestration — driving a screen, a tool, or a physical actuator through the same agent loop.
Reasoning is not the motor
A large reasoning model is not a motor controller, and the lab does not pretend otherwise: KeiCortex keeps a dedicated, small motor-control head (the lab's CubeDrive-family continuous-time controllers, the same family used on the wearable and vehicle hardware) separate from the reasoning head. The LLM decides intent; a purpose-built control network turns intent into smooth, low-latency motion — never the other way around.
Why local
An autonomous system that breaks when the network breaks is not autonomous. KeiCortex is designed to run the full agent loop offline, with optional cloud sync rather than required cloud dependency.
