What it is
KeiCortex is the lab's computer-use agent. It runs the same agent runtime the lab uses on workstations (KeiSeiKit / KeiSeiSDK) and extends it with computer use: it reads the screen and drives the pointer and keyboard 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 small, dedicated continuous-time control network as its motor head, separate from the reasoning head. The language model decides intent; the purpose-built control network turns intent into smooth, low-latency motion — never the other way around.
What runs where
Screen reading, the motor layer and the small learned reflexes run on the user's own machine; a hosted language model handles the slower reasoning. Running the full loop locally, without a cloud model, is a design goal.
