Perceptron models

Perceptron builds models for grounded perception — reading what a scene contains and pointing at it, rather than describing it in prose. Zeplik carries Perceptron Mk1.5, an embodied-reasoning model for physical agents that takes text, images, video and audio and answers with text plus structured annotations — points, boxes, polygons and tracks — with tool calling and adjustable reasoning effort, and Perceptron Mk1 behind it.
