Model Card
Perceptron Mk1.5 is Perceptron AI's embodied-reasoning model for physical agents, accepting text, image, video, and audio input and returning text alongside points, boxes, polygons, video clips, and object tracks, all from one model with no per-platform retraining.
It leads on three of four video object segmentation benchmarks (Molmo2-Track, Ref-DAVIS17, ReasonVOS) and localizes hands in first-person video 50% better than Gemini's strongest model. With tool calling and web search enabled, it improves 36.1 points on MMSearch, and it runs 2-5x faster end to end than Mk1.
At $0.15 per million input tokens and $1.50 per million output tokens, Mk1.5 suits developers building drone, quadruped, smart-glasses, or robotics pipelines that need spatial outputs and native audio understanding alongside text.
