VisionPsy-Nano: state-of-the-art vision AI in its weight class, small enough to run on your phone

Tether AI Research is releasing VisionPsy-Nano, a family of ~460M-parameter vision-language models built to run on the device in your pocket. It leads its weight class on 16 of 17 benchmarks, beats models up to 2.3x its size on ScienceQA, instruction following and hallucination robustness, and the Flash variant reaches the first token in 0.3s on an iPhone 15. Open weights, Apache 2.0.
