Show HN: Nanbeige 4.1-3B running in the browser via WebGPU

This is a 3B parameter model from Nanbeige with surprisingly strong benchmarks. It beats Qwen3-32B on Arena-Hard and LiveCodeBench despite being 10x smaller. (Also be warned it thinks a lot).

I wrapped it in a simple browser demo using Transformers.js + WebGPU. It downloads the q4 ONNX weights (~1.7GB) and runs fully client-side. no server required. Falls back to WASM if WebGPU isn't available.
