Dev turns LLM structured output into a browser game running Gemma 4 locally via WebGPU
nicodotdev · x · 2026-10-21
Developer nicodotdev launched Token Arcade, a web app that gamifies LLM structured output. The model proposes candidate next tokens, you pick one, and the constraints decide whether it's valid—most likely ≠ valid, and even a capital letter can cost you points.
Technically, @googlegemma 4 runs fully in-browser via Transformers.js + WebGPU, with E2B for execution. Playable online now.
