AI Analysis
●●●BangerWizardryRabbit Hole
Runs PPO training entirely in-browser via TinyJit WebGPU kernels.
Strengths
- •TinyJit compilation pipeline enables complex ML training client-side.
- •Real-time visualization of policy, value, and entropy metrics.
- •Zero server dependency for the actual reinforcement learning loop.
Weaknesses
- •Strictly requires WebGPU adapter, excluding many older devices.
- •Niche educational demo rather than a production tool.

Play Bang Bang against a neural network
You play a minimalist web game while a neural net trains in real time, so the opponent starts weak and adapts to your playstyle. The landing page is extremely spare — the demo is quick to load and oddly charming, but there’s little signposting about the model, implementation details, or source code. Fun as a curiosity or teaching toy, but not novel enough to wow ML folks who’ve seen in-browser learning demos before.
