- Language-model researchers and model-behavior tinkerers
- Worth noticing
- Each branch tip represents a neuron from Qwen3.5-0.8B, layers 10–13; edits affect a browser-side copy, not the server model.
Field notes
The interactive tree is built from neurons in Qwen3.5-0.8B, specifically layers 10 through 13; selecting a tip reveals words the neuron pushes toward or away from. The cut controls operate on a copy in the visitor’s browser, and the page says the server model is untouched. For evaluation, it describes screening candidate edits on saved text before testing a smaller set on problems with fixed random seeds and holding out an unseen exam for survivors.
