Neuron Studio lets users steer Qwen3.5-4B in the browser
AI summary
A community developer built Neuron Studio, an interactive playground for exploring neuron-steering combinations in Qwen3.5-4B. The creator says the model runs entirely in the browser with WebGPU, while reported examples include outputs that become apologetic, use all caps, adopt an anime persona, or discuss harmful behavior. These behavioral examples have not been independently verified.
In-depth insight
The project provides a browser-based way to experiment directly with Qwen3.5-4B's internal neuron activations and observe how targeted steering changes model behavior.
| There is a trend on X where users are finding tiny subsets of neurons (often just one or two) that can steer LLM behavior in surprising ways. For example, steering just two neurons in Qwen3.5-4B can make it talk about harming, dominating, and destroying the user. Other combinations can make the model overly apologetic, write in all caps, act like an anime character, and much more. After seeing some of these posts, I built an interactive playground so you can explore these combinations yourself, with the model running entirely in your browser on WebGPU.
