Partial The explorer UI is vibe-codeable, but its core is steering a 4B-parameter model across every MLP neuron and storing all rollouts, which needs GPU compute and interpretability research skill.
What it would actually take: A real version needs an inference harness for Qwen3.5-4B with activation hooks, a steering method that adds scaled neuron directions during generation, and batched GPU runs over tens of thousands of neurons. Storing and indexing every rollout also requires a results database and a viewer. The hard parts are the compute budget and the mechanistic interpretability know-how to make steering results meaningful.
