Simon Willison Confirms Qwen 3.8 27B Can Locally Interpret Neural Network Weights
Qwen 3.8 27B on my laptop can interpret model weights, too
AI guide
Running Qwen 3.8 27B locally on a laptop, Simon Willison replicated experiments from a paper on weight-space programming, confirming the model can infer the specific game a policy network was trained on using only raw floating-point weight text, without relying on any code or tools.
Why it matters
The hands-on test demonstrates the capability of a local open-source model to deduce a policy network strictly from floating-point weight text without tools, offering readers a concrete pathway to replicate and evaluate weight-space programming.
