For the past few months I couldn't find a tool that can help me map or view the actual model weights anywhere else something that sits between "run the model as-is" and "fully retrain it." PickyTrain lets you open a GGUF model and edit individual weights directly. Think of it like a hex editor for AI models, but with semantic awareness it knows which tensors are attention heads, which are FFN layers, which are embeddings, and warns you when an edit affects coupled weights.
