The post describes a proof of concept for dynamically suppressing refusal behavior in the open-weight Qwen3-4B model without changing its weights. It uses multi-layer steering via PyTorch forward hooks to inject signals into residual streams during inference, aiming to preserve the base model while altering responses to sensitive prompts.
