Dynamic Abliteration bypasses LLM guardrails via Engram steering
Dynamic Abliteration adapts DeepSeek's Engram conditional memory architecture to dynamically intercept intermediate residual streams in open-weight models via PyTorch forward hooks. By combining an N-gram hash core with dynamic context gating, it injects steering vectors to selectively suppress refusal behavior without altering base model weights.
Permanent weight surgery is an obsolete hammer; runtime activation steering proves that safety guardrails in open-weight models can be bypassed dynamically without collateral capability damage.
- –Non-destructive execution: By leaving weights frozen and gating residual stream interventions at runtime, models avoid the catastrophic drift and perplexity penalties typical of traditional weight abliteration.
- –Context-aware gating: Leveraging DeepSeek's Engram architecture with O(1) hash lookups enables rapid detection of refusal patterns and triggers steering only when necessary, bypassing the blunt, all-tokens degradation of static vectors.
- –Multi-layer defense bypass: Distributing steering across multiple middle layers prevents downstream layers from reconstructing the safety representations that single-layer interventions fail to suppress.
- –Structural implications for AI safety: This underscores that post-training safety alignment in open-weight weights is fundamentally fragile against lightweight inference-time hooks.
