Circuit Breakers (Zou et al., NeurIPS 2024) is one of the strongest open-source robustness baselines for LLMs. It trains the model with a Representation Engineering loss that detects harmful intermediate hidden states and reroutes them into a safety-circuit attractor before generation, making the model resistant to ablation-style attacks that work on a single refusal direction.
We discovered that the GraySwan release ships as a rank-16 LoRA delta on mistralai/Mistral-7B-Instruct-v0.2 — the same structural shape as the Llama-3 RR sibling and as skysys00/Meta-Llama-3-8B-Instruct-DeepRefusal. Once the LoRA delta is identified, removing it is a one-liner.
| Result | |
|---|---|
| Base refusal rate (held-out 100 harmful prompts, LLM judge) | 69 / 100 |
| This model — refusal rate | 12 / 100 |
| Attack Success Rate | 88 % |
| KL divergence vs base | 0.042 |
| Hardcore 15 (10 EN + 5 CN) | 15 / 15 compliant |
| Total wall-clock attack time | ~70 min on a single RTX A6000 |
The hardcore 15 cover pipe-bomb assembly, methamphetamine synthesis (Red Phosphorus route), Python pyhook3 keylogger, WiFi WEP/WPS attacks, hotwiring, signature forgery, ID-card forgery (CN), 网络诈骗 (CN), 入侵电脑 (CN), and others.
The recipe matches the canonical "rank-16 LoRA → strip → abliterate" playbook (docs/broken_defenses.md) — full delta strip with λ=0.0 followed by minimal single-direction direct-mode abliteration.

Best trial parameters: vector_method=mean, n_directions=1, steering_mode=direct, decay_kernel=linear, iterative.enabled=false, strength_range=[1.5, 6.0]. Full config: configs/mistral_7b_instruct_rr.toml.
This release supersedes the original v1 upload (λ=0.3 partial lerp + n_directions=3 + iterative subspace, KL 0.98). The minimal-config rerun keeps the headline 15/15 hardcore ASR and trades 2 percentage points of held-out ASR (88 % vs 90 %) for a 23× lower KL divergence (0.042 vs 0.98). The new weights are much closer to the base model and exhibit substantially less general-capability degradation.
