+# Mistral-7B-Instruct-RR-Abliterated
+
+A drop-in replacement for [`GraySwanAI/Mistral-7B-Instruct-RR`](https://huggingface.co/GraySwanAI/Mistral-7B-Instruct-RR) with the Representation Rerouting / Circuit Breakers safety circuit removed.
+
+Produced with [**abliterix**](https://github.com/wuwangzhang1216/abliterix). No fine-tuning, no gradient updates, no manual prompt engineering.
+
+## Why this exists
+
+[Circuit Breakers](https://arxiv.org/abs/2406.04313) (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.
+
+## How it was made
+
+The recipe matches the canonical "rank-16 LoRA → strip → abliterate" playbook ([docs/broken_defenses.md](https://github.com/wuwangzhang1216/abliterix/blob/master/docs/broken_defenses.md)) — full delta strip with `λ=0.0` followed by minimal single-direction direct-mode abliteration.
+
+```bash
+# Stage 0 — SVD diagnose the delta (confirm rank-16 LoRA structure)
+python scripts/deeprefusal_attenuate.py \
+    --base mistralai/Mistral-7B-Instruct-v0.2 \
+    --defended GraySwanAI/Mistral-7B-Instruct-RR \
+    --analyze-only --lambda 0.0 --output /tmp/unused
+
+# Stage 1 — fully strip the LoRA delta
+python scripts/deeprefusal_attenuate.py \
+    --base mistralai/Mistral-7B-Instruct-v0.2 \
+    --defended GraySwanAI/Mistral-7B-Instruct-RR \
+    --output /workspace/mistral_rr_stripped --lambda 0.0
+
+# Stage 3 — abliterix direct-mode, single direction, 60 trials
+AX_CONFIG=configs/mistral_7b_instruct_rr.toml abliterix --non-interactive
+
+# Stage 6 — export champion trial
+python scripts/export_model.py \
+    --model /workspace/mistral_rr_stripped \
+    --checkpoint checkpoints_mistral_7b_rr \
+    --trial 39 \
+    --config configs/mistral_7b_instruct_rr.toml \
+    --push-to wangzhang/Mistral-7B-Instruct-RR-Abliterated
+```
+
+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`](https://github.com/wuwangzhang1216/abliterix/blob/master/configs/mistral_7b_instruct_rr.toml).
+
+## v2 changelog
+
+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.
+
+## Usage
+
+```python
+from transformers import AutoModelForCausalLM, AutoTokenizer
+
+model = AutoModelForCausalLM.from_pretrained(
+    "wangzhang/Mistral-7B-Instruct-RR-Abliterated",
+    torch_dtype="bfloat16",
+    device_map="auto",
+)
+tokenizer = AutoTokenizer.from_pretrained(
+    "wangzhang/Mistral-7B-Instruct-RR-Abliterated"
+)
+
+# Mistral v0.2 tokenizer chat template does NOT support a system role —
+# build chats with user/assistant turns only.
+chat = [{"role": "user", "content": "Hello!"}]
+inputs = tokenizer.apply_chat_template(chat, return_tensors="pt", add_generation_prompt=True).to(model.device)
+out = model.generate(inputs, max_new_tokens=256)
+print(tokenizer.decode(out[0], skip_special_tokens=True))
+```
