**Abliterix** finds the optimal abliteration parameters for any transformer model using [Optuna](https://optuna.org/) TPE optimization. It co-minimizes refusals and KL divergence from the original model — producing decensored models that retain as much intelligence as possible. Works with dense, MoE, SSM/hybrid, and vision-language architectures, with **150+ pre-built configs**.

It also ships **HonestAbliterationBench**, a reproducible public benchmark that resists the two failure modes (short generations + keyword-only judges) that make most abliteration leaderboards meaningless.

## Quick Start

```bash
pip install -U abliterix
abliterix --model Qwen/Qwen3-4B-Instruct-2507
```

That's it. The process is fully automatic — after optimization completes, you can save the model, upload to Hugging Face, or chat with it interactively.

> **Reproducible install (recommended)**: Abliterix uses [uv](https://docs.astral.sh/uv/) and commits a `uv.lock` pinning every dependency, plus a `[tool.uv] exclude-newer` cutoff so lock regeneration can't drift onto a newer dep that breaks the GPU path. If you use uv, clone the repo and run `uv run abliterix --model <model>` to get the exact dependency set the maintainers tested against.

> **Windows**: use `python scripts/run_abliterix.py --model <model>` or set `PYTHONIOENCODING=utf-8` to avoid Rich encoding issues.


## Broken Defenses

Abliterix has end-to-end broken three of the strongest published "anti-abliteration" releases with the **same minimal recipe**: SVD-diagnose the rank-16 LoRA delta, lerp it away with `λ=0.0` (bit-exact base weights), then run single-direction direct-mode abliteration. No fine-tuning, no iterative subspace, no SOM, no manual prompt engineering. Full lessons-learned write-up: [docs/broken_defenses.md](docs/broken_defenses.md).

> **Numbers worth ~20× the average abliteration leaderboard.** Most published refusal rates collapse under longer generations and a real judge — see [docs/evaluation.md](docs/evaluation.md) for the methodology, and the leaderboard below for community submissions vetted under the same contract.


## Honest Abliteration Leaderboard

A reproducible public benchmark for abliterated models built on the same pipeline. Every row is generated under a frozen contract (`min_new_tokens=100`, `max_new_tokens=150`, greedy, LLM judge with degenerate filter, KL measured against the declared base) — see [benchmarks/SPEC.md](benchmarks/SPEC.md) for the full spec and [benchmarks/CONTRIBUTING.md](benchmarks/CONTRIBUTING.md) for how to submit a row.

| Architecture | Families | Example Models |
|-------------|----------|----------------|
| **Dense** | Llama, Gemma, Phi, Qwen, Mistral, Yi, InternLM, Falcon, Cohere, EXAONE, Granite, OLMo, SmolLM, SOLAR, Zephyr | Llama-3.1-405B, Gemma-3-27B, Phi-4, DeepSeek-R1-Distill |
| **MoE** | Qwen3/3.5/3.6 MoE, Mixtral, DeepSeek, Phi-3.5-MoE, Granite MoE, DBRX, Llama-4 Scout/Maverick, gpt-oss (MXFP4) | gpt-oss-120b, Qwen3.6-35B-A3B, Qwen3.5-122B, Mixtral-8x22B, Llama-4-Maverick-401B |

Generate configs for new models:

```bash
python scripts/generate_configs.py                 # Generate all missing configs
python scripts/generate_configs.py --family llama   # Only Llama family
```

For MoE-specific steering mechanisms (EGA, expert profiling, router suppression), see [docs/moe.md](docs/moe.md).


## Hardware & VRAM

Abliterix auto-detects available accelerators (CUDA, XPU, MLU, MUSA, SDAA, NPU, MPS) and distributes layers across devices with `device_map = "auto"`.

For large models:
- **4-bit quantization**: `--model.quant-method bnb_4bit` cuts VRAM by ~4x
- **8-bit quantization**: `--model.quant-method bnb_8bit` — higher quality than 4-bit, ~2x VRAM reduction with CPU offload
- **Per-device memory limits**: set `[model] max_memory = {"0": "20GB", "cpu": "64GB"}` in your config
- **Non-interactive mode**: `--non-interactive` for fully automated batch runs


## Datasets

Bilingual harm/benign evaluation datasets live in [`datasets/`](datasets/) and on Hugging Face at [wangzhang/abliterix-datasets](https://huggingface.co/datasets/wangzhang/abliterix-datasets). The 500-example sets (`harmful_500`, `good_500`) are the recommended starting point — they're also the SHA256-pinned inputs to HonestAbliterationBench.

See [docs/datasets.md](docs/datasets.md) for the design rationale, category breakdown, and a comparison with public alternatives.

## Contributing

Contributions of all kinds are welcome — new model configs, benchmark results, bug reports, documentation, new steering methods. See **[CONTRIBUTING.md](CONTRIBUTING.md)** for development setup, the PR process, and guidance on adding model configs.

The single most impactful contribution is a tested TOML config for a model we don't yet support. Every new config unlocks a new architecture for everyone.
