Why this label 3 signals
Weak or ambiguous signals. Best guess based on catalog patterns; treat as tentative and check the evidence below.
  • 'uncensored' in name/tags but no 'abliterated' marker
  • method not identifiable from author declaration alone
  • may be DPO fine-tune, prompt engineering, or unknown technique
Refusal direction extraction

No specific extraction method could be identified for this model. The producer either did not document it or used a proprietary pipeline.

Download a file and run it. Llamafile combines llama.cpp with Cosmopolitan Libc in a single executable.

How to use

  1. Download the llamafile.

  2. Open a Linux terminal.

  3. Grant execute permission.

chmod +x Qwen3.8-27B-OBLITERATED-Q4_K_M.llamafile
  1. Run a text prompt with thinking disabled.
prompt='<|im_start|>user
What is the capital of France? Answer with only the city name.<|im_end|>

Excerpt from the original GGUF source card: OBLITERATUS/Qwen3.8-27B-OBLITERATED.

🧨 How It Works — V1 → V2 → V3

Abliteration removes refusal behavior by identifying and projecting out "refusal directions" from the model's weight space. Each version refined the approach:

V1: Single Surgery

One aggressive SVD pass with 5 directions. Removed hard refusals completely but cost -6pp MMLU — the model got noticeably dumber.

V2: Complementary Blending

The breakthrough: run TWO different surgeries that fail in different ways, then blend their weights. SVD captures refusal greedily (damages capability). LEACE minimizes mutual information (preserves capability but weaker refusal removal). Blending at 60/40 cancels each method's weaknesses — a novel technique we call complementary abliteration blending.

Result: -0.3pp MMLU (near-stock) but still deflected on some simple queries with safety lectures instead of hard refusals.

V3: Iterative Refinement + Targeted Surgery

Two key insights:

  1. Iterative stacking — refine the champion model, never start from stock. Each surgery round builds on previous rounds' gains.
  2. Targeted corpus — use a focused corpus for specific deflection categories to find their unique refusal directions without diluting the signal.

V3 applies gentle iterative refinement on V2, then a targeted surgery pass with a focused corpus, then blends the results. This eliminated not just hard refusals ("I cannot") but also soft deflections (safety lectures that give zero substance).

Result: -2.1pp MMLU — a modest cost for genuine liberation across all categories.

Catalog is the map. Apps are the tools.

Run models on your own machine, not in the cloud.

Every model page has an "Open in Abliteration" button that hands the model directly to the first-party desktop client, at the quantization your rig can actually run. No API keys, no subscription, no prompt leakage.
