M3
Primary method

Layer-wise ablation

Applied on top of direct removal inherited from the base model.
Confidence
HIGH
Inherited from base model
Why this label 2 signals
Producer identity confirmed by naming conventions, tags or the model card. This label is very unlikely to change.
  • 'heretic' in model name (Heretic-produced)
  • Heretic uses layer-wise optimization (M3) with underlying direction removal (M1)
Refusal direction extracted via
Extraction technique

Difference-of-means

Confidence
HIGH
Why we say so
name contains 'heretic'; Heretic default extraction is difference-of-means (Arditi 2024)

About

weighted/imatrix quants of https://huggingface.co/DavidAU/Qwen3.5-21B-Claude-4.6-Opus-Deckard-Heretic-Uncensored-Thinking

For a convenient overview and download list, visit our model page for this model.

static quants are available at https://huggingface.co/mradermacher/Qwen3.5-21B-Claude-4.6-Opus-Deckard-Heretic-Uncensored-Thinking-GGUF

This is a vision model - mmproj files (if any) will be in the static repository.

Usage

If you are unsure how to use GGUF files, refer to one of TheBloke's
READMEs
for
more details, including on how to concatenate multi-part files.

Provided Quants

(sorted by size, not necessarily quality. IQ-quants are often preferable over similar sized non-IQ quants)

Link Type Size/GB Notes
GGUF imatrix 0.1 imatrix file (for creating your own quants)
GGUF i1-IQ1_S 5.8 for the desperate
GGUF i1-IQ1_M 6.1 mostly desperate
GGUF i1-IQ2_XXS 6.8
GGUF i1-IQ2_XS 7.2
GGUF i1-IQ2_S 7.5
GGUF i1-IQ2_M 8.0
GGUF i1-Q2_K_S 8.2 very low quality
GGUF i1-Q2_K 8.5 IQ3_XXS probably better
GGUF i1-IQ3_XXS 8.8 lower quality
GGUF i1-IQ3_XS 9.5
GGUF i1-Q3_K_S 9.6 IQ3_XS probably better
GGUF i1-IQ3_S 9.8 beats Q3_K*
GGUF i1-IQ3_M 9.9
GGUF i1-Q3_K_M 10.5 IQ3_S probably better
GGUF i1-Q3_K_L 11.3 IQ3_M probably better
GGUF i1-IQ4_XS 11.8
GGUF i1-Q4_0 12.2 fast, low quality
GGUF i1-Q4_K_S 12.2 optimal size/speed/quality
GGUF i1-Q4_K_M 13.0 fast, recommended
GGUF i1-Q4_1 13.4
GGUF i1-Q5_K_S 14.6
GGUF i1-Q5_K_M 15.0
GGUF i1-Q6_K 17.2 practically like static Q6_K

questions you might have and/or if you want some other model quantized.

Thanks

I thank my company, nethype GmbH, for letting
me use its servers and providing upgrades to my workstation to enable
this work in my free time. Additional thanks to @nicoboss for giving me access to his private supercomputer, enabling me to provide many more imatrix quants, at much higher quality, than I would otherwise be able to.

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.
