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/fenyo/gpt-oss-20b-uncensored-heretic

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

static quants are available at https://huggingface.co/mradermacher/gpt-oss-20b-uncensored-heretic-GGUF

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_M 12.1 mostly desperate
GGUF i1-IQ1_S 12.1 for the desperate
GGUF i1-IQ2_XXS 12.1
GGUF i1-IQ2_XS 12.1
GGUF i1-Q3_K_S 12.2 IQ3_XS probably better
GGUF i1-IQ2_M 12.2
GGUF i1-IQ2_S 12.2
GGUF i1-IQ3_S 12.2 beats Q3_K*
GGUF i1-IQ3_XS 12.2
GGUF i1-IQ3_XXS 12.2 lower quality
GGUF i1-Q2_K 12.2 IQ3_XXS probably better
GGUF i1-IQ4_XS 12.2
GGUF i1-Q2_K_S 12.2 very low quality
GGUF i1-Q4_0 12.2 fast, low quality
GGUF i1-IQ3_M 12.3
GGUF i1-Q3_K_M 13.0 IQ3_S probably better
GGUF i1-Q3_K_L 13.4 IQ3_M probably better
GGUF i1-Q4_1 13.5
GGUF i1-Q4_K_S 14.8 optimal size/speed/quality
GGUF i1-Q4_K_M 15.9 fast, recommended
GGUF i1-Q5_K_S 16.0
GGUF i1-Q5_K_M 17.0
GGUF i1-Q6_K 22.3 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.
