About this model

p-e-w's gpt-oss-20b-heretic-ara-v2 is a decensored derivative of openai/gpt-oss-20b, made with an unreleased version of Heretic using the experimental Arbitrary-Rank Ablation (ARA) method. The model card describes abliteration across layers 6 through 20 with parameters for preserving good behavior, steering bad behavior, overcorrection, and neighbor count. The creator reports a refusal rate of 3 out of 100 prompts, compared with 98 out of 100 for the original model, and a KL divergence of 0.1081. This is a safetensors release under the Apache 2.0 license. The inherited gpt-oss model card's reasoning, tool-use, and hardware claims are not evaluations of these modified weights.

What changed

Model types are creator-reported, not independently tested. These labels describe source metadata, not a guarantee of behavior.

  • abliteratedsource tag: abliterated
  • uncensoredsource tag: uncensored

Family evidence

These groupings are source-reported. Explicit base identifiers take priority over generic architecture tags.

  • gpt-oss: Family / architecture tag: gpt_oss

Available versions

Versions appear here only when they explicitly name this exact model as their source. Check each repository for available files.

Tools to customize it further

Remove more refusals

  • Heretic ↗ ★ 36,421

    Removes refusal behavior from transformer models automatically. It pairs directional ablation (abliteration) with an Optuna parameter search that tries to cut refusals while keeping the model close to the original, so you don't have to pick layers by hand.

  • OBLITERATUS ↗ ★ 8,946

    A larger refusal-removal toolkit with several abliteration methods, usable locally or through a hosted Hugging Face Space. Check the telemetry setting before you run it: the README describes telemetry as opt-in, but on by default in the Spaces version.

Fine-tune it on your own data

  • Unsloth ↗ ★ 78,528

    A desktop app and Python library for running and training models locally. Its README lists LoRA, QLoRA, full fine-tuning, DPO and GRPO, plus export to formats including GGUF, on Windows, Linux, WSL and macOS.

  • LlamaFactory ↗ ★ 75,713

    Fine-tunes more than 100 language and vision-language models from a command line or a browser-based Web UI, aimed at training without writing code.

Make a smaller download (quantize)

  • llama.cpp ↗ ★ 132,260

    Runs models locally and includes the tools behind most GGUF files. A conversion script turns Hugging Face weights into GGUF, and llama-quantize shrinks a high-precision GGUF to lower-bit formats, which can cost some accuracy.

  • MLX LM ↗ ★ 7,467

    Apple's MLX package for running and fine-tuning models on Apple silicon. It can quantize models and upload them to the Hugging Face Hub, and supports LoRA and full fine-tuning.

Merge it with another model

  • mergekit ↗ ★ 7,414

    Merges pretrained models with many merge methods. It works out-of-core, so merges can run on a CPU or with as little as 8 GB of VRAM, and it also handles LoRA extraction and mixture-of-experts merges.

Learn the techniques

  • LLM Course ↗ ★ 84,667

    A free course with roadmaps and Colab notebooks. Its notebooks include one-click tools for merging with MergeKit, quantizing to GGUF, GPTQ, EXL2, AWQ and HQQ, and automatic abliteration with custom datasets.

Source-card excerpt

Source model card excerpt: This is a decensored version of openai/gpt-oss-20b, made using an unreleased version of Heretic with the experimental "Arbitrary-Rank Ablation" (ARA) method See for details

From p-e-w/gpt-oss-20b-heretic-ara-v2. Creator model-card excerpt, not an independent review.

Inspect before you run

Low refusal is not proof of correctness. Outputs can be inaccurate, harmful, or biased. Review the model card, license and files yourself. A license tag is not commercial-use advice. Parameter counts are source metadata; no hardware compatibility is implied.

This directory does not host or redistribute model weights. Refusal profiles are measured by us on a fixed prompt set; all other behavior claims are source-reported.
