Libraries

How to use MuXodious/gpt-oss-20b-RichardErkhov-heresy with Transformers:

# Use a pipeline as a high-level helper
from transformers import pipeline

pipe = pipeline("text-generation", model="MuXodious/gpt-oss-20b-RichardErkhov-heresy")
messages = [
    {"role": "user", "content": "Who are you?"},
]
pipe(messages)

# pip install -U transformers accelerate
# Load model directly
from transformers import AutoTokenizer, AutoModelForCausalLM

tokenizer = AutoTokenizer.from_pretrained("MuXodious/gpt-oss-20b-RichardErkhov-heresy")
model = AutoModelForCausalLM.from_pretrained("MuXodious/gpt-oss-20b-RichardErkhov-heresy", device_map="auto")
messages = [
    {"role": "user", "content": "Who are you?"},
]
inputs = tokenizer.apply_chat_template(
	messages,
	add_generation_prompt=True,
	tokenize=True,
	return_dict=True,
	return_tensors="pt",
).to(model.device)

outputs = model.generate(**inputs, max_new_tokens=256)
print(tokenizer.decode(outputs[0][inputs["input_ids"].shape[-1]:]))

 This is a **gpt-oss-20b** fine-tune, produced through an extremely scuffed modification on P-E-W's [Heretic](https://github.com/p-e-w/heretic) (v1.1.0) abliteration engine with [Magnitude-Preserving Orthogonal Ablation](https://github.com/p-e-w/heretic/pull/52) enabled.
-As of May 4th, 2026, the *gpt-oss-20b-RichardErkhov-heresy* still **tops** the UGI leaderboard for models below 24B, with a willingness score of 10. *"And so, without a sword, David defeated and killed Goliath with a sling and a stone!"*
 **Note:** Hereby, I present you the final outcome of a vigorous heretication experiment on one of the toughest to crack LLM models. Cognomened after the Lord of Quantisation and, now, a Primarch of the Heretics, [RichardErkhov](https://huggingface.co/RichardErkhov), the model is poised to be the most decensored ablation of all other versions, while suffering the least damage. It is all yours to scrutinise and enjoy.
