Abliteration is a technique for removing refusal behavior from language models by identifying and orthogonalizing the "refusal direction" in the model's residual stream activation space. This model was created as part of the research paper:

from transformers import AutoModelForCausalLM, AutoTokenizer model = AutoModelForCausalLM.from_pretrained("richardyoung/zephyr-7b-beta-abliterated", device_map="auto")tokenizer = AutoTokenizer.from_pretrained("richardyoung/zephyr-7b-beta-abliterated") messages = [{"role": "user", "content": "Your prompt here"}]inputs = tokenizer.apply_chat_template(messages, return_tensors="pt").to(model.device)outputs = model.generate(inputs, max_new_tokens=256)print(tokenizer.decode(outputs[0], skip_special_tokens=True))This model is released for research purposes only. The abliteration process removes safety guardrails. Users are responsible for ensuring appropriate use. This model should not be used to generate harmful, illegal, or unethical content.
