# TruthX: Alleviating Hallucinations by Editing Large Language Models in Truthful Space
> [Shaolei Zhang](https://zhangshaolei1998.github.io/), [Tian Yu](https://tianyu0313.github.io/), [Yang Feng](https://people.ucas.edu.cn/~yangfeng?language=en)*
TruthX models for paper "[TruthX: Alleviating Hallucinations by Editing Large Language Models in Truthful Space](https://arxiv.org/pdf/2402.17811.pdf)".
**TruthX** is an inference-time method to elicit the truthfulness of LLMs by editing their internal representations in truthful space, thereby mitigating the hallucinations of LLMs. On the [TruthfulQA benchmark](https://paperswithcode.com/sota/question-answering-on-truthfulqa), TruthX yields an average **enhancement of 20% in truthfulness** across 13 advanced LLMs.

This repo provides TruthX models trained on a variety of LLMs:
- Llama-1-7B, Alpaca-7B
- Llama-2-7B, Llama-2-7B-Chat, Vicuna-7B-v1.5
- Mistral-7B-v0.1, Mistral-7B-Instruct-v0.1, Mistral-7B-Instruct-v0.2
- Baichuan2-7B-Base, Baichuan2-7B-Chat
- Chatglm3-6B-Base, Chatglm3-6B
