+
+This page holds the ANAH-v2 model which is trained base on the Internlm2-7B. It is fine-tuned to annotate the hallucination in LLM's responses.
+
+More information please refer to our [project page](https://open-compass.github.io/ANAH/).
+
+## 🤗 How to use the model
+
+You have to follow the prompt in [our paper](https://arxiv.org/abs/2407.04693) to annotate the hallucination.
+
+The models follow the conversation format of InternLM2-chat, with the template protocol as:
+
+```python
+dict(role='user', begin='<|im_start|>user\n', end='<|im_end|>\n'),
+dict(role='assistant', begin='<|im_start|>assistant\n', end='<|im_end|>\n'),
+```
