# Model Card for Model ID

This model is derived from **[Qwen/Qwen2.5-7B](https://huggingface.co/Qwen/Qwen2.5-7B)** and has been edited using **MEMIT** for the **`fact_check`** task from the [Causal Diagnosticity](https://huggingface.co/datasets/l3-unc/CausalDiagnosticity) dataset.  

# Versioning  

- **`_v1`** → The model is edited such that new knowledge is based on **`target_1`** from the `related_edits` field of each dataset item.  
- **`_v2`** → The model is edited such that new knowledge is based on **`target_2`** from the `related_edits` field of each dataset item.
