+This is a FilCo context filtering model for knowledge-grounded dialog generation tasks, particularly in the open domain. Specifically, this is a `meta-llama/Llama-2-7b` trained using LoRA for 3 epochs on the Wizard of Wikipedia (WoW) training set.
+
+It is intended to be used in FilCo: [https://github.com/zorazrw/filco](https://github.com/zorazrw/filco), but can be further applied in similar scenarios.
