# zephyr-7b-sft-qlora

This model is a fine-tuned version of [mistralai/Mistral-7B-v0.1](https://huggingface.co/mistralai/Mistral-7B-v0.1) on the HuggingFaceH4ultrachat_200k dataset.
It is the first step (Step 1 SFT, see below) of building Zephyr, i.e. before DPO.
It achieves the following results on the evaluation set:
- Loss: 0.9523
