# **Mistral-ORPO-Capybara-7k (7B)**
|
||
|
||
**Mistral-ORPO** is a fine-tuned version of [mistralai/Mistral-7B-v0.1](https://huggingface.co/mistralai/Mistral-7B-v0.1) using the *[odds ratio preference optimization (ORPO)](https://arxiv.org/abs/2403.07691)*. With ORPO, the model directly learns the preference without the supervised fine-tuning warmup phase.
|
||
|
||
**Mistral-ORPO-ORPO-Capybara-7k** is fine-tuned for **2.5 hours on four A100s** exclusively on the **7k** instances of the distilled Capybara paired multi-turn conversation dataset, [argilla/distilabel-capybara-dpo-7k-binarized](https://huggingface.co/datasets/argilla/distilabel-capybara-dpo-7k-binarized), by [Argilla](https://huggingface.co/argilla).
