Proposal to Add Mistral Model Family

Overview

I'd love to see the Mistral model family added to the list of supported models. These models show interesting performance improvements over LLaMA2 models.

Details

More information about these models can be found in this announcement by Mistral.

Model Checkpoints

The models and checkpoints are available on Hugging Face, as detailed in the Mistral HF documentation.

Here are the direct links to the model checkpoints:

• Mistral-7B-v0.1: Raw Checkpoint
• Mistral-7B-Instruct-v0.1: Raw Checkpoint

Hi @fpaupier,
We also will take this up, but right now you can use GenericModel for them.
