Mistral Common

What is it?

mistral-common is a set of tools to help you work with Mistral models.

Our first release contains tokenization. Our tokenizers go beyond the usual text <-> tokens, adding parsing of tools and structured conversation. We also release the validation and normalization code that is used in our API.

We are releasing three versions of our tokenizer powering different sets of models.

• v1: open-mistral-7b, open-mixtral-8x7b, mistral-embed
• v2: mistral-small-latest, mistral-large-latest
• v3: open-mixtral-8x22b

Installation

pip

You can install mistral-common via pip:

pip install mistral-common

From Source

Alternatively, you can install from source directly. This repo uses poetry as a dependency and virtual environment manager.

You can install poetry with

pip install poetry

poetry will set up a virtual environment and install dependencies with the following command:

poetry install
