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.

You can install mistral-common via pip:
pip install mistral-common
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
