# TESS 2 v0.3 Base

This model is the diffusion adapted TESS 2. This model is a simplex-based diffusion model adapted from Mistral v0.3 7B, further trained on Dolma 1.7.
For more details, please check out our paper [TESS-2: A Large-Scale, Generalist Diffusion Language Model](https://arxiv.org/abs/2502.13917).
This is the model based on Mistral v0.3.

**This is the diffusion-adapted base model, which has not yet undergone instruction tuning. We recommend further tuning this model on your dataset of interest, or checking out the [instruction tuned version](https://huggingface.co/hamishivi/tess2).**

This model will only work with our custom codebase found [here](https://github.com/hamishivi/tess-2) -- please go there to see details on how to run training.
