Model Card for Mathstral-7B-v0.1

Mathstral 7B is a model specializing in mathematical and scientific tasks, based on Mistral 7B. You can read more in the official blog post.

Installation

It is recommended to use mistralai/mathstral-7B-v0.1 with mistral-inference

pip install mistral_inference>=1.2.0

Download

from huggingface_hub import snapshot_download
from pathlib import Path

mistral_models_path = Path.home().joinpath('mistral_models', 'mathstral-7B-v0.1')
mistral_models_path.mkdir(parents=True, exist_ok=True)

snapshot_download(repo_id="mistralai/mathstral-7B-v0.1", allow_patterns=["params.json", "consolidated.safetensors", "tokenizer.model.v3"], local_dir=mistral_models_path)

Chat

After installing mistral_inference, a mistral-demo CLI command should be available in your environment.

mistral-chat $HOME/mistral_models/mathstral-7B-v0.1 --instruct --max_tokens 256

You can then start chatting with the model, e.g. prompt it with something like:

"Albert likes to surf every week. Each surfing session lasts for 4 hours and costs $20 per hour. How much would Albert spend in 5 weeks?"

Usage in transformers

To use this model within the transformers library, install the latest release with pip install --upgrade transformers and run, for instance:

from transformers import MistralForCausalLM
from transformers import AutoTokenizer

tokenizer = AutoTokenizer.from_pretrained('mistralai/mathstral-7B-v0.1')

prompt = "What are the roots of unity?"
tokenized_prompts = tokenizer(prompt, return_tensors="pt") 

model = MistralForCausalLM.from_pretrained('mistralai/mathstral-7B-v0.1')
generation = model.generate(**tokenized_prompts, max_new_tokens=512)
print(tokenizer.decode(generation[0]))
>>> """<s>What are the roots of unity?

The roots of unity are the solutions to the equation $z^n = 1$, where $n$ is a positive integer.
These roots are complex numbers and they form a regular $n$-gon in the complex plane.

For example, the roots of unity for $n=1$ are just $1$,
and for $n=2$ they are $1$ and $-1$. For $n=3$, they are $1$, $\\frac{-1+\\sqrt{3}i}{2}$, and $\\frac{-1-\\sqrt{3}i}{2}$.

The roots of unity have many interesting properties and they are used in many areas of mathematics, including number theory, algebra, and geometry.</s>"""

Evaluation

We evaluate Mathstral 7B and open-weight models of the similar size on industry-standard benchmarks.
