OpenMath2-Llama3.1-70B

OpenMath2-Llama3.1-70B is obtained by finetuning Llama3.1-70B-Base with OpenMathInstruct-2.

The model outperforms Llama3.1-70B-Instruct on MATH by 3.9%.

Model	GSM8K	MATH	AMC 2023	AIME 2024	Omni-MATH

How to use the models?

Our models are trained with the same "chat format" as Llama3.1-instruct models (same system/user/assistant tokens). Please note that these models have NOT been instruction-tuned on general data and thus might not provide good answers outside of the math domain.

We recommend using instructions in our repo to run inference with these models, but here is an example of how to do it through transformers api:

import transformers
import torch

model_id = "nvidia/OpenMath2-Llama3.1-70B"

pipeline = transformers.pipeline(
    "text-generation",
    model=model_id,
    model_kwargs={"torch_dtype": torch.bfloat16},
    device_map="auto",
)

messages = [
    {
        "role": "user", 
        "content": "Solve the following math problem. Make sure to put the answer (and only answer) inside \\boxed{}.\n\n" + 
        "What is the minimum value of $a^2+6a-7$?"},
]

outputs = pipeline(
    messages,
    max_new_tokens=4096,
)
print(outputs[0]["generated_text"][-1]['content'])
