From the model card
NuminaMath is a series of language models that are trained with two stages of supervised fine-tuning to solve math problems using chain of thought (CoT) and tool-integrated reasoning (TIR):
NuminaMath 7B CoT is the model from Stage 1 and was fine-tuned on AI-MO/NuminaMath-CoT, a large-scale dataset of 860k+ math competition problem-solution pairs.
Here's how you can run the model using the pipeline() function from 🤗 Transformers:
import torch
from transformers import pipeline
pipe = pipeline("text-generation", model="AI-MO/NuminaMath-7B-TIR", torch_dtype=torch.bfloat16, device_map="auto")
messages = [
{"role": "user", "content": "For how many values of the constant $k$ will the polynomial $x^{2}+kx+36$ have two distinct integer roots?"},
]
prompt = pipe.tokenizer.apply_chat_template(messages, tokenize=False, add_generation_prompt=True)
gen_config = {
"max_new_tokens": 1024,
"do_sample": False,
"tokenizer": pipe.tokenizer,
}
outputs = pipe(prompt, **gen_config)
text = outputs[0]["generated_text"]
print(text)
NuminaMath 7B CoT was created to solve problems in the narrow domain of competition-level mathematics. As a result, the model should not be used for general chat applications. With greedy decoding, we find the model is capable of solving problems at the level of AMC 12, but often struggles generate a valid solution on harder problems at the AIME and Math Olympiad level. The model also struggles to solve geometry problems, likely due to it's limited capacity and lack of other modalities like vision.
The following hyperparameters were used during training:
