# **ReasonEval-34B Model Card**

## Model Description

`ReasonEval-34B` is a 34B parameter decoder-only language model fine-tuned from [`llemma_34b`](https://huggingface.co./EleutherAI/llemma_34b). Given a mathematical problem and the solution, `ReasonEval-34B` assesses the problem-solving process in a step-by-step format from the following perspectives:
- **Validity**: The step contains no mistakes in calculation and logic.
- **Redundancy**: The step lacks utility in solving the problem but is still valid.


With ReasonEval, you can

- 📏 quantify the quality of reasoning steps free of human or close-source models.

- 🤖 find the potential invalid or redundant steps in the solutions even with the correct results.

- 🛠️ select high-quality training data for downstream tasks (e.g., fine-tuning).    

## Model Details

* **Model type**: `ReasonEval-34B`'s architecture is identical to [`llemma_34b`](https://huggingface.co./EleutherAI/llemma_34b), except that the
classification head for next-token prediction is replaced with a classification head for outputting the
possibilities of each class of reasong steps.
* **Language(s)**: English
