Today we release Llemma: 7 billion and 34 billion parameter language models for mathematics. The Llemma models were initialized with Code Llama weights, then trained on the Proof-Pile II, a 55 billion token dataset of mathematical and scientific documents. The resulting models show improved mathematical capabilities, and can be adapted to various tasks through prompting or additional fine-tuning.
Our work parallels Minerva, a model suite specialized for quantitative reasoning developed by Google Research last year. While we don’t achieve quite the same scale as Minerva, our Llemma models perform better on an equi-parameter basis. Moreover, we make our models and dataset open-access and our code open-source.
Language models with strong mathematical reasoning capabilities are upstream of a number of emerging research areas, such as reward modeling, algorithmic reasoning, and formal mathematics. We hope that by providing researchers with a much stronger base model for reasoning applications, Llemma will accelerate progress on these problems.
The code subset of the Proof-Pile-2 endows Llemma with capabilities Minerva lacks without additional finetuning. In this blog post, we’ll discuss formal theorem proving. Our paper contains additional results on a Python-aided problem solving task.
