 ## Introduction
 
-The application of language models to code generation has sparked significant interest recently. You have probably heard of [Codex](https://arxiv.org/pdf/2107.03374v2.pdf), the model behind [Github Copilot](https://copilot.github.com/), or [AlphaCode](https://arxiv.org/pdf/2203.07814v1.pdf) for competition-level programming. These models aren't open-source and it is hard to reproduce them with a limited budget and incomplete information about their training. The ML community has luckily contributed some code models to allow for further research.

-It can be easy to get lost between the different models, so at Hugging Face, we aim to democratize ML and centralize all information in the 🤗 hub to make the usage of open-source tools easier and more efficient. Code Models aren't an exception, you can find all open-source code models on the hub, with several code datasets and evaluation metrics. In this blog, we will give an overview of these tools and how to use them.
