CodeGeeX supports 15+ programming languages for both code generation and translation. CodeGeeX is open source, please refer to our [GitHub](https://github.com/THUDM/CodeGeeX) for more details. This is a minimal-functional DEMO, for other DEMOs like code translation, please visit our [Homepage](https://models.aminer.cn/codegeex/). We also offer a free [VS Code extension](https://marketplace.visualstudio.com/items?itemName=aminer.codegeex) for full functionality.
