jan.ai: An Open-Source, Self-Hosted ChatGPT Alternative 122

Jan.ai, the desktop client is a ChatGPT alternative that runs on your own computer and comes with a local API server.

Jan comes with a local-first, AI-native, and cross-platform extension framework. In essence, Jan is a cross-platform, local-first, and AI-native framework that can be used to build anything. Developers can extend and customize everything from features to UI to branding. In fact, most of Jan's current features are actually built on top of this framework as extensions.

Jan stores data in the local file system. Your data never leaves your computer. You are free to delete, export, and migrate your data, and even migrate to other platforms.

Jan.ai Features:

• Compatible with open-source models (GGUF via llama.cpp, TensorRT via TensorRT-LLM, and remote APIs)

• Compatible with most operating systems: Windows, Mac, Linux, with GPU acceleration via llama.cpp

• Stores data in open file formats

• Local API server mode

• Customizable via extensions
