Hugging Face
The central hub for the open-source AI ecosystem — effectively the GitHub of AI. On Hugging Face, you can find and download thousands of pre-trained models, datasets, and demos. It's where most open-source fine-tuned models are published and where the research community shares work. If you're building with open-source AI or evaluating alternatives to proprietary APIs, Hugging Face is where you start looking.
In practice
You want to run an open-source language model on your own servers rather than using an API. Hugging Face is where you find and download those models — it's the GitHub of AI models. Developers use it to experiment with alternatives to Claude, fine-tune models on custom data, or deploy AI without sending data to a third-party API.
