Hugging Face
The hub for open-source machine learning models, datasets, and spaces — essential for working with transformers and LLMs in Python
Visit Hugging Face →Hugging Face hosts hundreds of thousands of pre-trained models, datasets, and interactive demo “Spaces” — the default place to find and download an open-source model before training anything from scratch. Its transformers Python library provides a common interface for loading and running most of them, which is what makes it the practical starting point rather than just a model directory.
Relevant whether you’re fine-tuning a model or just calling one — see LangChain or DSPy for building applications on top of models sourced here.
