Hugging Face
The de facto hub for open-source ML models, datasets, and Spaces demos — the GitHub of machine learning.
Definition
Hugging Face hosts open-weight models (Llama, Mistral, Qwen), datasets, and interactive Spaces. Its Transformers and Datasets libraries are the standard Python entry points for fine-tuning and inference. For automation work, Hugging Face is the canonical source when an LLM, embedding model, or speech model must run on-prem or in a private VPC.
