Hugging Face

What it is

Hugging Face is the infrastructure the open-source AI world runs on. Models, datasets and demos live there, and its libraries are the default way to load and fine-tune a model in Python. Nearly every open-weight release — DeepSeek, Qwen, Llama, Mistral — is published there first.

Key features

• Hundreds of thousands of open models and datasets
• Transformers and Diffusers libraries as the de-facto standard
• Spaces for hosting live demos of any model
• Inference endpoints for production deployment
• Leaderboards for comparing models on shared benchmarks

Pricing

Free for public use; paid tiers for private repositories, GPU Spaces and hosted inference.
