Hugging Face's API provides programmatic access to 45,000+ models spanning text, vision, audio, and multimodal tasks. Core open-source libraries available via pip include:
- Transformers – model loading, fine-tuning, and inference
- Diffusers – diffusion model pipelines
- PEFT – parameter-efficient fine-tuning methods
- TRL – reinforcement learning from human feedback (RLHF) training
- Accelerate – distributed and mixed-precision training
- Tokenizers – fast, Rust-backed tokenization
- Safetensors – secure, fast tensor serialization
- Text Generation Inference – optimized LLM serving
- Transformers.js – in-browser ML inference
- smolagents – lightweight agent framework
All libraries integrate with PyTorch. Inference Endpoints offer REST-based deployment with GPU compute from $0.60/hour. Enterprise tiers add SSO, audit logs, and role-based access controls. The platform is open-source with 166,982 GitHub stars.
