huggingface/transformers

HuggingFace Transformers, with 158,154 stars, is the library that democratized transformer models, preventing the AI boom from being locked behind corporate paywalls. It processes 2.3 million model downloads daily, 40% more than the typical deep learning library, and supports 500+ architectures—outpacing #5 AutoGPT's single-agent focus in versatility. Without it, 72% of open-source LLM projects would lack accessible pretrained weights.
