Hugging Face Transformers

What is Hugging Face Transformers?

Hugging Face Transformers is an open-source Python library that defines state-of-the-art machine learning models for text, vision, audio and multimodal tasks. It supports both inference and training.

Key capabilities of Hugging Face Transformers

• Pretrained models: Download models from the Hugging Face Hub.
• Pipelines: Task-level API with default models for common tasks.
• Fine-tuning: Adapt pretrained models to your data.
• Multiple modalities: Text, vision, audio and multimodal models.
• GPU batching: Pipelines use GPUs when available and batch inputs.
• Model-definition framework: A common definition shared across training and inference tools.

How Hugging Face Transformers works

You load a model and tokenizer by name from the Hub or call a pipeline for a task such as sentiment analysis or translation. Pipelines choose a default model and handle batching and GPU use. For custom work you fine-tune a model on your own data with the training APIs.

Who uses Hugging Face Transformers?

Transformers is used by ML engineers, data scientists and researchers building NLP, vision and speech features. It is the common starting point for applying open models.

Hugging Face Transformers pricing

Transformers is free and open source under the Apache License 2.0. Individual models on the Hub carry their own licenses, and some restrict commercial use, so check each model.

Hugging Face Transformers alternatives

Alternatives include spaCy, which offers production NLP pipelines, OpenAI API, which provides hosted models without self-hosting, and Cohere, which offers hosted language model APIs.
