Hugging Face Transformers - AI SDKs and Libraries Tool

Overview

Hugging Face Transformers is an open-source library that provides a unified API for thousands of pretrained models across text, vision, audio, video and multimodal tasks. It exposes high-level pipelines for common inference tasks (generation, classification, question answering, summarization, feature extraction) and lower-level primitives (AutoModel, AutoTokenizer) to load and customize models from the Hugging Face Model Hub. According to the GitHub repository, Transformers aims to make state-of-the-art transformer architectures accessible for both research and production use. The library supports multiple deep learning frameworks (PyTorch, TensorFlow and Flax/JAX), offers Trainer and utilities for fine-tuning, and integrates with related tooling: the Tokenizers library for fast tokenization, the Hugging Face Hub for model sharing, and Accelerate/bitsandbytes for optimized inference and mixed-precision or quantized execution. Transformers also provides export and deployment options (ONNX, TorchScript) and first-class support for parameter-efficient fine-tuning (PEFT/LoRA) workflows. Together these features let teams prototype quickly with pipelines and scale to production-grade inference and model sharing (see the GitHub repository and the Hugging Face Model Hub for detailed docs and examples).

Example Usage

Example (python):

from transformers import pipeline, AutoTokenizer, AutoModelForCausalLM

# Quick inference with a pipeline
generator = pipeline("text-generation", model="gpt2")
print(generator("In the future, AI will", max_new_tokens=40, do_sample=True, temperature=0.8))

# Manual load for more control
tokenizer = AutoTokenizer.from_pretrained("gpt2")
model = AutoModelForCausalLM.from_pretrained("gpt2")
inputs = tokenizer("Transformers make it easy to", return_tensors="pt")
outputs = model.generate(**inputs, max_new_tokens=50)
print(tokenizer.decode(outputs[0], skip_special_tokens=True))
