  # Introduction
  `sat`(`SwissArmyTransformer`) is a flexible and powerful library to develop your own Transformer variants.
  `sat` is named after "swiss army knife", meaning that all the models (e.g. BERT, GPT, T5, GLM, CogView, ViT...) **share the same backbone code** and cater for versatile usages with some extra light-weight mixins.

  # SwissArmyTransformer: A Unified Backbone for Custom Transformer Architectures
  `sat` (`SwissArmyTransformer`) is a flexible and powerful library designed to simplify the development and training of your own Transformer variants. Unlike general-purpose frameworks, `sat` provides a **unified backbone code** that all models (e.g., BERT, GPT, T5, GLM, CogView, ViT) share, enabling rapid experimentation and efficient large-scale pretraining and finetuning (100M~20B parameters) with light-weight mixins.

  ## Why SwissArmyTransformer?
  While frameworks like Hugging Face Transformers provide a vast collection of pre-built models, SwissArmyTransformer focuses on providing a unified, extensible backbone for *developing your own* custom Transformer variants. We integrate advanced parallelism techniques (like DeepSpeed-ZeRO and Megatron-LM style model parallelism) to efficiently pretrain and finetune large models (100M~20B parameters) from scratch, offering a flexible alternative for researchers and developers building novel architectures.
