QEfficient is a Python library designed for optimizing transformer models and deploying them efficiently on Qualcomm Cloud AI 100 hardware. This library provides a seamless path from pre-trained HuggingFace models to production-ready inference on specialized AI accelerators. The library abstracts the complexity of model transformation, ONNX export, hardware compilation, and inference execution while maintaining compatibility with the familiar HuggingFace transformers interface. It supports text generation models, embedding models, vision-language models, and speech-to-text models with advanced features like continuous batching, speculative decoding, and parameter-efficient fine-tuning. For specific model architecture support, see Model Types and Architectures. For installation and environment setup, see Installation and Setup.

For detailed API documentation, see Core Architecture. QEfficient follows a layered architecture that transforms standard transformer models through multiple stages to achieve optimal performance on Qualcomm AI 100 hardware: Sources: QEfficient/transformers/models/modeling_auto.py61-102 QEfficient/base/modeling_qeff.py39-80 README.md61-83 [04/2025] Support for SpD, multiprojection heads.

Efficient Transformers are designed to mitigate the computational and memory requirements of standard transformer architectures, particularly when dealing with large-scale datasets or resource-constrained environments. They aim to address issues such as scalability and efficiency in training and inference. One approach used in efficient transformers is replacing the standard self-attention mechanism with more lightweight attention mechanisms, which reduce the computational complexity of attending to long sequences by approximating the attention mechanism with lower-rank... These approaches enable transformers to be more practical for real-world applications where computational resources are limited. There was an error while loading. Please reload this page.
