Swift
Swift is a toolkit for the full-parameter and parameter-efficient fine-tuning of large language and multimodal models. It functions as a multimodal model trainer for text, image, video, and audio data, and includes specialized tools for model compression and reinforcement learning from human feedback.
The framework provides an alignment toolkit for optimizing model behavior using preference learning algorithms and reinforcement learning. It integrates parameter-efficient fine-tuning methods to adapt models with minimal memory and compute requirements, alongside utilities for reducing hardware overhead through weight quantization and compression.
The system covers a broad training surface including specialized workflows for embeddings, rerankers, and sequence classification. It incorporates distributed training acceleration via parallelism, memory optimization for long-text sequences, and integrated modules for measuring model performance and reliability.
The project includes tools for model deployment and serving using hardware acceleration backends.
