Colossal-AI

Colossal-AI is an open-source deep learning system designed for large-scale AI model training. It allows users to train and evaluate massive AI models efficiently across multiple GPUs or nodes, providing a flexible and modular framework for experimenting with distributed training strategies. Colossal-AI leverages the PyTorch framework and advanced parallelism techniques to deliver scalable and memory-efficient training, with a focus on usability, modularity, and open-source accessibility.

Features of Colossal-AI:

• Supports a wide range of training strategies, including data, model, and pipeline parallelism, using a unified interface.
• Optimized for large-scale deep learning pipelines, including memory-efficient computation, optimizer sharding, and gradient accumulation.
• Provides both Python API and CLI options for launching experiments and distributed training programs.
• Optionally supports multi-node and multi-GPU setups for training massive AI models efficiently.
• Open-source and actively maintained, widely used in AI research, model development, and educational projects.
• Cross-platform support for Linux, Windows, and macOS (depending on PyTorch and CUDA installation).
