About

Open-source large-model training framework. Colossal-AI is an open-source distributed training framework focused on efficient large-model training across multiple parallelism strategies — tensor parallel, pipeline parallel, ZeRO data parallel, and sequence parallel. The project's positioning is as a more accessible alternative to NVIDIA Megatron-LM for organizations that need similar capabilities without committing to NVIDIA's broader ecosystem.
