A unified, open-source system software stack designed for a variety of AI chips

FlagOS Overview

FlagGems

A high-performance general-purpose operator library implemented with the Triton programming language and its extended languages.

FlagTree

An open-source, unified compiler for multiple AI chips.

FlagScale

A comprehensive toolkit designed to support the entire lifecycle of large models.

FlagCX

A scalable and adaptive unified communication library for cross-chip environments.

Megatron-LM-FL

A fork of Megatron-LM that introduces a plugin-based architecture for supporting diverse AI chips, built on top of FlagOS, a unified open-source AI system software stack.

vllm-plugin-FL

A plugin for the vLLM inference/serving framework, built on FlagOS's unified multi-chip backend — including the unified operator library FlagGems and the unified communication library FlagCX.

TransformerEngine-FL
