Introduction

Moonlight-16B-A3B is a high-performance large language model optimized for the Hygon DCU platform. Built on a Mixture of Experts (MoE) architecture, the model features a total of 16 billion parameters with approximately 3 billion active parameters per inference, striking an optimal balance between high performance and efficient inference throughput. Deeply optimized for Hygon GPU hardware, Moonlight-16B-A3B supports the vLLM inference framework, making it well-suited for large-scale deployment scenarios.

Integrated Deployment

  • Out-of-the-box inference scripts with pre-configured hardware and software parameters
  • Released FlagOS-Hygon container image supporting deployment within minutes

Consistency Validation

  • Rigorously evaluated through benchmark testing: Performance and results from the FlagOS software stack are compared against native stacks on multiple public benchmarks.

Technical Overview

FlagOS is a fully open-source system software stack designed to unify the "model–system–chip" layers and foster an open, collaborative ecosystem. It enables a "develop once, run anywhere" workflow across diverse AI accelerators, unlocking hardware performance, eliminating fragmentation among vendor-specific software stacks, and substantially lowering the cost of porting and maintaining AI workloads.

With core technologies such as FlagScale, together with vllm-plugin-fl, distributed training/inference framework, FlagGems universal operator library, FlagCX communication library, and FlagTree unified compiler, the FlagRelease platform leverages the FlagOS stack to automatically produce and release various combinations of <chip + open-source model>.

This enables efficient and automated model migration across diverse chips, opening a new chapter for large model deployment and application.

FlagGems

FlagGems is a high-performance, generic operator library implemented in Triton language. It is built on a collection of backend-neutral kernels that aims to accelerate LLM training and inference across diverse hardware platforms.

FlagTree

FlagTree is an open-source unified compiler for multiple AI chips. It provides unified compilation capabilities across multiple backends and rapidly implements single-repository multi-backend support.

FlagScale and vllm-plugin-fl

FlagScale is a comprehensive toolkit designed to support the entire lifecycle of large models. It integrates capabilities from Megatron-LM and vLLM to provide an end-to-end solution for training and inference.

vllm-plugin-fl is a vLLM plugin built on the FlagOS unified multi-chip backend.

FlagCX

FlagCX is a scalable and adaptive cross-chip communication library for distributed AI workloads.

FlagEval Evaluation Framework

FlagEval is a comprehensive evaluation system and open platform for large models. It supports large-scale benchmark evaluation across NLP, CV, Audio, and Multimodal tasks.
