模型介绍

XVERSE-MoE-A36B 是由深圳元象科技自主研发的支持多语言的大语言模型（Large Language Model），使用混合专家模型（MoE，Mixture-of-experts）架构，模型的总参数规模为 2554 亿，实际激活的参数量为 360 亿，本次开源的模型为底座模型 XVERSE-MoE-A36B，主要特点如下：

• 模型结构：XVERSE-MoE-A36B 为 Decoder-only 的 Transformer 架构，将密集模型的 FFN 层扩展为专家层，不同于传统 MoE 中每个专家的大小与标准 FFN 相同（如Mixtral 8x7B ），使用了更细粒度的专家，每个专家是标准 FFN 大小的 1/4，并设置了共享专家（Shared Expert）和非共享专家（Non-shared Expert）两类，共享专家在计算时始终被激活，非共享专家通过 Router 选择性激活。
• 训练数据：构建了海量高质量、多样化的数据对模型进行充分训练，包含中、英、俄、西等 40 多种语言，通过精细化设置不同类型数据的采样比例，使得中英两种语言表现优异，也能兼顾其他语言效果；模型使用 8K 长度的训练样本进行训练；在模型训练过程中进行了若干次数据的切换，来动态的引入持续处理的高质量数据，同时伴随数据采样比的调整。
• 训练策略：在切换数据的同时，为了使模型对新进数据进行快速且充分的学习，对学习率调度器也进行了相应调整。
• 训练框架：针对 MoE 模型中独有的专家路由和权重计算逻辑，进行了深入定制优化，开发出一套高效的融合算子，以提升计算效率。同时，为解决 MoE 模型显存占用和通信量大的挑战，设计了计算、通信和 CPU-Offload 的 Overlap 处理方式，从而提高整体吞吐量。

Model Introduction

XVERSE-MoE-A36B is a multilingual large language model, independently developed by Shenzhen Yuanxiang Technology which is using Mixture-of-experts (MoE) architecture. The total parameter scale of the model is 255 billion, with an actual number of activated parameters being 36 billion. The models released this time is the base model XVERSE-MoE-A36B. Its key features are as follows:

• Model Structure: XVERSE-MoE-A36B uses the mainstream Decoder-only Transformer network structure that extends the FFN layer of dense models to expert layers. Unlike traditional MoE model where each expert has the same size as standard FFN (such as Mixtral 8x7B), it uses more fine-grained experts, with each expert being 1/4 the size of a standard FFN. It includes shared experts and non-shared experts, where shared experts are always activated during computation, and non-shared experts are selectively activated through a Router.
• Training Data: The model has been thoroughly trained on a large-scale high-quality dataset, including more than 40 languages such as Chinese, English, Russian, and Spanish. The sampling ratio of different types of data is finely set, which makes the performance of Chinese and English excellent, and also takes into account the effect of other languages; The model is trained using training samples of length 8k; During the model training process, several data switches were made to dynamically introduce continuously processed high-quality data, along with adjustments to the data sampling ratio.
• Training Strategy: While switching data, corresponding adjustments were also made to the learning rate scheduler to ensure the model could quickly and thoroughly learn from the newly introduced data.
• Training Framework: We conducted in-depth customized optimization for the unique expert routing and weight calculation logic in the MoE model, developed an efficient fusion operator to improve computational efficiency. At the same time, to address the challenges of high memory consumption and communication volume in the MoE model, we designed a processing method for overlapping computation, communication, and CPU-Offload to increase overall throughput.

The models sizes, architectures and learning rate of XVERSE-MoE-A36B are showed as follows:
