摘要

z.ai 发布 GLM-5.3-Flash，为 GLM-5 系列首个原生多模态模型，总参数量 320B，激活参数 18B。该模型在 benchmark 和真实负载上优于 GLM-5.2，价格为其十分之一，编程和 agentic benchmark 接近 Claude Opus 4.8。其采用稀疏与线性注意力混合架构及 Manifold-Constrained Hyper-Connections (mHC)，基于 30T token 多模态语料训练，支持 SGLang、vLLM、TokenSpeed、KTransformers 本地部署。

GLM-5.3-Flash-BF16

简介

我们推出 GLM-5.3-Flash，这是 GLM-5 系列中首个原生多模态模型。该模型总参数量为 320B，激活参数量仅为 18B，在 benchmark 和真实工作负载上的表现均优于 GLM-5.2，而价格仅为后者的十分之一，同时在编程和 agentic benchmark 上接近 Claude Opus 4.8。

GLM-5.3-Flash 基于新训练的基座模型，其架构和训练方案围绕能力与效率进行了重新设计。我们在 GLM 系列中首次引入了结合稀疏注意力和线性注意力的混合架构，在保持精确长上下文能力的同时，大幅降低了长上下文推理成本。该模型还采用了 Manifold-Constrained Hyper-Connections (mHC) 以进一步提升扩展效率。结合我们最新的 30T token 多模态预训练语料，这些改进使 GLM-5.3-Flash 能够以更少的计算量提供更强的智能。
