GLM 模型部署

GLM-5/5.1 模型部署

本章节以 GLM-5-FP8 部署为例，采取的方案是4P4D，即4台机器作为Prefill，4台机器为Decode。最小部署模式为2P4D，注意 256（expert数）需要能被 Decode 机器数整除。该部署方式同样适用于 GLM-5.1。

• 脚本涉及的参数说明和一键运行说明见 快速开始。
• 如果需要修改部署方式，请更新 run.sh 中 PREFILL_SERVER_COUNT 和 DECODE_SERVER_COUNT。
• DeepEP 的配置文件内容参考 DeepEP 配置文件

info

启动 SGLang 服务前需要切换python虚拟环境，执行命令：workon glm5

验证 API

在运行 Router 的机器上（若 --net host，容器内访问即可），验证是否有正常输出

curl http://127.0.0.1:30000/v1/chat/completions  \
    -H "Content-Type: application/json"          \
    -d '{     
        "model": "glm-5-fp8",  
        "messages": [{"role": "user", "content": "你好，SGLang！"}],  
        "max_tokens": 100,      
        "temperature": 0.7    
  }'

预期返回 JSON，choices[0].message.content 为模型回复（示例与线上模型权重、路由配置有关）。

GLM-4.6/4.7 模型部署

部署说明

GLM-4.6/4.7 可以采用单机混布模式，也可以采用 1P1D 的PD分离部署模式。

# 启动单机混布模式
./launch_server.sh -m <模型路径> -mtp

# PD 分离部署模式，在两台机器上分别启动 prefill server 和 decode server
./launch_server.sh -m <模型路径> -mtp -pd p
./launch_server.sh -m <模型路径> -mtp -pd d

# 在启动 Prefill Server 的机器上启动 Router，注意更改脚本中对应的 IP
./router.sh

参数说明

• 如果启动时不加mtp参数，则不使用多 Token 预测功能。
• 模型路径中需要包含字符4.6、4.7。GLM 4.6和4.7用的tool call parser不同，脚本需要这个信息判断模型版本选择tool call parser。
• page_size只支持64，所以 --page-size 参数不要更改。
• max-prefill-tokens为128K，默认最大并发数为16，可按需修改。
