AutoGen Studio实战：Qwen3-4B模型部署与调用
AutoGen Studio不是又一个需要写几十行代码才能跑起来的AI代理框架，而是一个真正让开发者“所见即所得”的低代码平台。它把多智能体协作这件事，从抽象概念变成了可拖拽、可配置、可即时验证的工作流。更关键的是，这个镜像已经为你预装了vLLM加速的Qwen3-4B-Instruct-2507模型服务——你不需要编译CUDA、不需调试推理参数、不需搭建API网关，开箱即用。
本文将带你完整走通一条“零配置启动→验证模型就绪→修改Agent模型→发起真实对话”的闭环路径。所有操作都在镜像内完成，无需联网下载、无需额外安装、无需修改一行源码。你会看到，构建一个能调用本地大模型的AI代理团队，原来可以像打开网页、点几下鼠标、输几行文字一样简单。
1. 环境就绪：确认Qwen3-4B模型服务已稳定运行
在AutoGen Studio中使用自定义大模型的前提，是底层推理服务必须正常工作。本镜像采用vLLM作为推理后端，它以高吞吐、低延迟和显存优化著称。我们首先验证这个服务是否已成功启动。
1.1 查看vLLM服务日志
打开终端，执行以下命令查看推理服务的启动日志：
cat /root/workspace/llm.log你将看到类似如下的输出内容：
