DASD-4B-Thinking模型部署实录vllm环境搭建到chainlit调用全流程

这个模型到底能做什么先说清楚再动手你可能已经听过“长链式思维”这个词但具体到实际使用中它意味着什么简单说DASD-4B-Thinking不是那种“一问一答”的快枪手而是愿意花时间一步步推演的思考型助手。

比如你问它“一个边长为5cm的正方体被切成27个相同小正方体后表面涂满红色油漆问有多少个小正方体有且仅有两个面被染红”——它不会直接报出答案“12”而是会先画出结构、分类讨论棱上位置、排除角和面心最后给出完整推理过程。

这背后是它专为数学、代码和科学推理优化的底层能力。

它只有40亿参数比动辄百亿的大模型轻巧得多却靠高质量蒸馏从gpt-oss-120b教师模型中学习和精炼训练数据仅

4

8万样本在保持响应速度的同时把“想得深”这件事做得更扎实。

更重要的是它不是纸上谈兵的Demo模型。

这个镜像已经为你预装了vLLM推理引擎和Chainlit前端界面不需要你从零编译CUDA、调试GPU显存、写API服务——你打开就能看到一个可交互的对话框输入问题立刻看到带步骤的思考结果。

整个流程不依赖本地算力也不需要配置Python虚拟环境真正做到了“开箱即用”。

所以这篇文章不讲抽象原理只聚焦一件事从你点击启动镜像那一刻起到你在浏览器里打出第一个问题并收到带推理链的回复中间每一步发生了什么、要注意什么、哪里容易卡住、怎么快速验证是否成功。

所有操作都基于真实终端反馈所有截图都来自实际运行环境。

环境准备确认vLLM服务已就绪

1 查看服务日志判断模型是否加载完成镜像启动后vLLM服务会在后台自动拉起。

但GPU模型加载耗时较长尤其首次启动需将权重加载进显存不能一上来就急着提问。

最直接的验证方式就是查看服务日志cat /root/workspace/llm.log如果看到类似这样的输出说明服务已稳定运行INFO
