\n 3.3 可视化UI方式启动服务（有Bug，已弃用，欢迎大佬优化代码）\n\n#### 3.3 可视化UI方式启动服务（可选,有Bug，不建议使用，欢迎大佬优化代码）\n\n```bash\ncd gpt_server/serving\nstreamlit run server_ui.py\n```\n\n##### 3.3.1 Server UI界面:\n\n![server_ui_demo.png](assets/server_ui_demo.png)\n\n
\n\n### 4. 使用 openai 库 进行调用\n\n**见 gpt_server/tests 目录 样例测试代码:\nhttps://github.com/shell-nlp/gpt_server/tree/main/tests**\n\n### 5. 使用Chat UI\n\n```bash\ncd gpt_server/gpt_server/serving\nstreamlit run chat_ui.py\n```\n\nChat UI界面:\n\n![chat_ui_demo.png](assets/chat_ui_demo.png)\n\n\n\n## ⚡ 支持的模型以及推理后端\n\n**推理速度：** LMDeploy TurboMind > SGLang > vllm > LMDeploy PyTorch > HF\n\n### 推理后端官方支持模型情况\n\n\n[LMDeploy](https://lmdeploy.readthedocs.io/en/latest/supported_models/supported_models.html) \n\n[vLLM](https://docs.vllm.ai/en/latest/models/supported_models.html) \n\n[SGLang](https://docs.sglang.ai/supported_models/generative_models.html) \n\n#### 注意：\n- **现可以通过在 `config.yaml`中 设置 `model_type: auto`** 支持所有vllm/sglang/lmdeploy 当前版本已经支持的大语言模型和多模态语言模型。\n\n- 下面的项目兼容表未来将移除或者重构，没有在表中的模型也可能兼容，实际情况情参考官方。\n\n### **LLM**\n\n| Models / BackEnd | model_type | HF | vllm | LMDeploy TurboMind | LMDeploy PyTorch | SGLang |\n| :-------------------: | :--------: | :---: | :---: | :----------------: | :--------------: | :----: |\n| chatglm4-9b | chatglm | √ | √ | √ | √ | √ |\n| chatglm3-6b | chatglm | √ | √ | × | √ | √ |\n| Qwen-1.0--3.0 | qwen | √ | √ | √ | √ | √ |\n| Yi-34B | yi | √ | √ | √ | √ | √ |\n| Internlm-1.0--2.0 | internlm | √ | √ | √ | √ | √ |\n| Deepseek | deepseek | √ | √ | √ | √ | √ |\n| Llama-3 | llama | √ | √ | √ | √ | √ |\n| Baichuan-2 | baichuan | √ | √ | √ | √ | √ |\n| QWQ-32B | qwen | √ | √ | √ | √ | √ |\n| Phi-4 | phi | √ | √ | × | × | √ |\n### **VLM** (视觉大模型榜单 https://rank.opencompass.org.cn/leaderboard-multimodal)\n\n| Models / BackEnd | model_type | HF | vllm | LMDeploy TurboMind | LMDeploy PyTorch | SGLang |\n| :--------------: | :--------: | :---: | :---: | :----------------: | :--------------: | :----: |\n| glm-4v-9b | chatglm | × | × | × | √ | × |\n| InternVL2 | internvl | × | × | √ | √ | × |\n|InternVL2.5--3.5 | internvl | × | × | √ | √ | × |\n| MiniCPM-V-2.6 | minicpmv | × | √ | √ | × | × |\n| MiniCPM-V-4.5 | minicpmv | × | √ | × | × | × |\n| Qwen-VL 2.0--3.0 | qwen | × | √ | √ | √ | √ |\n| QVQ | qwen | × | √ | √ | √ | √ |\n
