+# 🙋🏻‍♂️欢迎来到🌟Tonic 的🦄Qwen-VL-Chat🤩Bot！🚀
+# 🙋🏻‍♂️Welcome to🌟Tonic's🦄Qwen-VL-Chat🤩Bot!🚀
+该WebUI基于Qwen-VL-Chat，实现聊天机器人功能。 但我必须解决它的很多问题，也许我也能获得一些荣誉。Qwen-VL-Chat 是一种多模式输入模型。 您可以使用此空间来测试当前模型 [qwen/Qwen-VL-Chat](https://huggingface.co/qwen/Qwen-VL-Chat) 您也可以使用 🧑🏻‍🚀qwen/Qwen-VL -通过克隆这个空间来聊天🚀。 🧬🔬🔍 只需点击这里：[重复空间](https://huggingface.co/spaces/Tonic1/VLChat?duplicate=true)
+加入我们：🌟TeamTonic🌟总是在制作很酷的演示！ 在 👻Discord 上加入我们活跃的构建者🛠️社区：[Discord](https://discord.gg/nXx5wbX9) 在 🤗Huggingface 上：[TeamTonic](https://huggingface.co/TeamTonic) 和 [MultiTransformer](https:/ /huggingface.co/MultiTransformer) 在 🌐Github 上：[Polytonic](https://github.com/tonic-ai) 并为 🌟 [PolyGPT](https://github.com/tonic-ai/polygpt-alpha) 做出贡献 ）
+This WebUI is based on Qwen-VL-Chat, implementing chatbot functionalities. Qwen-VL-Chat is a multimodal input model. You can use this Space to test out the current model [qwen/Qwen-VL-Chat](https://huggingface.co/qwen/Qwen-VL-Chat) You can also use 🧑🏻‍🚀qwen/Qwen-VL-Chat🚀 by cloning this space. 🧬🔬🔍 Simply click here: [Duplicate Space](https://huggingface.co/spaces/Tonic1/VLChat?duplicate=true)
