+# glm-4v-9b
+
+GLM-4-9B 是智谱 AI 推出的最新一代预训练模型 GLM-4 系列中的开源版本。
+在语义、数学、推理、代码和知识等多方面的数据集测评中，GLM-4-9B 及其人类偏好对齐的版本 GLM-4-9B-Chat 均表现出较高的性能。
+除了能进行多轮对话，GLM-4-9B-Chat 还具备网页浏览、代码执行、自定义工具调用（Function Call）和长文本推理（支持最大 128K 上下文）等高级功能。
+本代模型增加了多语言支持，支持包括日语，韩语，德语在内的 26 种语言。我们还推出了支持 1M 上下文长度（约 200 万中文字符）的模型。
+本仓库是 GLM-4-9B 的多模态开源版本 GLM-4V-9B 模型。
+
+## 运行模型
+
+```python
+import torch
+from PIL import Image
+from transformers import AutoModelForCausalLM, AutoTokenizer
+
+device = "cuda"
+
+tokenizer = AutoTokenizer.from_pretrained("THUDM/glm-4v-9b", trust_remote_code=True)
+
+query = '描述这张图片'
+image = Image.open("your image").convert('RGB')
+inputs = tokenizer.apply_chat_template([{"role": "user", "image": image, "content": "描述这张图片"}],
+                                       add_generation_prompt=True, tokenize=True, return_tensors="pt",
+                                       return_dict=True)  # chat mode
+
+inputs = inputs.to(device)
+model = AutoModelForCausalLM.from_pretrained(
+    "THUDM/glm-4v-9b",
+    torch_dtype=torch.bfloat16,
+    low_cpu_mem_usage=True,
+    trust_remote_code=True
+).to(device).eval()
+
+gen_kwargs = {"max_length": 2500, "do_sample": True, "top_k": 1}
+with torch.no_grad():
+    outputs = model.generate(**inputs, **gen_kwargs)
+    outputs = outputs[:, inputs['input_ids'].shape[1]:]
+    print(tokenizer.decode(outputs[0]))
+```
