+### Transformers
 
 ```python
-from transformers import AutoProcessor, Qwen3_5_VLForConditionalGeneration
+from transformers import AutoProcessor, AutoModelForImageTextToText
 
 # Requires transformers>=5.3.0
-model = Qwen3_5_VLForConditionalGeneration.from_pretrained(
-    "OpenMed/Qwen3.5-2B-MedVL", torch_dtype="auto", device_map="auto"
+model_id = "OpenMed/Qwen3.5-2B-MedVL"

+    }
+]
+
+inputs = processor.apply_chat_template(messages, add_generation_prompt=True, tokenize=True, return_dict=True, return_tensors="pt").to(model.device)
+output = model.generate(**inputs, max_new_tokens=512)
+print(processor.decode(output[0][inputs["input_ids"].shape[-1]:], skip_special_tokens=True))
+```
+

+]}]
+
+output = llm.chat(messages, SamplingParams(temperature=0, max_tokens=512))
+print(output[0].outputs[0].text)
+```
+
+### SGLang
