How to use internlm/Intern-S2-Preview with Transformers:

# Use a pipeline as a high-level helper
from transformers import pipeline

pipe = pipeline("image-text-to-text", model="internlm/Intern-S2-Preview", trust_remote_code=True)
messages = [

        "content": [
            {"type": "image", "url": "https://huggingface.co/datasets/huggingface/documentation-images/resolve/main/p-blog/candy.JPG"},
            {"type": "text", "text": "What animal is on the candy?"}
        ]
    },
]
pipe(text=messages)

# Load model directly
from transformers import AutoModelForImageTextToText
model = AutoModelForImageTextToText.from_pretrained("internlm/Intern-S2-Preview", trust_remote_code=True, device_map="auto")

I think you guys should mention that this model is 35B MoE with 3B active parameters in README.md, this is a great advantage which is not mentioned for users who might assume that this is a 35B dense model

I didnt assume anything dude, it's for people who are less technical and your claim is top model use MoE is true but this is not a top model, models in this range usually include dense models like Qwen 3.7 27B and Gemma 4
