messages = [
    {
        "role": "user",
        "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)

# pip install -U transformers accelerate
# Load model directly
from transformers import AutoProcessor, AutoModelForMultimodalLM

processor = AutoProcessor.from_pretrained("tiny-random/inkling-2", trust_remote_code=True)
model = AutoModelForMultimodalLM.from_pretrained("tiny-random/inkling-2", trust_remote_code=True, device_map="auto")
messages = [
    {
        "role": "user",
        "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?"}
        ]
    },
]
inputs = processor.apply_chat_template(
	messages,
	add_generation_prompt=True,
	tokenize=True,
	return_dict=True,
	return_tensors="pt",
).to(model.device)

outputs = model.generate(**inputs, max_new_tokens=256)

Example usage

Transformers (unverified)

Install Transformers with Inkling 2 support. The bundled loader expands packed expert weights to BF16.

def run_transformers(model_id: str):
    import torch
    from PIL import Image
    from transformers import AutoModelForImageTextToText, AutoProcessor

    processor = AutoProcessor.from_pretrained(model_id)
    model = AutoModelForImageTextToText.from_pretrained(
        model_id, trust_remote_code=True, dtype=torch.bfloat16, device_map="cuda"
    )
    image = Image.new("RGB", (80, 80), (80, 120, 160))
    inputs = processor(text=f"{processor.image_token}Describe this image.", images=image, return_tensors="pt").to(
        model.device
    )
    with torch.inference_mode():
        output = model.generate(**inputs, max_new_tokens=10, min_new_tokens=10, do_sample=False)
    print(processor.batch_decode(output[:, inputs.input_ids.shape[1] :], skip_special_tokens=True))


if __name__ == "__main__":
    run_transformers(model_id="tiny-random/inkling-2")

SGLang serving (unverified)

Use the pinned SGLang version and the bundled small-matrix kernel plugin.

SGLANG_BUILD_RUST_EXTS=none pip install 'git+https://github.com/sgl-project/sglang.git@f726172d760dea737c7f1e797c9f32efe14d1685#subdirectory=python'
