### Example usage
#### Transformers (✅ verified)
The example sends one image and one predecoded video. The Qwen3.5 linear-attention path requires CUDA and Triton. Install `transformers[torch]>=5.18.0` and `Pillow`.
```python
def run_transformers(model_id: str):
import numpy as np
import torch
from PIL import Image, ImageDraw
from transformers import AutoModelForImageTextToText, AutoProcessor
from transformers.video_utils import VideoMetadata
model_id = str(model_id)
processor = AutoProcessor.from_pretrained(model_id, trust_remote_code=True)
model = AutoModelForImageTextToText.from_pretrained(
model_id,
dtype=torch.bfloat16,
device_map="cuda",
attn_implementation="sdpa",
)
image = Image.new("RGB", (448, 448), "white")
ImageDraw.Draw(image).text((20, 20), "Hello", fill="black")
frames = np.stack(
[
np.asarray(Image.new("RGB", (64, 64), color))
for color in ((220, 30, 30), (30, 220, 30), (30, 30, 220), (220, 220, 30))
]
)
messages = [

"content": [
{"type": "image", "image": image},
{"type": "video", "video": frames},
{"type": "text", "text": "Describe the image and the video."},
],
}
]

with torch.no_grad():
logits = model(**inputs).logits
assert torch.isfinite(logits).all()
output = model.generate(**inputs, downsample_mode="16x", do_sample=False, max_new_tokens=10)
print(processor.decode(output[0, inputs["input_ids"].shape[1] :], skip_special_tokens=True))
