This tiny model is for debugging. It is randomly initialized with the config adapted from google/gemma-3-27b-it.

Example usage:

python

from transformers import pipeline
model_id = "yujiepan/gemma-3-tiny-random"
pipe = pipeline(
    "image-text-to-text", model=model_id, device="cuda",
    trust_remote_code=True, max_new_tokens=3,
)
messages = [
    {
        "role": "system",
        "content": [{"type": "text", "text": "You are a helpful assistant."}]
    },
    {
        "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?"}
        ]
    }
]
output = pipe(text=messages, max_new_tokens=5)
print(output)
