Libraries

How to use parsecai/gemma-3-4b-it with Transformers:

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

pipe = pipeline("image-text-to-text", model="parsecai/gemma-3-4b-it")
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("parsecai/gemma-3-4b-it")
model = AutoModelForMultimodalLM.from_pretrained("parsecai/gemma-3-4b-it", 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)
print(processor.decode(outputs[0][inputs["input_ids"].shape[-1]:]))

Gemma 3 4B (instruction-tuned), the openjev-sdk backbone

An unmodified copy of google/gemma-3-4b-it: same weights, tokenizer and configuration, byte for byte. It is the frozen backbone that openjev-sdk trains small decision heads on, and the SDK downloads it from here on first use.

pip install openjev-sdk
hf auth login            # after accepting the terms above
openjev tod train runs/my-dataset --out runs/my-model   # fetches this repo once

Models trained by the SDK record a content fingerprint of these files, so any identical copy works, including Google's original.
