How to use ClareNie/Light-Omni with Transformers:
# Use a pipeline as a high-level helper
from transformers import pipeline
pipe = pipeline("image-text-to-text", model="ClareNie/Light-Omni")
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) # Load model directly
from transformers import AutoProcessor, AutoModelForMultimodalLM
processor = AutoProcessor.from_pretrained("ClareNie/Light-Omni")
model = AutoModelForMultimodalLM.from_pretrained("ClareNie/Light-Omni")
messages = [
{

]
},
]
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=40)
print(processor.decode(outputs[0][inputs["input_ids"].shape[-1]:]))How to use ClareNie/Light-Omni with vLLM:

Light-Omni is a multimodal agent framework for reflexive video understanding with long-term memory. It replaces costly detective-style iterative reasoning with dual contextual states: a compact global state consolidated from episodic memory, and a latent state that drives action control and semantically aligned retrieval.
This repository hosts the Light-Omni model checkpoint for inference. It contains the safetensors weight shards, tokenizer files, model configuration, and multimodal preprocessor configuration files.
