Raon-VisionEncoder is a 1.14B-parameter vision-language foundation model by KRAFTON for image and text feature extraction. It supports zero-shot image classification, image-text retrieval, and native aspect ratio inference via NaFlex. Built on OpenCLIP with a LocCa (Localized CoCa) architecture and ViT-SO400M vision encoder.

Requirements

pip install torch torchvision timm transformers huggingface-hub safetensors ftfy

Quick Start

python

import torch
from transformers import AutoModel
from PIL import Image

# Load model + processor
model = AutoModel.from_pretrained("KRAFTON/Raon-VisionEncoder", trust_remote_code=True)
model = model.to(dtype=torch.bfloat16).eval()
processor = model.get_processor("KRAFTON/Raon-VisionEncoder")

# Encode image and text
img_inputs = processor(images=Image.open("assets/photo.jpg"))
txt_inputs = processor(text=["a cat", "a dog"])

with torch.no_grad():
    img_feat = model.encode_image(**img_inputs)
    txt_feat = model.encode_text(**txt_inputs)

    # Compute similarity with learned scale and bias
    logits = model.logit_scale.exp() * (img_feat @ txt_feat.T) + model.logit_bias
    probs = logits.softmax(dim=-1)
    print(probs)
