This update primarily focuses on enhancing the efficiency of the vision foundation model. We developed InternViT-300M-448px by distilling knowledge from the robust vision foundation model, InternViT-6B-448px-V1-5. Like its predecessor, InternViT-300M-448px features a dynamic input resolution of 448×448, with a basic tile size of 448×448. During training, it allows for 1 to 12 tiles, and expands to 1 to 40 tiles during testing. Additionally, it inherits the powerful robustness, OCR capability, and high-resolution processing capacity from InternViT-6B-448px-V1-5.

Model Details

• Model Type: vision foundation model, feature backbone
• Model Stats:
  • Params (M): 304
  • Image size: 448 x 448, training with 1 - 12 tiles
• Pretrain Dataset: LAION-en, LAION-zh, COYO, GRIT, COCO, TextCaps, Objects365, OpenImages, All-Seeing, Wukong-OCR, LaionCOCO-OCR, and other OCR-related datasets. To enhance the OCR capability of the model, we have incorporated additional OCR data alongside the general caption datasets. Specifically, we utilized PaddleOCR to perform Chinese OCR on images from Wukong and English OCR on images from LAION-COCO.

Model Usage (Image Embeddings)

import torch
from PIL import Image
from transformers import AutoModel, CLIPImageProcessor

model = AutoModel.from_pretrained(
    'OpenGVLab/InternViT-300M-448px',
    torch_dtype=torch.bfloat16,
    low_cpu_mem_usage=True,
    trust_remote_code=True).cuda().eval()

image = Image.open('./examples/image1.jpg').convert('RGB')

image_processor = CLIPImageProcessor.from_pretrained('OpenGVLab/InternViT-300M-448px')

pixel_values = image_processor(images=image, return_tensors='pt').pixel_values
pixel_values = pixel_values.to(torch.bfloat16).cuda()

outputs = model(pixel_values)
