ViTP-ViT-L-300M-Med

ViTP (Visual Instruction Pretraining) vision backbone — ViT-L 300M variant pretrained on medical imaging domain visual instruction data. Compatible with InternVisionModel from InternVL.

Model Details

• Architecture: InternVisionModel (ViT-L, 24 layers, 1024 hidden, 16 heads)
• Image size: 448×448
• Patch size: 14
• Domain: Medical imaging

Usage

The model repo includes the modeling code. Load with transformers (no ViTP repo needed):

from transformers import AutoModel, AutoImageProcessor
import torch

device = "cuda"
model = AutoModel.from_pretrained(
    "BiliSakura/ViTP-ViT-L-300M-Med",
    trust_remote_code=True,
    torch_dtype=torch.bfloat16,
    device_map=device,
).eval()

processor = AutoImageProcessor.from_pretrained("BiliSakura/ViTP-ViT-L-300M-Med")
pixel_values = processor(images="image.jpg", return_tensors="pt").pixel_values.to(device, model.dtype)

with torch.no_grad():
    outputs = model(pixel_values=pixel_values)

# Pooled CLS token: (1, 1024)
features = outputs.pooler_output
# Or full sequence: outputs.last_hidden_state
