What's new in POINTS?

Key Innovations

Strong Baseline: We integrate the most recent advancement in vision-language model, i.e., CapFusion, Dual Vision Encoder, and Dynamic High Resolution, into POINTS.
Pre-training Dataset Filtering: We propose to filter the pre-training dataset using perplexity as a metric. Utilizing this filtering strategy, we can significantly reduce the size of the pre-training dataset and improve the performance of the model.
Model Soup: We propose to apply model soup to models, fine-tuned with different visual instruction tuning datasets, which can further significantly improve the performance of the model.

How to use POINTS?

python

from transformers import AutoModelForCausalLM, AutoTokenizer
from transformers import CLIPImageProcessor
from PIL import Image
import torch
import requests
from io import BytesIO


image_url = 'https://github.com/user-attachments/assets/83258e94-5d61-48ef-a87f-80dd9d895524'
response = requests.get(image_url)
image_data = BytesIO(response.content)
pil_image = Image.open(image_data)
prompt = 'please describe the image in detail'
model_path = 'WePOINTS/POINTS-Yi-1-5-9B-Chat'
tokenizer = AutoTokenizer.from_pretrained(model_path)
model = AutoModelForCausalLM.from_pretrained(
    model_path, trust_remote_code=True, device_map='cuda').to(torch.bfloat16)
image_processor = CLIPImageProcessor.from_pretrained(model_path)
generation_config = {
    'max_new_tokens': 1024,
    'temperature': 0.0,
    'top_p': 0.0,
    'num_beams': 1,
}
res = model.chat(
    pil_image,
    prompt,
    tokenizer,
    image_processor,
    True,
    generation_config
)
print(res)
