It works well in places like healthcare, e-commerce, education, and AI-powered systems that require users to be able to think in more than one way. It pioneers intelligent, image-aware interactions by combining visual perception with high-quality conversational AI. 

Quick-Start Guide: Running DeepSeek-VL2

Here are the steps you need to take to set up and run inference with DeepSeek-VL2. 

1. Install Dependencies 

You need Python and PyTorch to use DeepSeek-VL2. Install the dependencies you need by: 

pip install torch torchvision torchaudio
pip install transformers accelerate einops safetensors

2. Load the Model

The script below shows how to use Hugging Face's transformers library to load the DeepSeek-VL2 model.

from transformers import AutoProcessor, AutoModelForVision2Seq
import torch
from PIL import Image

# Load processor and model
model_path = "deepseek-ai/deepseek-vl2-7b-chat"
processor = AutoProcessor.from_pretrained(model_path)
model = AutoModelForVision2Seq.from_pretrained(model_path, torch_dtype=torch.float16, device_map="auto")

# Set model to evaluation mode
model.eval()

3. Perform Image Captioning

You can generate captions for images using DeepSeek-VL2:

# Load an image
image_path = "sample_image.jpg"
image = Image.open(image_path).convert("RGB")

# Define prompt
prompt = "Describe this image in detail."

# Process inputs
inputs = processor(image, prompt, return_tensors="pt").to("cuda")

# Generate response
output = model.generate(**inputs, max_new_tokens=100)
caption = processor.batch_decode(output, skip_special_tokens=True)[0]

print("Generated Caption:", caption)

4. Visual Question Answering (VQA)

DeepSeek-VL2 can answer questions related to an image.

# Define a visual question
question = "What is happening in this image?"

# Process inputs
inputs = processor(image, question, return_tensors="pt").to("cuda")

# Generate response
output = model.generate(**inputs, max_new_tokens=100)
answer = processor.batch_decode(output, skip_special_tokens=True)[0]

print("VQA Answer:", answer)

Performance and Applications
