DeepSeek-VL: Towards Real-World Vision-LanguageUnderstanding
This is the transformers version of Deepseek-VL, a foundation model for Visual Language Modeling.
Table of Contents
Model Details
Deepseek-VL was introduced by the DeepSeek AI team. It is a vision-language model (VLM) designed to process both text and images for generating contextually relevant responses. The model leverages LLaMA as its text encoder, while SigLip is used for encoding images.
The abstract from the paper is the following:
We present DeepSeek-VL, an open-source Vision-Language (VL) Model designed for real-world vision and language understanding applications. Our approach is structured around three key dimensions: We strive to ensure our data is diverse, scalable, and extensively covers real-world scenarios including web screenshots, PDFs, OCR, charts, and knowledge-based content, aiming for a comprehensive representation of practical contexts. Further, we create a use case taxonomy from real user scenarios and construct an instruction tuning dataset accordingly. The fine-tuning with this dataset substantially improves the model's user experience in practical applications. Considering efficiency and the demands of most real-world scenarios, DeepSeek-VL incorporates a hybrid vision encoder that efficiently processes high-resolution images (1024 x 1024), while maintaining a relatively low computational overhead. This design choice ensures the model's ability to capture critical semantic and detailed information across various visual tasks. We posit that a proficient Vision-Language Model should, foremost, possess strong language abilities. To ensure the preservation of LLM capabilities during pretraining, we investigate an effective VL pretraining strategy by integrating LLM training from the beginning and carefully managing the competitive dynamics observed between vision and language modalities. The DeepSeek-VL family (both 1.3B and 7B models) showcases superior user experiences as a vision-language chatbot in real-world applications, achieving state-of-the-art or competitive performance across a wide range of visual-language benchmarks at the same model size while maintaining robust performance on language-centric benchmarks. We have made both 1.3B and 7B models publicly accessible to foster innovations based on this foundation model.

How to Get Started with the Model
Note: Ensure you have
transformersversion 4.54.0 or later installed:pip install -U "transformers>=4.54.0"
The example below demonstrates how to generate text based on an image with Pipeline.
import torch
from transformers import pipeline
pipe = pipeline(
task="image-text-to-text",
model="deepseek-community/deepseek-vl-1.3b-chat",
device=0,
torch_dtype=torch.float16
)
messages = [
{
"role": "user",
"content": [
{
"type": "image",
"url": "https://huggingface.co/datasets/huggingface/documentation-images/resolve/main/pipeline-cat-chonk.jpeg",
},
{ "type": "text", "text": "Describe this image."},
]
}
]
pipe(text=messages, max_new_tokens=20, return_full_text=False)
Generate text based on an image with AutoModel.
import torch
from transformers import DeepseekVLForConditionalGeneration, AutoProcessor
model = DeepseekVLForConditionalGeneration.from_pretrained(
"deepseek-community/deepseek-vl-1.3b-chat",
torch_dtype=torch.float16,
device_map="auto",
attn_implementation="sdpa"
)
processor = AutoProcessor.from_pretrained("deepseek-community/deepseek-vl-1.3b-chat")
messages = [
{
"role":"user",
"content":[
{
"type":"image",
"url": "https://huggingface.co/datasets/huggingface/documentation-images/resolve/main/pipeline-cat-chonk.jpeg"
},
{
"type":"text",
"text":"Describe this image."
}
]
}
]
inputs = processor.apply_chat_template(
messages,
add_generation_prompt=True,
tokenize=True,
return_dict=True,
return_tensors="pt"
).to(model.device, dtype=model.dtype)
generated_ids = model.generate(**inputs, max_new_tokens=128)
generated_ids_trimmed = [
out_ids[len(in_ids) :] for in_ids, out_ids in zip(inputs.input_ids, generated_ids)
]
output_text = processor.batch_decode(
generated_ids_trimmed, skip_special_tokens=True, clean_up_tokenization_spaces=False
)
print(output_text)
Quantization reduces the memory burden of large models by representing the weights in a lower precision. Refer to the Quantization overview for more available quantization backends.
The example below uses TorchAo to only quantize the weights to int4.
import torch
from transformers import TorchAoConfig, DeepseekVLForConditionalGeneration, AutoProcessor
quantization_config = TorchAoConfig(
"int4_weight_only",
group_size=128
)
model = DeepseekVLForConditionalGeneration.from_pretrained(
"deepseek-community/deepseek-vl-1.3b-chat",
torch_dtype=torch.bfloat16,
device_map="auto",
quantization_config=quantization_config
)
Do inference with multiple images in a single conversation.
import torch
from transformers import DeepseekVLForConditionalGeneration, AutoProcessor
model = DeepseekVLForConditionalGeneration.from_pretrained(
"deepseek-community/deepseek-vl-1.3b-chat",
torch_dtype=torch.float16,
device_map="auto",
attn_implementation="sdpa"
)
processor = AutoProcessor.from_pretrained("deepseek-community/deepseek-vl-1.3b-chat")
messages = [

"content": [
{"type": "text", "text": "What’s the difference between"},
{"type": "image", "url": "http://images.cocodataset.org/val2017/000000039769.jpg"},

print(output_text)
Training Details
Training Data
The Deepseek-VL model was trained on the following datasets:
Training Pipeline
Training pipelines consist of three stages.
- Stage 1 involves training the Vision-Language (VL) adaptor while keeping the hybrid vision encoder and language model fixed.
- Stage 2 is the crucial part of the joint vision and language pretraining, where both VL adaptor and language model are trainable.
- Stage 3 is the supervised fine-tuning phase, during which the low-resolution vision encoder SigLIP-L, VL adaptor, and language model will be trained
