-## 1. Introduction
-
-Introducing DeepSeek-VL2, an advanced series of large Mixture-of-Experts (MoE) Vision-Language Models that significantly improves upon its predecessor, DeepSeek-VL. DeepSeek-VL2 demonstrates superior capabilities across various tasks, including but not limited to visual question answering, optical character recognition,  document/table/chart understanding, and visual grounding. Our model series is composed of three variants: DeepSeek-VL2-Tiny, DeepSeek-VL2-Small and DeepSeek-VL2, with 1.0B, 2.8B and 4.5B activated parameters respectively.
-DeepSeek-VL2 achieves competitive or state-of-the-art performance with similar or fewer activated parameters compared to existing open-source dense and MoE-based models.

-## 4. Quick Start
-
-### Installation
-
-On the basis of `Python >= 3.8` environment, install the necessary dependencies by running the following command:
-
-```shell
-pip install -e .
-```
-
-### Simple Inference Example with One Image
-
-**Note: You may need 80GB GPU memory to run this script with deepseek-vl2-small and even larger for deepseek-vl2.**
-
-```python
-import torch
-from transformers import AutoModelForCausalLM
-
-from deepseek_vl2.models import DeepseekVLV2Processor, DeepseekVLV2ForCausalLM
-from deepseek_vl2.utils.io import load_pil_images
-
-
-# specify the path to the model
-model_path = "deepseek-ai/deepseek-vl2-tiny"
-vl_chat_processor: DeepseekVLV2Processor = DeepseekVLV2Processor.from_pretrained(model_path)
-tokenizer = vl_chat_processor.tokenizer
-
-vl_gpt: DeepseekVLV2ForCausalLM = AutoModelForCausalLM.from_pretrained(model_path, trust_remote_code=True)
-vl_gpt = vl_gpt.to(torch.bfloat16).cuda().eval()
-
-## single image conversation example
-## Please note that <|ref|> and <|/ref|> are designed specifically for the object localization feature. These special tokens are not required for normal conversations.
-## If you would like to experience the grounded captioning functionality (responses that include both object localization and reasoning), you need to add the special token <|grounding|> at the beginning of the prompt. Examples could be found in Figure 9 of our paper.
-conversation = [
-    {
-        "role": "<|User|>",
-        "content": "<image>\n<|ref|>The giraffe at the back.<|/ref|>.",
-        "images": ["./images/visual_grounding_1.jpeg"],
-    },
-    {"role": "<|Assistant|>", "content": ""},
-]
-
-# load images and prepare for inputs
-pil_images = load_pil_images(conversation)
-prepare_inputs = vl_chat_processor(
-    conversations=conversation,
-    images=pil_images,
-    force_batchify=True,
-    system_prompt=""
-).to(vl_gpt.device)
-
-# run image encoder to get the image embeddings
-inputs_embeds = vl_gpt.prepare_inputs_embeds(**prepare_inputs)
-
-# run the model to get the response
-outputs = vl_gpt.language.generate(
-    inputs_embeds=inputs_embeds,
-    attention_mask=prepare_inputs.attention_mask,
-    pad_token_id=tokenizer.eos_token_id,
-    bos_token_id=tokenizer.bos_token_id,
-    eos_token_id=tokenizer.eos_token_id,
-    max_new_tokens=512,
-    do_sample=False,
-    use_cache=True
-)
-
-answer = tokenizer.decode(outputs[0].cpu().tolist(), skip_special_tokens=False)
-print(f"{prepare_inputs['sft_format'][0]}", answer)
-```
-
-And the output is something like:
-```
-<|User|>: <image>
-<|ref|>The giraffe at the back.<|/ref|>.
-
-<|Assistant|>: <|ref|>The giraffe at the back.<|/ref|><|det|>[[580, 270, 999, 900]]<|/det|><｜end▁of▁sentence｜>
-```
-
-### Simple Inference Example with Multiple Images
-
-**Note: You may need 80GB GPU memory to run this script with deepseek-vl2-small and even larger for deepseek-vl2.**
-
-```python
-import torch
-from transformers import AutoModelForCausalLM
-
-from deepseek_vl2.models import DeepseekVLV2Processor, DeepseekVLV2ForCausalLM
-from deepseek_vl2.utils.io import load_pil_images
-
-
-# specify the path to the model
-model_path = "deepseek-ai/deepseek-vl2-tiny"
-vl_chat_processor: DeepseekVLV2Processor = DeepseekVLV2Processor.from_pretrained(model_path)
-tokenizer = vl_chat_processor.tokenizer
-
-vl_gpt: DeepseekVLV2ForCausalLM = AutoModelForCausalLM.from_pretrained(model_path, trust_remote_code=True)
-vl_gpt = vl_gpt.to(torch.bfloat16).cuda().eval()
-
-# multiple images/interleaved image-text
-conversation = [
-    {
-        "role": "<|User|>",
-        "content": "This is image_1: <image>\n"
-                   "This is image_2: <image>\n"
-                   "This is image_3: <image>\n Can you tell me what are in the images?",
-        "images": [
-            "images/multi_image_1.jpeg",
-            "images/multi_image_2.jpeg",
-            "images/multi_image_3.jpeg",
-        ],
-    },
-    {"role": "<|Assistant|>", "content": ""}
-]
-
-# load images and prepare for inputs
-pil_images = load_pil_images(conversation)
-prepare_inputs = vl_chat_processor(
-    conversations=conversation,
-    images=pil_images,
-    force_batchify=True,
-    system_prompt=""
-).to(vl_gpt.device)
-
-# run image encoder to get the image embeddings
-inputs_embeds = vl_gpt.prepare_inputs_embeds(**prepare_inputs)
-
-# run the model to get the response
-outputs = vl_gpt.language.generate(
-    inputs_embeds=inputs_embeds,
-    attention_mask=prepare_inputs.attention_mask,
-    pad_token_id=tokenizer.eos_token_id,
-    bos_token_id=tokenizer.bos_token_id,
-    eos_token_id=tokenizer.eos_token_id,
-    max_new_tokens=512,
-    do_sample=False,
-    use_cache=True
-)
-
-answer = tokenizer.decode(outputs[0].cpu().tolist(), skip_special_tokens=False)
-print(f"{prepare_inputs['sft_format'][0]}", answer)
-```
-
-And the output is something like:
-```
-<|User|>: This is image_1: <image>
-This is image_2: <image>
-This is image_3: <image>
- Can you tell me what are in the images?
-
-<|Assistant|>: The images show three different types of vegetables. Image_1 features carrots, which are orange with green tops. Image_2 displays corn cobs, which are yellow with green husks. Image_3 contains raw pork ribs, which are pinkish-red with some marbling.<｜end▁of▁sentence｜>
-```
-
-### Simple Inference Example with Incremental Prefilling
-
-**Note: We use incremental prefilling to inference within 40GB GPU using deepseek-vl2-small.**
-
-```python
-import torch
-from transformers import AutoModelForCausalLM
-
-from deepseek_vl2.models import DeepseekVLV2Processor, DeepseekVLV2ForCausalLM
-from deepseek_vl2.utils.io import load_pil_images
-
-
-# specify the path to the model
-model_path = "deepseek-ai/deepseek-vl2-small"
-vl_chat_processor: DeepseekVLV2Processor = DeepseekVLV2Processor.from_pretrained(model_path)
-tokenizer = vl_chat_processor.tokenizer
-
-vl_gpt: DeepseekVLV2ForCausalLM = AutoModelForCausalLM.from_pretrained(model_path, trust_remote_code=True)
-vl_gpt = vl_gpt.to(torch.bfloat16).cuda().eval()
-
-# multiple images/interleaved image-text
-conversation = [
-    {
-        "role": "<|User|>",
-        "content": "This is image_1: <image>\n"
-                   "This is image_2: <image>\n"
-                   "This is image_3: <image>\n Can you tell me what are in the images?",
-        "images": [
-            "images/multi_image_1.jpeg",
-            "images/multi_image_2.jpeg",
-            "images/multi_image_3.jpeg",
-        ],
-    },
-    {"role": "<|Assistant|>", "content": ""}
-]
-
-# load images and prepare for inputs
-pil_images = load_pil_images(conversation)
-prepare_inputs = vl_chat_processor(
-    conversations=conversation,
-    images=pil_images,
-    force_batchify=True,
-    system_prompt=""
-).to(vl_gpt.device)
-
-with torch.no_grad():
-    # run image encoder to get the image embeddings
-    inputs_embeds = vl_gpt.prepare_inputs_embeds(**prepare_inputs)
-
-    # incremental_prefilling when using 40G GPU for vl2-small
-    inputs_embeds, past_key_values = vl_gpt.incremental_prefilling(
-        input_ids=prepare_inputs.input_ids,
-        images=prepare_inputs.images,
-        images_seq_mask=prepare_inputs.images_seq_mask,
-        images_spatial_crop=prepare_inputs.images_spatial_crop,
-        attention_mask=prepare_inputs.attention_mask,
-        chunk_size=512 # prefilling size
-    )
-
-    # run the model to get the response
-    outputs = vl_gpt.generate(
-        inputs_embeds=inputs_embeds,
-        input_ids=prepare_inputs.input_ids,
-        images=prepare_inputs.images,
-        images_seq_mask=prepare_inputs.images_seq_mask,
-        images_spatial_crop=prepare_inputs.images_spatial_crop,
-        attention_mask=prepare_inputs.attention_mask,
-        past_key_values=past_key_values,
-
-        pad_token_id=tokenizer.eos_token_id,
-        bos_token_id=tokenizer.bos_token_id,
-        eos_token_id=tokenizer.eos_token_id,
-        max_new_tokens=512,
-
-        do_sample=False,
-        use_cache=True,
-    )
-
-    answer = tokenizer.decode(outputs[0][len(prepare_inputs.input_ids[0]):].cpu().tolist(), skip_special_tokens=False)
-
-print(f"{prepare_inputs['sft_format'][0]}", answer)
-```
-
-And the output is something like:
-```
-<|User|>: This is image_1: <image>
-This is image_2: <image>
-This is image_3: <image>
- Can you tell me what are in the images?
-
-<|Assistant|>: The first image contains carrots. The second image contains corn. The third image contains meat.<｜end▁of▁sentence｜>
-```
-
-### Full Inference Example
-```shell
-# without incremental prefilling
-CUDA_VISIBLE_DEVICES=0 python inference.py --model_path "deepseek-ai/deepseek-vl2"
-
-# with incremental prefilling, when using 40G GPU for vl2-small
-CUDA_VISIBLE_DEVICES=0 python inference.py --model_path "deepseek-ai/deepseek-vl2-small" --chunk_size 512
-
-```
-
-
-### Gradio Demo
-
-* Install the necessary dependencies:
-```shell
-pip install -e .[gradio]
-```
-
-* then run the following command:
-
-```shell
-# vl2-tiny, 3.37B-MoE in total, activated 1B, can be run on a single GPU < 40GB
-CUDA_VISIBLE_DEVICES=2 python web_demo.py \
---model_name "deepseek-ai/deepseek-vl2-tiny"  \
---port 37914
-
-
-# vl2-small, 16.1B-MoE in total, activated 2.4B
-# If run on A100 40GB GPU, you need to set the `--chunk_size 512` for incremental prefilling for saving memory and it might be slow.
-# If run on > 40GB GPU, you can ignore the `--chunk_size 512` for faster response.
-CUDA_VISIBLE_DEVICES=2 python web_demo.py \
---model_name "deepseek-ai/deepseek-vl2-small"  \
---port 37914 \
---chunk_size 512
-
-# # vl27.5-MoE in total, activated 4.2B
-CUDA_VISIBLE_DEVICES=2 python web_demo.py \
---model_name "deepseek-ai/deepseek-vl2"  \
---port 37914
-```
-
-* **Important**: This is a basic and native demo implementation without any deployment optimizations, which may result in slower performance. For production environments, consider using optimized deployment solutions, such as vllm, sglang, lmdeploy, etc. These optimizations will help achieve faster response times and better cost efficiency.
