LLaVA-UHD-v3: PROGRESSIVE VISUAL COMPRES-SION FOR EFFICIENT NAIVE-RESOLUTION ENCODING IN MLLMS

🚀 Github | 📄 Arxiv

We release LLaVA-UHD-v3, a multimodal large language model (MLLM) built upon our proposed Progressive Visual Compression (PVC) for efficient naive-resolution encoding. Our model not only achieves performance comparable to advanced MLLMs like Qwen2-VL across 15 diverse benchmarks but also delivers a 1.9x reduction in Time-to-First-Token (TTFT). Moreover, LLaVA-UHD v3 can be trained efficiently in academic settings, requiring approximately 300 hours on 32 A100 GPUs.

Quick Start

pip install "transformers>=4.51.0"

We adapt our model with transformers, here we show a example of how to chat with our LLaVA-UHD-v3 conveniently.

Using 🤗 Transformers to Chat

from transformers import AutoModelForCasualLM, AutoProcessor

# default: Load the model on the available device(s)
model = AutoModelForImageTextToText.from_pretrained(
    "Sishxo/LLaVA-UHD-v3", dtype="auto", device_map="auto"
)

# We recommend enabling flash_attention_2 for better acceleration and memory saving, especially in multi-image and video scenarios.
# model = AutoModelForImageTextToText.from_pretrained(
#     "Sishxo/LLaVA-UHD-v3",
#     dtype=torch.bfloat16,
#     attn_implementation="flash_attention_2",
#     device_map="auto",
# )

processor = AutoProcessor.from_pretrained("Sishxo/LLaVA-UHD-v3")

messages = [
    {
        "role": "user",
        "content": [
            {"type": "image", "image": "file:///path/to/your/image.jpg"},
            {"type": "text", "text": "Describe this image."},
        ],
    }
]

# Preparation for inference
inputs = processor.apply_chat_template(
    messages,
    tokenize=True,
    add_generation_prompt=True,
    return_dict=True,
    return_tensors="pt"
)
inputs = inputs.to(model.device)

# Inference: Generation of the output
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)

Highlights

🧠 Progressive Visual Compression (PVC): LLaVA-UHD v3 introduces a novel visual encoding strategy for efficient naive-resolution processing in MLLMs, combining fine-grained tokenization with hierarchical compression.

💡 Refined Patch Embedding (RPE): Flexibly scales patch sizes to produce detailed visual tokens while maintaining full compatibility with pretrained Vision Transformers, enabling richer visual representations.

💡 Windowed Token Compression (WTC): Progressively merges local token representations within the vision encoder, reducing sequence length and computational cost without losing holistic visual context.

🏆 Preserved Holistic Understanding: Unlike slice-based approaches, PVC maintains full-scene semantics, preventing fragmented interpretations common in other naive-resolution encoding methods.

⚡ Efficient and Competitive: Achieves strong performance on a wide range of vision-language benchmarks, rivaling state-of-the-art models like Qwen2-VL, while significantly lowering inference latency.

This repository provides examples, usage instructions, and best practices to help developers leverage LLaVA-UHD v3 for efficient, high-fidelity vision-language tasks.
