LLaVA-OneVision-1.5: Fully Open-Source State-of-the-Art VLM Model

✨ Key Features

LLaVA-OneVision-1.5 introduces a novel family of fully open-source Large Multimodal Models (LMMs) that achieves state-of-the-art performance with substantially lower cost through training on native resolution images.

1. Superior Performance A family of fully open-source large multimodal models demonstrating superior performance across multiple multimodal benchmarks, outperforming Qwen2.5-VL in most evaluation tasks.

2. High-Quality Data at Scale Meticulously curated mid-training and SFT data with rigorous filtering and quality control.

• Concept-balanced, highly diverse, high-quality caption data
• Comprehensive instruction fine-tuning data covering a wide range of tasks

3. Ultra-Efficient Training Framework Complete end-to-end training framework designed for maximum efficiency:

• $16K total budget for full model training
• 45% HFU efficiency on A100 GPUs ($0.6 per GPU/Hour)
• Built on MegatronLM with support for MoE, FP8, and long sequence parallelization
• Optimized codebase for cost-effective scaling

4. Fully Open Framework for community access and reproducibility:

• ✅ High-quality mid-training & SFT data
• ✅ Complete training framework & code
• ✅ Training recipes & configurations
• ✅ Base & instruct model checkpoints
• ✅ Comprehensive training logs & metrics

Code

This model is trained using a fully open-source, end-to-end training framework, with all code available at EvolvingLMMs-Lab/LLaVA-OneVision-1.5.

Using 🤗 Transformers to Chat

Here we show a code snippet to show you how to use the chat model with transformers and qwen_vl_utils:

from transformers import AutoTokenizer, AutoProcessor, AutoModelForCausalLM
from qwen_vl_utils import process_vision_info
model_path = "lmms-lab/LLaVA-One-Vision-1.5-8B-Instruct"

# default: Load the model on the available device(s)
model = AutoModelForCausalLM.from_pretrained(
    model_path, torch_dtype="auto", device_map="auto", trust_remote_code=True
)

# default processer
processor = AutoProcessor.from_pretrained(model_path, trust_remote_code=True)

messages = [
    {
        "role": "user",
        "content": [
            {
                "type": "image",
                "image": "https://qianwen-res.oss-cn-beijing.aliyuncs.com/Qwen-VL/assets/demo.jpeg",
            },
            {"type": "text", "text": "Describe this image."},
        ],
    }
]

# Preparation for inference
text = processor.apply_chat_template(
    messages, tokenize=False, add_generation_prompt=True
)
image_inputs, video_inputs = process_vision_info(messages)
inputs = processor(
    text=[text],
    images=image_inputs,
    videos=video_inputs,
    padding=True,
    return_tensors="pt",
)
inputs = inputs.to("cuda")

# Inference: Generation of the output
generated_ids = model.generate(**inputs, max_new_tokens=1024)
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)
