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

**LLaVA-OneVision1.5** 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.

- **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.

- **High-Quality Data at Scale**
Meticulously curated **pre-training and SFT data** with rigorous filtering and quality control, achieving **superior data efficiency** with only **64B tokens**.
    - Concept-balanced, highly diverse, high-quality caption data
    - Comprehensive instruction fine-tuning data covering a wide range of tasks

- **Ultra-Efficient Training Framework** Complete end-to-end training framework designed for maximum efficiency:
    - $16000 total budget for full model training on A100 GPUs  ($0.6 per GPU/Hour)
    - 45% HFU efficiency in 8k context length
    - Built on **MegatronLM** with support for **MoE**, **FP8**, and **long sequence parallelization**
    - Optimized codebase for cost-effective scaling


- **Fully Open Framework** for community access and reproducibility:
    - High-quality pre-training & SFT data
    - Complete training framework & code
    - Training recipes & configurations
    - Comprehensive training logs & metrics
