MoVA-8B Model Card

Model details

Model type: MoVA-8B is an open-source multimodal large language model (MLLM), adaptively routing and fusing task-specific vision experts with a coarse-to-fine mechanism.

Vision Encoders: OpenAI-CLIP-336px, DINOv2-giant, Co-DETR-large, SAM-huge, Vary-base, Pix2Struct-large, Deplot-base, and BiomedCLIP-base.

Base LLM: meta-llama/Meta-Llama-3-8B-Instruct

Training dataset

15M diverse visual instruction tuning samples for pre-training, including DataComp-1B, ShareGPT4V-PT, Objects365, and MMC-Instruction. Please refer to our paper for more details.
2M high-quality instruction data for fine-tuning. We integrate several visual question answering datasets across various domains, such as DocVQA, ChartQA, InfographicVQA, AI2D, ST-VQA, TextVQA, SynthDoG-en, Geometry3K, PGPS9K, Geo170K, VQA-RAD, and SLAKE into LLaVA-mix-665k. We also encompass equivalent comprehensive captions generated by GPT4-V.

Evaluation dataset

We evaluate our model on a wide range of popular MLLM benchmarks.
