LLaVA-OneVision 1.5

LLaVA-OneVision 1.5 is a vision-language model combining a Rice ViT encoder with a Qwen3 language backbone, capable of handling both image and video understanding. NeMo AutoModel ships a custom NVIDIA implementation (LlavaOneVisionForConditionalGeneration) with FSDP2/HSDP support, LoRA fine-tuning and distributed training.


Task	Image-Text-to-Text
Architecture	`LlavaOneVisionForConditionalGeneration`
Parameters	4B · 8B
HF Org	lmms-lab

Available Models

LLaVA-OneVision 1.5 4B: Qwen3 4B text backbone + Rice ViT (1024 hidden, 24 layers)
LLaVA-OneVision 1.5 8B: Qwen3 8B text backbone + Rice ViT (1024 hidden, 24 layers)

Architecture

LlavaOneVisionForConditionalGeneration

Vision tower is the Rice Transformer: 14×14 patch embed with 2D RoPE, standard Transformer blocks (LayerNorm + Attention + MLP), and a 2×2 spatial Patch Merger that projects to the language-model hidden size.

Try with NeMo AutoModel

1. Install (full instructions):

$ pip install nemo-automodel

2. Clone the repo to get the example recipes:

$ git clone https://github.com/NVIDIA-NeMo/Automodel.git
$ cd Automodel

3. Run the recipe from inside the repo:

$ automodel --nproc-per-node=8 examples/vlm_finetune/llava_onevision/llava_ov_1_5_4b_finetune.yaml

Run with Docker

1. Pull the container and mount a checkpoint directory:

$ docker run --gpus all -it --rm \
>   --shm-size=8g \
>   -v $(pwd)/checkpoints:/opt/Automodel/checkpoints \
>   nvcr.io/nvidia/nemo-automodel:26.04.00

2. Navigate to the AutoModel directory (where the recipes are):

$ cd /opt/Automodel

3. Run the recipe:

$ automodel --nproc-per-node=8 examples/vlm_finetune/llava_onevision/llava_ov_1_5_4b_finetune.yaml
