From the model card
SenseNova-U1.5-8B-MoT is our latest native unified multimodal checkpoint for more accurate, consistent, reliable, and aesthetically compelling visual creation. Built on NEO-unify, it strengthens the patchify layers, data quality and distribution, task formulation, prompt enhancement, and post-training pipeline.
The official release focuses on six user-visible improvements:
The reference inference implementation is available in the SenseNova-U1 GitHub repository.
git clone https://github.com/OpenSenseNova/SenseNova-U1.git
cd SenseNova-U1
uv sync
source .venv/bin/activate
The upstream environment uses Python 3.11, PyTorch 2.8, and CUDA 12.8. For other CUDA versions and optional FlashAttention configurations, see the installation guide.
python examples/t2i/inference.py \
--model_path sensenova/SenseNova-U1.5-8B-MoT \
--prompt "A cinematic mountain lake at sunrise, realistic photography." \
--width 2048 --height 2048 \
--device_map auto \
--output output.png
python examples/editing/inference.py \
--model_path sensenova/SenseNova-U1.5-8B-MoT \

--prompt "Change the jacket to cobalt blue. Preserve the face, pose, background, lighting, and framing." \
--output edited.png
See the inference examples for more options, supported resolutions, and batch processing.
Direct natural-language prompts work well for clear tasks with few constraints. For complex generation or editing, use prompt enhancement when additional planning is needed and explicitly specify what should remain unchanged.
See the SenseNova-U1.5 Cookbook for setup instructions and optional Image PE, Caption-to-Prompt, and Editing PE recipes.
The fastest way to experience SenseNova-U1.5 is through SenseNova-Studio — a 🆓 free online playground where you can try the model directly in your browser, no installation or GPU required.
The official release improves upon the Preview, though challenges remain in:
