OpenSenseNova/SenseNova-U1

What is it?

Key features

• 01Unified model for image understanding, text-to-image generation, and image editing
• 02Native interleaved image-text generation in a single flow
• 03Dedicated infographic model variants with text and layout editing
• 04GGUF quantized checkpoints and layer-offload modes for low-VRAM inference
• 05Full-parameter fine-tuning training code

Use cases

• Generating posters, infographics, or designs with legible Chinese and English text
• Editing existing images with natural-language instructions while preserving unedited regions
• Producing illustrated step-by-step tutorials that mix text and images
• Running multimodal inference on a single consumer GPU using quantized weights

Quick start

1. 1

   Install the Python dependencies

2. 2

   Run the text-to-image example with the Transformers quick start

   python examples/t2i/inference.py --model_path sensenova/SenseNova-U1.5-8B-MoT --prompt "A formal portrait depicts a man in 18th-century attire seated with a scroll, wearing a red cloak and ornate medals, against a classical landscape with ancient ruins and inscriptions." --output output.png

Things to know

• !The model is large (8B parameters), so running it locally needs a capable GPU or a quantized GGUF checkpoint.
• !The README lists known issues such as dense text errors, unstable human details, and over-saturated colors.

FAQ

What is SenseNova-U1?

Open-source native unified multimodal models from SenseNova that handle image understanding, text-to-image generation, and image editing in one architecture. SenseNova-U1 and U1.5 are multimodal model series built on the NEO-unify architecture, which removes the separate visual encoder and VAE used by many systems and models language and vision end-to-end. The models cover visual question answering, text-to-image generation, interleaved image-text output, and image editing, with additional checkpoints tuned for infographics and 8-step fast inference.

Is SenseNova-U1 free to use? What license does it have?

SenseNova-U1 is open source under the Apache-2.0 license. Check the license terms before using it in commercial products.

Is SenseNova-U1 still maintained?

Actively maintained. The last commit to SenseNova-U1 was on Oct 1, 2026.

What can I use SenseNova-U1 for?

Generating posters, infographics, or designs with legible Chinese and English text Editing existing images with natural-language instructions while preserving unedited regions Producing illustrated step-by-step tutorials that mix text and images Running multimodal inference on a single consumer GPU using quantized weights
