[2026.04.30] Release the preview version of the 8-step inference model SenseNova-U1-8B-MoT-8step-preview. In most cases, the image generation quality of this model closely matches that of the base model (see comparison and existing issues). To test this model, you can use the inference scripts, but with the following parameters: --cfg_scale 1.0 --num_steps 8 .
[2026.04.27] Initial release of the weights for SenseNova-U1-8B-MoT-SFT and SenseNova-U1-8B-MoT.
[2026.04.27] Initial release of the inference code for SenseNova-U1.
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, we further strengthen the patchify layers, data quality and distribution, task formulation, prompt enhancement, and post-training pipeline.
The official release focuses on six user-visible improvements:
Generation Latency vs. Averaging Performance on OneIG (EN, ZH), LongText (EN, ZH), BizGenEval (Easy, Hard), CVTG, IGenBench and Qwen-Image-Bench.
Direct natural-language prompts work well for clear tasks with few constraints. For complex generation or editing, use PE when additional planning is needed, explicitly specify what should remain unchanged, and gradually lower cfg_scale if high-frequency details or colors become overemphasized. See the U1.5 Showcases and Best Practices guide for workflow recommendations, setup instructions, and visual comparisons. SenseNova U1.5 will also be available on SenseNova-Studio, where everyone can experience the model directly.

🚀 SenseNova-U1 is a new series of native multimodal models that unifies multimodal understanding, reasoning, and generation within a monolithic architecture. It marks a fundamental paradigm shift in multimodal AI: from modality integration to true unification. Rather than relying on adapters to translate between modalities, SenseNova-U1 models think-and-act across language and vision natively.
Unifying visual understanding and generation in an end-to-end architecture from pixel to word opens tremendous possibilities, enabling highly efficient and strong understanding, generation, and interleaved reasoning in a natively multimodal manner.
At the core of SenseNova-U1 is NEO-unify, a novel architecture designed from the first principles for multimodal AI: It eliminates both Visual Encoder (VE) and Variational Auto-Encoder (VAE) where pixel-word information are inherently and deeply correlated. Several important features are as follows:
Powered by this new core architecture, SenseNova-U1 delivers exceptional efficiency in multimodal learning:
Left: Generation Latency vs. Averaging Performance on OneIG (EN, ZH), LongText (EN, ZH), BizGenEval (Easy, Hard), CVTG and IGenBench.
Right: Generation Latency vs. Averaging Performance on Infographic Benchmarks, i.e., BizGenEval (Easy, Hard), and IGenBench.
🏆 Open-source SoTA in both understanding and generation: SenseNova-U1 sets a new standard for unified multimodal understanding and generation, achieving state-of-the-art performance among open-source models across a wide range of understanding, reasoning, and generation benchmarks.
📖 Native interleaved image-text generation: SenseNova-U1 can generate coherent interleaved text and images in a single flow with one model, enabling use cases such as practical guides and travel diaries that combine clear communication with vivid storytelling and transform complex information into intuitive visuals.
📰 High-density information rendering: SenseNova-U1 demonstrates strong capabilities in dense visual communication, generating richly structured layouts for knowledge illustrations, posters, presentations, comics, resumes, and other information-rich formats.
