The statements below are described in the cited primary documentation. They describe what the cited documentation says the model is, not an independent performance evaluation.
- Unified text, vision, and audio under a single autoregressive objective.
- DiNA (Discrete Native Autoregressive) shared discrete space.
- dNaViT for tokenization at arbitrary resolutions.
- 28x visual compression while maintaining generative quality.
- Built on LongCat-Flash-Lite MoE (A3B) backbone.
- Open-source tokenizers for community development.
Access and license
