MingTok introduces the first continuous unified tokenizer for vision, enabling seamless integration of image understanding and generation within a single framework. This innovation leads to 3.5x faster convergence by aligning semantic understanding and generative dynamics, allowing for efficient multi-turn interactions without the costly detours seen in previous models. Ming-UniVision, built on MingTok, effectively harmonizes these tasks, paving the way for more intuitive multimodal AI systems.
