InternVL-U is a 4B-parameter unified multimodal model (UMM) from OpenGVLab/Shanghai AI Laboratory that integrates multimodal understanding, reasoning, image generation, and image editing into a single framework. Released in March 2026, it democratizes omni-capable multimodal intelligence by combining state-of-the-art vision-language comprehension with generative capabilities, outperforming larger unified baselines at a compact parameter scale.
