InternVL-U: Open-Source 4B Unified Model for Reasoning, Generation, and Editing
AIInternVL-U is a lightweight 4B unified multimodal model that combines reasoning, generation, and editing in one framework, according to Intern Large Models. The post says it uses unified contextual modeling, modality-specific modular design, and decoupled visual representations to balance performance and efficiency. It reportedly outperforms unified baselines more than 3× its size on text rendering, scientific reasoning, and spatially grounded generation and editing, and is open-source on GitHub and Hugging Face.
