IBM released Granite 4.0 3B Vision, a compact multimodal model optimized for enterprise document parsing, including complex tables and charts. Built on the Granite 4.0 Micro base model, it ships as a LoRA adapter to maintain modularity for text-only fallbacks. The release leverages ChartNet, a new 1.7 million-sample synthetic dataset, and a DeepStack architecture that routes visual features separately to preserve spatial precision and semantic understanding. On the ChartQA benchmark, the model achieves a state-of-the-art Chart2Summary score of 86.4%.
