Granite Vision 4.1

IBMOpen WeightsPending Human Review

Granite Vision 4.1 is IBM’s 4B vision-language model for technical document understanding. It generates language answers from images, charts, tables, and diagrams, combining a compact language backbone with a vision encoder. The release targets enterprise workflows where users need grounded extraction and interpretation, rather than image generation. Apache-licensed weights support private deployment. Its model card documents task-specific evaluation and deployment instructions; results on chart benchmarks should not be treated as guaranteed accuracy on arbitrary business documents.
