Granite Vision 3.1

Granite Vision 3.1 is IBM's lightweight multimodal model for enterprise document intelligence, released January 31, 2025 under Apache 2.0. It combines a vision encoder with Granite 3.1-2B-Instruct and is tuned for reading tables and charts, OCR, and answering questions grounded in document content.

IBM's published numbers put it at or near the top of its size class on DocVQA (0.88), ChartQA (0.86), TextVQA (0.76), and OCRBench (0.75), matching or beating larger rivals in the 2B tier (vendor-reported). Like all Granite models it ships with enterprise-friendly governance, including dataset disclosure and indemnity protections through IBM's commercial offerings.
