Granite 4.1 3B
Granite 4.1 3B is the instruction-tuned version of the matching Granite 4.1 base. It supports text generation, retrieval-based answers, extraction, coding and tool use.
Model design and training
IBM uses supervised fine-tuning and reinforcement-learning alignment. The training data combines public permissively licensed instructions, internal synthetic examples and selected human-authored data. The card names 12 supported languages and fill-in-the-middle code completion.Granite 4.1 3B model card
Practical use
Practical guidance. The compact 4.1 checkpoint can support extraction and short business assistants where predictable output matters. Compare it with 4.2 on your actual prompts before changing a working deployment. Preserve a set of representative documents to expose changes in formatting and tool selection.
