Granite 4.0 1B
Analysis Summary
Granite 4.0 1B is IBM's smallest Granite 4.0 model, released October 2025. At 1B parameters, its intelligence index of 2.1 and MMLU-Pro of 32.5% reflect the inherent limitations of very small models. The agentic index of 22.8 is surprisingly reasonable for this size class, suggesting some tool-use capability has been optimised. Coding (LiveCodeBench 4.7%) and math (6.3%) are very limited.
For businesses, this model is only appropriate for highly constrained edge or embedded deployments where model size is the overriding concern. It is not suitable for any production business workflow requiring meaningful reasoning, coding, or content generation. IBM's enterprise backing may provide integration advantages in specific environments.
Teams exploring on-device or IoT-adjacent AI applications may find it a starting point, but the capability ceiling is low and most business tasks will require a significantly larger model.
