Granite 4.0 1B
Analysis Summary
Granite 4.0 1B is IBM's smallest parameter-count model in the Granite 4.0 family, with an intelligence index of 7.3 and a coding index of 2.9. Its most notable metric is the agentic index of 22.8, which is unusually high for a 1B model and likely reflects targeted tool-use training rather than broad capability.
In practice, MMLU Pro at 0.325 and livecodebench at 0.047 confirm that general reasoning and code generation are very limited. Instruction following (ifbench 0.205) and long-context reliability (lcr 0.04) are both weak. No pricing data is available.
Granite 4.0 1B is best understood as an on-device or embedded inference model for highly constrained environments. It is not suitable for client-facing content, coding assistance, or any workflow requiring reliable reasoning. Teams exploring ultra-small model deployment for specific classification or routing tasks may find it a useful baseline.

Editorial notes
Granite 4.0 1B is IBM's 1-billion-parameter model with a surprisingly high agentic index for its size, but very limited reasoning and coding capability make it unsuitable for substantive business tasks.
