Publisher-reported capabilities

Granite 4.2 3B is IBM's compact dense reasoning model for edge and resource-constrained deployments.
It supports a native 128K context window, reasoning-augmented tool calling, and switchable full, low-effort, and non-thinking modes.

Limitations and availability caveats

IBM says multilingual performance can vary relative to English.
The model may produce inaccurate, biased, or unsafe responses, and IBM recommends deployment alongside additional safety controls.

Measured Coverage and Estimates

Granite 4.2 3b has 7 of 30 tracked IQ benchmark inputs across 3 of 6 dimensions. Raw benchmark tables contain source-backed results only. Derived IQ combines all six dimensions using the shared scoring methodology, including estimates where direct coverage is incomplete.

Among dimensions with direct benchmark coverage, this profile's highest estimated scores are Programmatic Reasoning (IQ 101) and Academic Reasoning (IQ 99). These dimension estimates can include statistical adjustments or predecessor priors; they are not raw benchmark percentages or claims of real-world task success.

Benchmark versions, evaluation harnesses, and coverage affect comparisons; a missing result is not a score of zero. See the scoring methodology for estimation and uncertainty limits.
