Granite-4.0-H-350M· Grok 3 Mini

Quick Verdict

Pick Grok 3 Mini if you want the stronger benchmark profile. Granite-4.0-H-350M only becomes the better choice if you want the cheaper token bill or you would rather avoid the extra latency and token burn of a reasoning model.

Grok 3 Mini is clearly ahead on the aggregate, 49 to 24. The gap is large enough that you do not need to squint at the spreadsheet to see the difference.

Grok 3 Mini's sharpest advantage is in knowledge, where it averages 59.8 against 16.4. The single biggest benchmark swing on the page is MMLU-Pro, 12.1% to 78.9%.

Grok 3 Mini is also the more expensive model on tokens at $0.30 input / $0.50 output per 1M tokens, versus $0.00 input / $0.00 output per 1M tokens for Granite-4.0-H-350M. That is roughly Infinityx on output cost alone. Grok 3 Mini is the reasoning model in the pair, while Granite-4.0-H-350M is not. That usually helps on harder chain-of-thought-heavy tests, but it can also mean more latency and more token spend in real use. Grok 3 Mini gives you the larger context window at 128K, compared with 32K for Granite-4.0-H-350M.

Decision framing

BenchLM keeps the benchmark table and the operator tradeoffs on the same page so a better score does not hide a materially slower, pricier, or smaller-context model.

Runtime metrics show N/A when BenchLM does not have a sourced snapshot for that exact model. The scoring rules and freshness policy are documented on the methodology page.
