GPT-4.1 nano· Granite-4.0-H-350M

Quick Verdict

Pick GPT-4.1 nano if you want the stronger benchmark profile. Granite-4.0-H-350M only becomes the better choice if you want the cheaper token bill.

GPT-4.1 nano is clearly ahead on the aggregate, 44 to 24. The gap is large enough that you do not need to squint at the spreadsheet to see the difference.

GPT-4.1 nano's sharpest advantage is in multilingual, where it averages 59 against 14.7. The single biggest benchmark swing on the page is MMLU, 80.1% to 35.0%.

GPT-4.1 nano is also the more expensive model on tokens at $0.10 input / $0.40 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. GPT-4.1 nano gives you the larger context window at 1M, 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.
