Pick Claude Sonnet 4.5 if you want the stronger benchmark profile. Granite-4.0-350M only becomes the better choice if you want the cheaper token bill.
Claude Sonnet 4.5 is clearly ahead on the aggregate, 69 to 27. The gap is large enough that you do not need to squint at the spreadsheet to see the difference.
Claude Sonnet 4.5's sharpest advantage is in multilingual, where it averages 88.4 against 16.2. The single biggest benchmark swing on the page is MGSM, 91% to 16.2%.
Claude Sonnet 4.5 is also the more expensive model on tokens at $3.00 input / $15.00 output per 1M tokens, versus $0.00 input / $0.00 output per 1M tokens for Granite-4.0-350M. That is roughly Infinityx on output cost alone. Claude Sonnet 4.5 gives you the larger context window at 200K, compared with 32K for Granite-4.0-350M.
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.
