GPT-OSS 20B· Sarvam 105B

Quick Verdict

Pick Sarvam 105B if you want the stronger benchmark profile. GPT-OSS 20B only becomes the better choice if you would rather avoid the extra latency and token burn of a reasoning model.

Sarvam 105B is clearly ahead on the aggregate, 60 to 36. The gap is large enough that you do not need to squint at the spreadsheet to see the difference.

Sarvam 105B's sharpest advantage is in mathematics, where it averages 92.3 against 38.1. The single biggest benchmark swing on the page is AIME 2025, 32% to 88.3%.

Sarvam 105B is the reasoning model in the pair, while GPT-OSS 20B 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.

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.
