Nemotron 3.5 Lightning

Nemotron 3.5 Lightning is a NVIDIA open-weights reasoning model, released 11 Aug 2026. Its best configuration ranks #457 of 785 on the BenchLeader Index at 47.4 ±6.3, in the lower half. The ± is the point: 378 other configurations score within that range, so they and this one cannot be told apart on quality alone — price and speed are what separate them. It scores highest in long context (55) and lowest in agents & tools (37). At $0.095 per million tokens blended it is among the cheapest fifth of ranked models. Output speed of 288 tokens per second puts it in the fastest quarter, with a first answer in 7.6 s. Last measured 11 Aug 2026.

How its index has moved

19 Sept 2026 to 23 Oct 2026
414855

The index is recomputed from scratch every day, so a line moves when a new benchmark result lands, when a publisher revises a score, or when the models it is normalised against change. Early movement usually means the score is still settling.
