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 2026The 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.
