Nemotron 3.5 Lightning

Nemotron 3.5 Lightning is a large language model from NVIDIA, part of the company's Nemotron line of models. The "Lightning" designation places it as a latency- and throughput-oriented member of the Nemotron 3.5 generation, aimed at workloads where response speed and serving cost per request matter as much as raw answer quality. Independent measurements collected by Artificial Analysis put the model's output speed at roughly 291 tokens per second with a time to first token of about 782 milliseconds. That combination — high sustained generation rate paired with a sub-second initial latency — is the model's most clearly documented characteristic in the data we track. Other specifications for this model, including context window length and supported input modalities, are not part of our verified metadata, so we do not report them here; check the provider listings in the pricing table for the exact configuration each host exposes. In practice, models positioned this way in a family are typically used for high-volume generation, chat interfaces where perceived responsiveness drives user experience, and pipeline stages that run many calls per task. Buyers comparing Nemotron 3.5 Lightning against other options generally weigh its measured throughput against heavier reasoning-focused models that trade tokens per second for depth on hard problems.
