Nemotron 3.5 Lightning completes tasks 5.36x faster than the most intelligent model that runs on the DGX Spark (Step 3.7 Flash) while retaining 78% Intelligence. Why is it 5.36x faster? Despite being a much smaller model, Lightning uses about the same number of output tokens per task as Flash (on average ~2% more). However, it runs much faster per token on decode on DGX Spark, accounting for the 5.36x overall speedup.

Terms in this piece · Glossary
- token — The chunk of text a model reads and writes in — roughly three-quarters of a word — and the unit AI usage is billed in.
Why it matters
Quantifies what a smaller model actually costs you in capability when you trade down for speed on fixed local hardware.
