Frequently asked questions about nemotron-3.5-lightning
- How much VRAM do I need to run nemotron-3.5-lightning?
- At 4K context, the smallest published build of nemotron-3.5-lightning (Q4_K_M) needs roughly 34.3 GB of GPU memory once weights, KV cache, compute buffers and runtime overhead are counted. Bigger quantizations and longer context windows need more. It can also run partly or entirely on the CPU using system RAM, more slowly.
- Can I run nemotron-3.5-lightning without a dedicated GPU?
- Yes, but slowly. Without a GPU the model runs on the CPU using system RAM, which usually means a few tokens per second rather than dozens. You would need at least 34.3 GB of free RAM for the smallest build.
- How big is the nemotron-3.5-lightning download?
- The smallest published build is 23.7 GB. There are 2 builds in total, the largest being 32.6 GB. Leave some extra free disk space beyond the download itself.
- How do I run nemotron-3.5-lightning locally?
- Install Ollama, then run "ollama run nemotron-3.5-lightning:30b" in a terminal. The weights download on first use and an interactive session opens.
