Frequently asked questions about nemotron-3-nano
- How much VRAM do I need to run nemotron-3-nano?
- At 4K context, the smallest published build of nemotron-3-nano (Q4_K_M) needs roughly 4.2 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-nano 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 4.2 GB of free RAM for the smallest build.
- How big is the nemotron-3-nano download?
- The smallest published build is 2.6 GB. There are 5 builds in total, the largest being 58.8 GB. Leave some extra free disk space beyond the download itself.
- How do I run nemotron-3-nano locally?
- Install Ollama, then run "ollama run nemotron-3-nano:4b" in a terminal. The weights download on first use and an interactive session opens.
