How to run nemotron-3.5-lightning locally
- 1.Install Ollama for Windows, macOS or Linux.
- 2.Download this exact build in a terminal:
ollama pull nemotron-3.5-lightning:30b - 3.Check the source for the build's task. For text generation, run
ollama run nemotron-3.5-lightning:30b. Base/text builds may need a prompt template; an instruct build is usually the appropriate starting point for a conversation.
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 29.3 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?
- A supported CPU runtime can use system RAM. The smallest listed build needs an estimated 29.3 GB at 4K context, plus headroom for your operating system. Check the build's runtime requirements. We have not measured its speed on your CPU.
- 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 download a specific build with "ollama pull nemotron-3.5-lightning:30b". For a build that supports text generation, use ollama run with the same tag. Check the model source for its task and prompt format.
