Can I run nous-hermes?
General use models based on Llama and Llama 2 from Nous Research.
Parameter counts and memory belong to each build below. A family can contain several sizes and tasks; fitting in memory is not a quality ranking.

Showing the 8 smallest non-alias builds. Choose any build and change the context. A context above the build's documented maximum is a hypothetical calculation, not a supported setting.
How to run nous-hermes locally
- 1.Install Ollama for Windows, macOS or Linux.
- 2.Download this exact build in a terminal:
ollama pull nous-hermes:7b - 3.Check the source for the build's task. For text generation, run
ollama run nous-hermes:7b. Base/text builds may need a prompt template; an instruct build is usually the appropriate starting point for a conversation.
Frequently asked questions about nous-hermes
- How much VRAM do I need to run nous-hermes?
- At 4K context, the smallest published build of nous-hermes (Q4_0) needs roughly 6.2 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 nous-hermes without a dedicated GPU?
- A supported CPU runtime can use system RAM. The smallest listed build needs an estimated 6.2 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 nous-hermes download?
- The smallest published build is 3.6 GB. There are 23 builds in total, the largest being 128.5 GB. Leave some extra free disk space beyond the download itself.
- How do I run nous-hermes locally?
- Install Ollama, then download a specific build with "ollama pull nous-hermes:7b". For a build that supports text generation, use ollama run with the same tag. Check the model source for its task and prompt format.
