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 5.5 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?
- 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 5.5 GB of free RAM for the smallest build.
- 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 run "ollama run nous-hermes:7b" in a terminal. The weights download on first use and an interactive session opens.
