Frequently asked questions about hermes3
- How much VRAM do I need to run hermes3?
- At 4K context, the smallest published build of hermes3 (Q4_0) needs roughly 2.9 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 hermes3 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 2.9 GB of free RAM for the smallest build.
- How big is the hermes3 download?
- The smallest published build is 1.8 GB. There are 24 builds in total, the largest being 756.0 GB. Leave some extra free disk space beyond the download itself.
- How do I run hermes3 locally?
- Install Ollama, then run "ollama run hermes3:3b-llama3.2-q4_0" in a terminal. The weights download on first use and an interactive session opens.
