How to run gemma2 locally
- 1.Install Ollama for Windows, macOS or Linux.
- 2.Run this in a terminal:
ollama run gemma2:2b-text-q4_0 - 3.The weights download on first run, then an interactive prompt opens.
Frequently asked questions about gemma2
- How much VRAM do I need to run gemma2?
- At 4K context, the smallest published build of gemma2 (Q4_0) needs roughly 2.6 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 gemma2 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 2.6 GB of free RAM for the smallest build.
- How big is the gemma2 download?
- The smallest published build is 1.5 GB. There are 36 builds in total, the largest being 50.7 GB. Leave some extra free disk space beyond the download itself.
- How do I run gemma2 locally?
- Install Ollama, then run "ollama run gemma2:2b-text-q4_0" in a terminal. The weights download on first use and an interactive session opens.
