Frequently asked questions about llama3-chatqa
- How much VRAM do I need to run llama3-chatqa?
- At 4K context, the smallest published build of llama3-chatqa (Q4_0) needs roughly 6.6 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 llama3-chatqa 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 6.6 GB of free RAM for the smallest build.
- How big is the llama3-chatqa download?
- The smallest published build is 4.3 GB. There are 12 builds in total, the largest being 131.4 GB. Leave some extra free disk space beyond the download itself.
- How do I run llama3-chatqa locally?
- Install Ollama, then run "ollama run llama3-chatqa:8b" in a terminal. The weights download on first use and an interactive session opens.
