Frequently asked questions about Mixtral 8x7B
- How much VRAM do I need to run Mixtral 8x7B?
- At 4K context, the smallest published build of Mixtral 8x7B (Q4_K_M) needs roughly 40.1 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 Mixtral 8x7B without a dedicated GPU?
- A supported CPU runtime can use system RAM. The smallest listed build needs an estimated 40.1 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 Mixtral 8x7B download?
- The smallest published build is 26.0 GB. Leave some extra free disk space beyond the download itself.
- How do I run Mixtral 8x7B locally?
- Install Ollama, then download a specific build with "ollama pull mixtral:8x7b". For a build that supports text generation, use ollama run with the same tag. Check the model source for its task and prompt format.
