Frequently asked questions about mistral-openorca
- How much VRAM do I need to run mistral-openorca?
- At 4K context, the smallest published build of mistral-openorca (Q4_0) needs roughly 5.9 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 mistral-openorca 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 5.9 GB of free RAM for the smallest build.
- How big is the mistral-openorca download?
- The smallest published build is 3.8 GB. There are 6 builds in total, the largest being 13.5 GB. Leave some extra free disk space beyond the download itself.
- How do I run mistral-openorca locally?
- Install Ollama, then run "ollama run mistral-openorca:7b" in a terminal. The weights download on first use and an interactive session opens.
