How to run codeqwen locally
- 1.Install Ollama for Windows, macOS or Linux.
- 2.Run this in a terminal:
ollama run codeqwen:7b - 3.The weights download on first run, then an interactive prompt opens.
Frequently asked questions about codeqwen
- How much VRAM do I need to run codeqwen?
- At 4K context, the smallest published build of codeqwen (Q4_0) needs roughly 6.0 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 codeqwen 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 6.0 GB of free RAM for the smallest build.
- How big is the codeqwen download?
- The smallest published build is 3.9 GB. There are 9 builds in total, the largest being 13.5 GB. Leave some extra free disk space beyond the download itself.
- How do I run codeqwen locally?
- Install Ollama, then run "ollama run codeqwen:7b" in a terminal. The weights download on first use and an interactive session opens.
