Frequently asked questions about qwen2.5-coder
- How much VRAM do I need to run qwen2.5-coder?
- At 4K context, the smallest published build of qwen2.5-coder (Q4_0) needs roughly 1.0 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 qwen2.5-coder 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 1.0 GB of free RAM for the smallest build.
- How big is the qwen2.5-coder download?
- The smallest published build is 0.3 GB. There are 72 builds in total, the largest being 61.0 GB. Leave some extra free disk space beyond the download itself.
- How do I run qwen2.5-coder locally?
- Install Ollama, then run "ollama run qwen2.5-coder:0.5b-base-q4_0" in a terminal. The weights download on first use and an interactive session opens.
