Figures marked (est.) approximate the KV cache because this model's architecture details are not published. They are indicative rather than exact.
How to run codellama locally
- 1.Install Ollama for Windows, macOS or Linux.
- 2.Run this in a terminal:
ollama run codellama:7b-python-q4_0 - 3.The weights download on first run, then an interactive prompt opens.
Frequently asked questions about codellama
- How much VRAM do I need to run codellama?
- At 4K context, the smallest published build of codellama (Q4_0) needs roughly 5.5 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 codellama 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 5.5 GB of free RAM for the smallest build.
- How big is the codellama download?
- The smallest published build is 3.6 GB. There are 71 builds in total, the largest being 128.5 GB. Leave some extra free disk space beyond the download itself.
- How do I run codellama locally?
- Install Ollama, then run "ollama run codellama:7b-python-q4_0" in a terminal. The weights download on first use and an interactive session opens.
