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 command-a locally
- 1.Install Ollama for Windows, macOS or Linux.
- 2.Run this in a terminal:
ollama run command-a:111b - 3.The weights download on first run, then an interactive prompt opens.
Frequently asked questions about command-a
- How much VRAM do I need to run command-a?
- At 4K context, the smallest published build of command-a (Q4_K_M) needs roughly 89.8 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 command-a 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 89.8 GB of free RAM for the smallest build.
- How big is the command-a download?
- The smallest published build is 62.5 GB. There are 3 builds in total, the largest being 206.9 GB. Leave some extra free disk space beyond the download itself.
- How do I run command-a locally?
- Install Ollama, then run "ollama run command-a:111b" in a terminal. The weights download on first use and an interactive session opens.
