Can I run command-a?
111 billion parameter model optimized for demanding enterprises that require fast, secure, and high-quality AI
Parameter counts and memory belong to each build below. A family can contain several sizes and tasks; fitting in memory is not a quality ranking.
Calculate memory for a build and contextcommand-a system requirements
Memory needed at 4K context, counting model weights, KV cache, compute buffers and runtime overhead. Download sizes come from the official Ollama registry.

Showing the 3 smallest non-alias builds. Choose any build and change the context. A context above the build's documented maximum is a hypothetical calculation, not a supported setting.
How to run command-a locally
- 1.Install Ollama for Windows, macOS or Linux.
- 2.Download this exact build in a terminal:
ollama pull command-a:111b - 3.Check the source for the build's task. For text generation, run
ollama run command-a:111b. Base/text builds may need a prompt template; an instruct build is usually the appropriate starting point for a conversation.
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 68.9 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 command-a without a dedicated GPU?
- A supported CPU runtime can use system RAM. The smallest listed build needs an estimated 68.9 GB at 4K context, plus headroom for your operating system. Check the build's runtime requirements. We have not measured its speed on your CPU.
- 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 download a specific build with "ollama pull command-a:111b". For a build that supports text generation, use ollama run with the same tag. Check the model source for its task and prompt format.
