Estimated cost to self-host
Command A Reasoning needs about 65 GB of GPU memory at 4-bit with 32K context. The cheapest rental that fits is 8× RTX 3060 at about $346 a month.

Estimates based on median on-demand rates for Nvidia GPUs. Memory is weights plus KV cache for one request, using FP8 KV cache where supported and FP16/BF16 otherwise. No guarantee of runtime support, usable performance, or that a matching quantized build exists. How we estimate costs.
Frequently Asked Questions
What is Command A Reasoning good for?
Multi-step agent and tool-use tasks where chain-of-thought reasoning matters, in 23 languages. CC-BY-NC weights, servable on a single high-memory GPU for non-commercial use.
When is Command A Reasoning not a good fit?
Image input: it is text only. Commercial self-hosting needs a separate licence from Cohere, and it knows less of recent events than the newer Command models.
What is the cheapest way to run Command A Reasoning?
No provider we track hosts it; self-hosting on the cheapest rental that fits (8x RTX 3060, $0.48 per hour) costs about $346 a month.
Can I self-host Command A Reasoning?
Yes. The weights are CC-BY-NC licensed. At 4-bit it needs about 65 GB of GPU memory, which starts at roughly $346 a month on the cheapest rental that fits.
