It costs $2.50 per million input tokens and $10 per million output tokens.
It supports tool calling and structured JSON output, and its weights are open, so you can host it yourself.
6 providers serve it, including Vercel AI Gateway, Eden AI and Kilo Gateway.
On the Artificial Analysis Intelligence Index it scores 7, which places it at number 41 among the 43 models I track with independent scores.

Command A pricing
USD, as listed on Oct 15, 2026. Most bills are input heavy, so the cached input rate matters as much as the headline price.

Command A providers
6 providers serve it, including Vercel AI Gateway, Eden AI and Kilo Gateway. Each host sets its own price and limits, so the cheapest one is not always the one with the longest context.

Command A questions
How much does the Command A API cost?
$2.50 per million input tokens and $10 per million output tokens. The estimator on this page turns that into a monthly bill for your own workload.
What is the context window of Command A?
256,000 tokens of input, and it can write up to 8,192 tokens in one reply. As a rough guide, a million tokens is around 750,000 English words.
Which providers serve Command A?
6 providers serve it, including Vercel AI Gateway, Eden AI and Kilo Gateway. Prices differ by host, so the Providers table on this page lists each one with its input and output price.
Does Command A support tool calling?
Yes. It accepts tool definitions and can return JSON that matches a schema, which is what an agent needs to call your APIs.
Is Command A open source?
Its weights are published, so you can run it on your own hardware or a cloud of your choice. Read the license before commercial use.
When was Command A released?
Mar 13, 2025, with training data up to Aug 2024.
How good is Command A compared with other models?
It scores 7 on the Artificial Analysis Intelligence Index. Benchmarks are a shortlist, not a verdict: test the top two or three candidates on your own tasks before you commit.
Catalog data from models.dev (MIT licensed), refreshed daily, last on Oct 15, 2026. Independent scores from my hand checked rankings, sources linked above. The summary is written from these facts.
Building on Command A?
I test your real tasks on it and the two closest alternatives, then ship the agent on whichever wins on cost and accuracy.
