01 — Verdict

Command A is our pick

Command A is the better all-round choice, scoring 24/100 against Step 2 (16K) (11). It leads on price and context window. The score weighs price 50%, inputs & features 30%, context window 20%. None of the shared benchmarks cover every model here yet, so capability is left out of this verdict.

04 — Questions

Which should you choose?

Which is better: Step 2 (16K) or Command A?

Command A is the better all-round choice, scoring 24/100 against Step 2 (16K) (11). It leads on price and context window. The score weighs price 50%, inputs & features 30%, context window 20%. None of the shared benchmarks cover every model here yet, so capability is left out of this verdict.

Which is cheaper, Step 2 (16K) or Command A?

Command A is cheaper at $2.50 input / $10.00 output per million tokens (official Cohere API price). Step 2 (16K) costs $5.21 input / $16.44 output per million tokens (official StepFun (Global) API price). At a typical mix of three input tokens to one output token, that is $4.38 per million tokens for Command A versus $8.02 for Step 2 (16K) (1.8× as much).

Which scores higher on benchmarks?

There is no independent benchmark that covers both models yet. Step 2 (16K) has not been scored yet and Command A has not been scored yet.

Which is better for coding?

There are no published SWE-bench Verified results for Step 2 (16K) and Command A yet, so there is no like-for-like coding score. Test both on a sample of your own tasks. Both support tool calling for agent workflows.

Which has the bigger context window?

Command A has the largest context window at 256,000 tokens, against 16,384 for Step 2 (16K). Maximum output per response: Step 2 (16K) up to 8,192, Command A up to 8,000 tokens.

Which can read images, PDFs, audio or video?

Step 2 (16K) accepts text; Command A accepts text. They handle the same number of input types.

Are any of these open source?

Command A publishes its weights and can be self-hosted; Step 2 (16K) is proprietary.

Which is newer?

Command A is the newest, released Mar 13, 2025. Step 2 (16K) came out Jan 1, 2025. Knowledge cutoff: Step 2 (16K) Jun 2024, Command A Jun 1, 2024.

How do you decide the winner?

Each model gets a 0–100 score on capability (50%, independent benchmark results); price (25%, blended price per million tokens (3 input : 1 output), log scale); inputs & features (15%, image, PDF, audio and video input, tool calling, structured output and reasoning); context window (10%, maximum tokens per request, log scale). Dimensions missing for any model are dropped and the remaining weights rescaled, so every model is judged on the same evidence. Specs and prices come from public model listings and the labs’ own API pages; capability scores come from independent benchmark runs. Data updated Oct 4, 2026.
