Which should you choose?
Which is better: Command R or Solar Pro 3?
Solar Pro 3 is the better all-round choice, scoring 55/100 against Command R (51). It leads on inputs & features. 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, Command R or Solar Pro 3?
Solar Pro 3 is cheaper at $0.25 input / $0.25 output per million tokens (official Upstage API price). Command R costs $0.15 input / $0.60 output per million tokens (official Cohere API price). At a typical mix of three input tokens to one output token, that is $0.25 per million tokens for Solar Pro 3 versus $0.263 for Command R (1.1× as much).
Which scores higher on benchmarks?
There is no independent benchmark that covers both models yet. Command R has not been scored yet and Solar Pro 3 has not been scored yet.
Which is better for coding?
There are no published SWE-bench Verified results for Command R and Solar Pro 3 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?
Solar Pro 3 has the largest context window at 131,072 tokens, against 128,000 for Command R. Maximum output per response: Command R up to 4,000, Solar Pro 3 up to 8,192 tokens.
Which can read images, PDFs, audio or video?
Command R accepts text; Solar Pro 3 accepts text. They handle the same number of input types.
Are any of these open source?
Command R publishes its weights and can be self-hosted; Solar Pro 3 is proprietary.
Which is newer?

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.
