Too close to call
It is close. Our weighted score puts them within 2 points (Jamba Mini 57/100, Solar Pro 3 55/100, Command R 51/100), so choose by what matters most for your work: Solar Pro 3 on price and Jamba Mini for long inputs. 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 should you choose?
Which is better: Solar Pro 3, Command R or Jamba Mini?
It is close. Our weighted score puts them within 2 points (Jamba Mini 57/100, Solar Pro 3 55/100, Command R 51/100), so choose by what matters most for your work: Solar Pro 3 on price and Jamba Mini for long inputs. 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, Solar Pro 3, Command R or Jamba Mini?
Solar Pro 3 is cheaper at $0.25 input / $0.25 output per million tokens (official Upstage API price). Jamba Mini costs $0.20 input / $0.40 output per million tokens (official AI21 Labs 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 $0.25 for Jamba Mini (1× as much) and $0.263 for Command R (1.1× as much).
Which scores higher on benchmarks?
There is no independent benchmark that covers all three models yet. Solar Pro 3 has not been scored yet, Command R has not been scored yet and Jamba Mini has not been scored yet.
Which is better for coding?
There are no published SWE-bench Verified results for Solar Pro 3, Command R and Jamba Mini yet, so there is no like-for-like coding score. Test both on a sample of your own tasks. All three support tool calling for agent workflows.
Which has the bigger context window?
Jamba Mini has the largest context window at 256,000 tokens, against 131,072 for Solar Pro 3 and 128,000 for Command R. Maximum output per response: Solar Pro 3 up to 8,192, Command R up to 4,000, Jamba Mini up to 4,096 tokens.
Which can read images, PDFs, audio or video?
Solar Pro 3 accepts text; Command R accepts text; Jamba Mini accepts text. They handle the same number of input types.
Are any of these open source?
Command R and Jamba Mini 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.
