Which should you choose?
Which is better: Sonar Reasoning Pro or Command R+?
Sonar Reasoning Pro is the better all-round choice, scoring 27/100 against Command R+ (22). It leads on price and 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, Sonar Reasoning Pro or Command R+?
Sonar Reasoning Pro is cheaper at $2.00 input / $8.00 output per million tokens (official Perplexity API price). Command R+ costs $2.50 input / $10.00 output per million tokens (official Cohere API price). At a typical mix of three input tokens to one output token, that is $3.50 per million tokens for Sonar Reasoning Pro versus $4.38 for Command R+ (1.3× as much).
Which scores higher on benchmarks?
There is no independent benchmark that covers both models yet. Sonar Reasoning Pro has not been scored yet and Command R+ has not been scored yet.
Which is better for coding?
There are no published SWE-bench Verified results for Sonar Reasoning Pro and Command R+ yet, so there is no like-for-like coding score. Test both on a sample of your own tasks. Note that Sonar Reasoning Pro does not support tool calling, which most coding agents need.
Which has the bigger context window?
Sonar Reasoning Pro and Command R+ share the same 128,000-token context window. Maximum output per response: Sonar Reasoning Pro up to 4,096, Command R+ up to 4,000 tokens.
Which can read images, PDFs, audio or video?
Sonar Reasoning Pro accepts text and images; Command R+ accepts text. Sonar Reasoning Pro handles the widest range of inputs.
Are any of these open source?
Command R+ publishes its weights and can be self-hosted; Sonar Reasoning Pro is proprietary.
Which is newer?
Command R+ is the newest, released Aug 30, 2024. Sonar Reasoning Pro came out Jan 1, 2024. Knowledge cutoff: Sonar Reasoning Pro Sep 1, 2025, Command R+ 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.
