Too close to call
It is close. Our weighted score puts them within 2 points (Command R+ 22/100, Sonar Pro 20/100), so choose by what matters most for your work: Command R+ on price and Sonar Pro 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: Command R+ or Sonar Pro?
It is close. Our weighted score puts them within 2 points (Command R+ 22/100, Sonar Pro 20/100), so choose by what matters most for your work: Command R+ on price and Sonar Pro 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, Command R+ or Sonar Pro?
Command R+ is cheaper at $2.50 input / $10.00 output per million tokens (official Cohere API price). Sonar Pro costs $3.00 input / $15.00 output per million tokens (official Perplexity API price). At a typical mix of three input tokens to one output token, that is $4.38 per million tokens for Command R+ versus $6.00 for Sonar Pro (1.4× 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 Sonar Pro has not been scored yet.
Which is better for coding?
There are no published SWE-bench Verified results for Command R+ and Sonar Pro yet, so there is no like-for-like coding score. Test both on a sample of your own tasks. Note that Sonar Pro does not support tool calling, which most coding agents need.
Which has the bigger context window?
Sonar Pro has the largest context window at 200,000 tokens, against 128,000 for Command R+. Maximum output per response: Command R+ up to 4,000, Sonar Pro up to 8,192 tokens.
Which can read images, PDFs, audio or video?
Command R+ accepts text; Sonar Pro accepts text and images. Sonar Pro handles the widest range of inputs.
Are any of these open source?
Command R+ publishes its weights and can be self-hosted; Sonar Pro is proprietary.
Which is newer?
Command R+ is the newest, released Aug 30, 2024. Sonar Pro came out Jan 1, 2024. Knowledge cutoff: Command R+ Jun 1, 2024, Sonar Pro Sep 1, 2025.
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.
