Sonar vs Codestral
Codestral comes out ahead, 48 to 30 on our weighted score, and it is the cheaper option too.
Codestral is our pick
Codestral is the better all-round choice, scoring 48/100 against Sonar (30). It leads on price, inputs & features 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 should you choose?
Which is better: Sonar or Codestral?
Codestral is the better all-round choice, scoring 48/100 against Sonar (30). It leads on price, inputs & features 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, Sonar or Codestral?
Codestral is cheaper at $0.30 input / $0.90 output per million tokens (official Mistral API price). Sonar costs $1.00 input / $1.00 output per million tokens (official Perplexity API price). At a typical mix of three input tokens to one output token, that is $0.45 per million tokens for Codestral versus $1.00 for Sonar (2.2× as much).
Which scores higher on benchmarks?
There is no independent benchmark that covers both models yet. Sonar has not been scored yet and Codestral has not been scored yet.
Which is better for coding?
There are no published SWE-bench Verified results for Sonar and Codestral yet, so there is no like-for-like coding score. Test both on a sample of your own tasks. Note that Sonar does not support tool calling, which most coding agents need.
Which has the bigger context window?
Codestral has the largest context window at 256,000 tokens, against 128,000 for Sonar. Maximum output per response: Sonar up to 4,096, Codestral up to 4,096 tokens.
Which can read images, PDFs, audio or video?
Sonar accepts text; Codestral accepts text. They handle the same number of input types.
Are any of these open source?
Codestral publishes its weights and can be self-hosted; Sonar is proprietary.
Which is newer?
Codestral is the newest, released May 29, 2024. Sonar came out Jan 1, 2024. Knowledge cutoff: Sonar Sep 1, 2025, Codestral Oct 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.
