01 — Verdict

Vision Medium is our pick

Vision Medium is the better all-round choice, scoring 84/100 against Codestral (29) and Sonar (10). It leads on inputs & features and context window. The score weighs inputs & features 60%, context window 40%. None of the shared benchmarks cover every model here yet, so capability is left out of this verdict.

04 — Questions

Which should you choose?

Which is better: Codestral, Sonar or Vision Medium?

Vision Medium is the better all-round choice, scoring 84/100 against Codestral (29) and Sonar (10). It leads on inputs & features and context window. The score weighs inputs & features 60%, context window 40%. None of the shared benchmarks cover every model here yet, so capability is left out of this verdict.

Which is cheaper, Codestral, Sonar or Vision Medium?

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). Vision Medium has no published per-token price.

Which scores higher on benchmarks?

There is no independent benchmark that covers all three models yet. Codestral has not been scored yet, Sonar has not been scored yet and Vision Medium has not been scored yet.

Which is better for coding?

There are no published SWE-bench Verified results for Codestral, Sonar and Vision Medium 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?

Vision Medium has the largest context window at 1,000,000 tokens, against 256,000 for Codestral and 128,000 for Sonar. Maximum output per response: Codestral up to 4,096, Sonar up to 4,096, Vision Medium up to 65,536 tokens.

Which can read images, PDFs, audio or video?

Codestral accepts text; Sonar accepts text; Vision Medium accepts text, images, PDFs, audio and video. Vision Medium handles the widest range of inputs.

Are any of these open source?

Codestral publishes its weights and can be self-hosted; Sonar and Vision Medium is proprietary.

Which is newer?

Codestral is the newest, released May 29, 2024. Vision Medium came out May 15, 2024; Sonar came out Jan 1, 2024. Knowledge cutoff: Codestral Oct 2024, Sonar 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.
