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, Vision Large or Sonar Reasoning Pro?
Sonar Reasoning Pro is cheaper at $2.00 input / $8.00 output per million tokens (official Perplexity 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 . Vision Large has no published per-token price.
Which scores higher on benchmarks?
There is no independent benchmark that covers both models yet. Vision Large has not been scored yet and Sonar Reasoning Pro has not been scored yet.
Which is better for coding?
There are no published SWE-bench Verified results for Vision Large and Sonar Reasoning Pro 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?
Vision Large has the largest context window at 1,000,000 tokens, against 128,000 for Sonar Reasoning Pro. Maximum output per response: Vision Large up to 65,536, Sonar Reasoning Pro up to 4,096 tokens.
Which can read images, PDFs, audio or video?
Vision Large accepts text, images, PDFs, audio and video; Sonar Reasoning Pro accepts text and images. Vision Large handles the widest range of inputs.
Are any of these open source?
No. Vision Large and Sonar Reasoning Pro are proprietary and only available through APIs and apps.
Which is newer?
Vision Large is the newest, released May 15, 2024. Sonar Reasoning Pro came out Jan 1, 2024. Knowledge cutoff: Sonar Reasoning 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.
