Sonar accepts text; Sonar Reasoning Pro accepts text and images; Qwen Plus Character (Japanese) accepts text. Sonar Reasoning Pro handles the widest range of inputs.
Are any of these open source?
No. Sonar, Sonar Reasoning Pro and Qwen Plus Character (Japanese) are proprietary and only available through APIs and apps.
Which is newer?
Sonar is the newest, released Jan 1, 2024. Sonar Reasoning Pro came out Jan 1, 2024; Qwen Plus Character (Japanese) came out Jan 2024. Knowledge cutoff: Sonar Sep 1, 2025, Sonar Reasoning Pro Sep 1, 2025, Qwen Plus Character (Japanese) Apr 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.
