No. Qwen Plus Character (Japanese), Sonar Deep Research and Sonar are proprietary and only available through APIs and apps.
Which is newer?
Sonar Deep Research is the newest, released Feb 1, 2025. Qwen Plus Character (Japanese) came out Jan 2024; Sonar came out Jan 1, 2024. Knowledge cutoff: Qwen Plus Character (Japanese) Apr 2024, Sonar Deep Research Jan 2025, 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.
