Too close to call
It is close. Our weighted score puts them within a point (Sonar Deep Research 16/100, Aya Vision 8B 15/100), so choose by what matters most for your work: Sonar Deep Research on price and Sonar Deep Research for long inputs. 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.

Aya Vision 8B publishes its weights (CC-BY-NC-4.0) and can be self-hosted; Sonar Deep Research is proprietary.
Which is newer?
Aya Vision 8B is the newest, released Mar 4, 2025. Sonar Deep Research came out Feb 1, 2025. Knowledge cutoff: Sonar Deep Research Jan 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.
