o1-pro is our pick
o1-pro is the better all-round choice, scoring 55/100 against Sonar Deep Research (16) and Aya Vision 32B (15). 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 should you choose?
Which is better: o1-pro, Sonar Deep Research or Aya Vision 32B?
o1-pro is the better all-round choice, scoring 55/100 against Sonar Deep Research (16) and Aya Vision 32B (15). 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, o1-pro, Sonar Deep Research or Aya Vision 32B?
Sonar Deep Research is cheaper at $2.00 input / $8.00 output per million tokens (official Perplexity API price). o1-pro costs $150.00 input / $600.00 output per million tokens (official OpenAI API price). At a typical mix of three input tokens to one output token, that is $3.50 per million tokens for Sonar Deep Research versus $262.50 for o1-pro (75× as much). Aya Vision 32B has no published per-token price.
Which scores higher on benchmarks?
There is no independent benchmark that covers all three models yet. o1-pro has not been scored yet, Sonar Deep Research has not been scored yet and Aya Vision 32B has not been scored yet.
Which is better for coding?
There are no published SWE-bench Verified results for o1-pro, Sonar Deep Research and Aya Vision 32B yet, so there is no like-for-like coding score. Test both on a sample of your own tasks. Note that Sonar Deep Research and Aya Vision 32B does not support tool calling, which most coding agents need.
Which has the bigger context window?
o1-pro has the largest context window at 200,000 tokens, against 128,000 for Sonar Deep Research and 16,000 for Aya Vision 32B. Maximum output per response: o1-pro up to 100,000, Sonar Deep Research up to 32,768, Aya Vision 32B up to 4,000 tokens.
Which can read images, PDFs, audio or video?
o1-pro accepts text and images; Sonar Deep Research accepts text; Aya Vision 32B accepts text and images. o1-pro handles the widest range of inputs.
Are any of these open source?
Aya Vision 32B publishes its weights (CC-BY-NC-4.0) and can be self-hosted; o1-pro and Sonar Deep Research is proprietary.
Which is newer?
o1-pro is the newest, released Mar 19, 2025. Aya Vision 32B came out Mar 4, 2025; Sonar Deep Research came out Feb 1, 2025. Knowledge cutoff: o1-pro Sep 2023, 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.
