Too close to call
It is close. Our weighted score puts them within a point (o1-pro 55/100, o3-pro 55/100, Aya Vision 32B 15/100), so choose by what matters most for your work: o3-pro on price. 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, o3-pro or Aya Vision 32B?
It is close. Our weighted score puts them within a point (o1-pro 55/100, o3-pro 55/100, Aya Vision 32B 15/100), so choose by what matters most for your work: o3-pro on price. 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, o3-pro or Aya Vision 32B?
o3-pro is cheaper at $20.00 input / $80.00 output per million tokens (official OpenAI 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 $35.00 per million tokens for o3-pro versus $262.50 for o1-pro (7.5× 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, o3-pro has an ECI of 147.4 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, o3-pro 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 Aya Vision 32B does not support tool calling, which most coding agents need.
Which has the bigger context window?
o1-pro and o3-pro have the largest context windows (200,000 and 200,000 tokens), against 16,000 for Aya Vision 32B. Maximum output per response: o1-pro up to 100,000, o3-pro up to 100,000, Aya Vision 32B up to 4,000 tokens.
Which can read images, PDFs, audio or video?
o1-pro accepts text and images; o3-pro accepts text and images; Aya Vision 32B accepts text and images. They handle the same number of input types.
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 o3-pro is proprietary.
Which is newer?
o3-pro is the newest, released Jun 10, 2025. o1-pro came out Mar 19, 2025; Aya Vision 32B came out Mar 4, 2025. Knowledge cutoff: o1-pro Sep 2023, o3-pro May 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.
