Our take
Written Sep 1, 2026o3 Pro is a hosted-only reasoning model from OpenAI that accepts text, images and files across a 200,000-token request limit. It is positioned for complex document analysis, though its premium cost and lack of measured quality data make it a speculative pick.
Choose this for long-document analysis with mixed media where the 200,000-token limit is essential, or where you need OpenAI's direct hosting at 10 tokens per second. Skip it if you need fast production throughput, verified quality scores, or anything close to mid-market pricing.
The case for it
- 200,000-token request limit among the largest we track for a text-plus-image-plus-file model.
- Accepts mixed media inputs — text, images and files together in one request.
The case against it
- Premium cost with no measured quality advantage: zero benchmark scores in our data and no independent verification available.
- Very low disclosed throughput at 10 tokens per second on OpenAI direct, slow for production use.
- Only two tracked offers, both at the same tier, with no price competition.
How good is it?
We hold no score for this model.
So there is no figure here for everyday use, coding, agent work or writing. That is a gap in our data, not a low score.
