Our take
Written Aug 2, 2026o3 Deep Research is a hosted-only reasoning model from OpenAI that accepts documents, images and files to produce long-form text analysis. It handles up to 200,000 tokens in a single request, but carries a premium price with no measured quality data in our catalogue.
Pick this when you need to analyse very long documents alongside images and files in one prompt, and the budget allows a premium tier. Skip it if you need verified quality scores, price competition between providers, or a lower-cost option.
The case for it
- Extremely large request limit for document-heavy research: up to 200,000 tokens.
- Accepts mixed inputs — text, images and files — in a single prompt for complex research workflows.
The case against it
- Premium pricing with no measured quality evidence in our data: quality is unverified in our catalogue.
- No price competition between its two offers: identical pricing on both tracked hosts means no cheaper option available.
How good is it?
We hold no score for this model.
We look for every model we track on every board we watch, and none of them has turned up o3 Deep Research — so there is no intelligence, coding, agentic or writing score to show you, not a low one, none.
Or rent it from someone else
Why this differs from the header. The strip above quotes OpenAI's own list price. This is the cheapest live offer at the widest standard context we hold, whoever is serving it — a reseller undercutting a lab is ordinary commerce, not an error.

What each host's API supports
