Our take
Written Aug 2, 2026o1 is a hosted-only reasoning model from OpenAI that accepts text, images and files, and can handle up to 200,000 tokens in a single request. It scores highest on coding tasks among its six measured categories, but creative writing is a clear weak point.
Pick this for coding tasks where its measured leaderboard strength stands out, or for long-document analysis that needs a very large request limit. Use it when you need multimodal reasoning over images and documents and proprietary hosting is acceptable. Skip it if you are writing creative copy, need fast output, or want price competition between providers.
The case for it
- Highest measured coding score among its six evaluated categories, with a 51.7-point gap over its next-strongest skill.
- 200,000-token request limit supports long-document analysis.
- Consistent leaderboard scores across multiple evaluation dates in late July 2026.
The case against it
- Creative writing is the lowest of its six measured categories, 27.7 points below its next-lowest score and 51.7 points below coding.
- Slow output on the only measured endpoint: 14 tokens per second on OpenAI's own service.
- Only two tracked offers with no price competition between them.

AgenticPlanning, calling tools, staying on task
Nobody we watch has scored o1 for this. We would take the rating from Arena Agent (IPS).
WritingWe do not rate this
Two boards come close and neither tests writing: Arena Creative Writing asks people which of two replies they prefer, and LiveBench Language tests whether a model understood a passage. So we show where o1 placed and give it no mark out of five.
These tests check whether a model follows instructions — a precondition for all the work above, but not a measure of how well that work is done, which is why they get no rating.
Every published score for this model6 scoresEvery figure we hold, from 6 boards, with who ran it and a link to the source — including the boards no rating above is built on.
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
From the parameter list each endpoint publishes. Streaming is omitted: nothing we hold reports it, for any model.
