Our take
Written Sep 30, 2026o1 is a hosted-only model from OpenAI: we list no download for it, so using it means choosing a host, and both hosts we list charge the same rate. Its measured quality sits mid-field on every board we hold, so treat it as a general-purpose chat model rather than a category leader.
Use it for general chat, drafting and document work where you want a hosted model that takes images and files and can hold a long document in one request. It is also the pick when you want a single vendor relationship, since OpenAI hosts it directly alongside OpenRouter at the same rate. Skip it if you need a model you can download and run yourself, or if you need top-of-board measured quality in coding, maths or creative writing.
The case for it
- A long report or a stack of documents can sit beside the question without being split up first, though reliable recall across all of it is unverified in our data.
- Images and files go into the same request as the text, so a screenshot or a document does not have to be described in words first.
- OpenAI hosts it directly alongside OpenRouter, so you are not dependent on a third party for access.
The case against it
- Mid-field on every board we hold: 94th of 168 on Arena Text (overall) as of 25 Sep 2026 and 108th of 168 on Arena Coding as of 25 Sep 2026, both preference-based boards that record which answer people preferred rather than whether it was correct.
- We list no download for it, so using it means choosing a host, and both listed hosts charge the same rate.
- Parameter count is not published, so how large the model is cannot be judged from our data.

OpenRouterAcross the 2 listings we hold: 1 says it does not train on prompts, 0 say they do and 1 does not say. 0 appear in the zero-retention registry we check; the rest are unknown to us.
What each host's API supports
From the parameter list each endpoint publishes. Streaming is omitted: nothing we hold reports it, for any model.
