O4 Mini
OpenAI's O4 Mini is a chat model capable of handling various inputs, including images, PDFs, and text, and excels at tasks such as math and coding. It is particularly strong in math-related benchmarks, with top 25% or better scores in Math Index, LiveCodeBench, AIME, and MATH-500. Notably, O4 Mini features an extended context window of 200,000 tokens, allowing it to process and understand lengthy inputs.

Frequently asked questions about O4 Mini
Answered from the entry's own fields: context, license, modalities, evidence, serving and the memory to self-host.
O4 Mini advertises a context window of 200,000 tokens, with a maximum output of 100,000 tokens in a single response. The figure is the creator's published maximum; a given host may serve less, and the gateway routes on what each host actually serves.
No. O4 Mini is a proprietary model (license: Proprietary): its weights are not distributed, and it runs only through OpenAI's own API or a host with access to it.
O4 Mini accepts Image and Text and produces Text. The capabilities card on this page lists which API features each deployment honours, such as function calling and structured output, with the source each was checked against.
O4 Mini has published results from Artificial Analysis, shown by suite in the benchmarks card above exactly as the publisher reported them. Scores are not combined across suites, and a suite that has not measured O4 Mini is shown as not available rather than estimated.
Not on the managed pool today; O4 Mini is listed for reference and comparison. Connect your own provider key or endpoint that serves it and the gateway runs it on your account, with routing decisions recorded the same way.
O4 Mini cannot be self-hosted: its weights are not distributed. It is used through an API, either OpenAI's own or the Inferbase gateway where it is served.
