Frequently asked questions about GPT-5.4-NANO
Answered from the entry's own fields: context, license, modalities, evidence, serving and the memory to self-host.
GPT-5.4-NANO advertises a context window of 272,000 tokens, with a maximum output of 128,000 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. GPT-5.4-NANO 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.
GPT-5.4-NANO 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.
GPT-5.4-NANO 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 GPT-5.4-NANO is shown as not available rather than estimated.
Not on the managed pool today; GPT-5.4-NANO 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.
GPT-5.4-NANO 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.
