Frequently asked questions about GPT-4-0613
Answered from the entry's own fields: context, license, modalities, evidence, serving and the memory to self-host.
GPT-4-0613 advertises a context window of 8,192 tokens, with a maximum output of 4,096 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-4-0613 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-4-0613 accepts 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.
No published benchmark result for GPT-4-0613 is in the catalog yet, so the model is shown as unmeasured. It is not ranked or estimated; the router treats it as unknown for every task until a suite measures it.
Not on the managed pool today; GPT-4-0613 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-4-0613 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.
