Frequently asked questions about GPT-6 Luna
Answered from the entry's own fields: context, license, modalities, evidence, serving and the memory to self-host.
GPT-6 Luna advertises a context window of 1,050,000 tokens, with a maximum output of 128,000 tokens in a single response. The figure is the creator's published maximum; a given provider may serve less, and the gateway routes on what each provider actually serves.
No. GPT-6 Luna is a proprietary model (license: Proprietary): its weights are not distributed, and it runs only through OpenAI's own API or a provider licensed to serve it.
GPT-6 Luna accepts Text and Image 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-6 Luna 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-6 Luna is shown as not available rather than estimated.
Not on the managed pool today; GPT-6 Luna 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-6 Luna 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.
