About
GPT Luna Latest is an OpenAI model identifier that always redirects to the latest model in the GPT Luna family. It accepts file, image, and text inputs and returns text, with support for reasoning, tools, and vision. The model lists a 1,050,000-token context window and a maximum output of 128,000 tokens. Released on 2026-09-11, it uses the ~openai family and is available through the listed OpenRouter page. Pricing is USD 0.10 per 1M input tokens and USD 0.50 per 1M output tokens. Because the identifier redirects to the family’s latest model, integrations using it point to that changing target rather than a separately named fixed model. Teams can apply it to multimodal text-generation workflows involving documents, images, or plain text.
Who it is for
It suits teams that want access to the latest model in the GPT Luna family through one identifier. Multimodal inputs, reasoning, tools, and vision support fit varied application workflows.
