GPT-6 Luna is the entry tier of OpenAI's GPT-6 series, below GPT-6 Sol. It is built for high-volume and latency-sensitive work such as chat, classification and light agent tasks, and with reasoning effort raised it can handle software engineering and computer-use tasks that used to need a Sol-class model. It shares the GPT-6 family's better factual reliability and concise style.

It accepts text, image and file (PDF) input and returns text, and supports tool calling, structured JSON output and streaming. Reasoning can be switched on when a problem needs more thought and left off when speed matters. GPT-6 Luna is commonly used for high-volume chat, classification and extraction, lightweight agents, and coding tasks at a low price. Hormouz serves it behind an OpenAI-compatible API: point your base URL at Hormouz, drop in a Hormouz key, and existing OpenAI SDK code runs without changes.

Pricing is usage-based: $0.1 per million input tokens and $0.5 per million output tokens. There is no fixed monthly fee, and you pay only for the tokens you use. Hormouz provides stable access to the model from inside Iran, with no foreign credit card or circumvention tooling required.
