GPT-6 Luna

The fast, affordable GPT-6 — sub-agents and high-volume work.

GPT-6 Luna is the fast, low-cost tier of the GPT-6 line: a sharper coder than GPT-5.6 Luna at half its vendor price, with reasoning effort up to max. Built for sub-agents, focused repeatable tasks, high-volume pipelines and latency-sensitive work where Sol would be overkill.
