GPT-6 Luna
OpenAI's September 22, 2026 GPT-6 model for cost-sensitive, high-volume workloads, and the cheapest frontier-lab model at $0.10 input and $0.50 output per million tokens. Supports text and image input, text output and adjustable reasoning effort from none to max (default medium), with a 1.05M-token context window and up to 128K output. Cached input is $0.01 and cache writes $0.125, with the same above-272K long-context surcharge as GPT-6 Sol. OpenAI reports DeepSWE v1.1 66.6% at $0.22 per task, Agents' Last Exam 50.9% and FrontierCode 1.1 42.4%; Artificial Analysis has not yet published an Intelligence Index for it.
