GPT-6 Luna benchmarks
GPT-6 Luna is a proprietary model from OpenAI, released 22 Sep 2026. It ranks 34th of 51 on our overall leaderboard and 4th of 50 for value, though some of its results are not yet published. At A$0.28 per million tokens (blended), it costs about 13× cheaper than the median model we track. It writes about 167 tokens a second, and answers start after 45 s on average, thinking included. It can be called from Microsoft Azure in Australia East, but only through global routing, so requests may be processed outside Australia.
