Early user: GPT-6-Luna is a bad release, first OpenAI regression in over a year
peterom · x · 2026-09-24
Self-described small-model maximalist Peter says GPT-6-Luna is a bad release, feeling considerably worse than 5.6 Luna across the board.
He notes it's the first time in over a year that an OpenAI release hasn't been clearly better than what it replaced. The claim is an early user impression, not official confirmation.
