Leak: OpenAI models being upgraded to gpt-6-sol and gpt-6-luna internally

FlolightC · x · 2026-09-23

Developer FlolightC reports internal model names being updated: gpt-5.6-terra becomes gpt-6-sol (medium), gpt-5.6-luna becomes gpt-6-luna (medium or high, TBD), and even a broken gpt-5.4-mini was replaced with gpt-6-luna. He also weighs adding "Astra" somewhere. If accurate, it suggests OpenAI's next-gen gpt-6 family is already in internal deployment with multiple variants. Unverified.
