GPT-6 Sol is already in internal testing. - Early reports say it is much faster than Astra, - a bit weaker on raw quality, - and likely aimed at Plus users who need more usage room. - Possible window: OpenAI DevDay on September 29. - If Astra is the ceiling, Sol may be the everyday model people actually get to use.
