Chatter points to a Tuesday (Sept 22) release of GPT-6 Sol, a faster, cheaper everyday tier below GPT-6 Astra. The fuel: Sam Altman said his big launch slipped from last week to this week, and Tibo Sottiaux teased DevDay-level launches. But earlier rumored dates (Sept 17) came and went with nothing, and OpenAI's catalog shows no gpt-6-sol — only gpt-6-astra and gpt-6-astra-pro. Rumored positioning mirrors the GPT-5.6 Sol playbook: cheaper with higher usage limits.
