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. Also new: edgen.tech reports developers this week found API requests quietly rerouted to a model that does not officially exist — 'gpt-6-sol' — described by leaked testers as near-flagship on coding at a fraction of Astra's price, with DevDay (Sept 29) floated as the venue where pricing gets confirmed. OpenAI still shows no gpt-6-sol in its catalog; Tuesday (Sept 22) remains the rumor's next date to watch.

AI creator Matthew Berman's latest upload is a sit-down with OpenAI's Tibo Sottiaux — the face behind the ChatGPT usage-reset announcements — on how to read the next wave of AI developments. Second Berman video on Tibo this month after his earlier Pragmatic Engineer coverage; Tibo's posts are also central to the GPT-6 Sol rumor cycle.

Unconfirmed reports and speculation suggest OpenAI's next generation after Astra may be GPT-7 ("Bell"), aimed at improving multimodal capabilities and cost-efficiency. No official confirmation from OpenAI.

In an interview with Fortune editor-in-chief Alyson Shontell, Altman ruled out a 2026 IPO ('We've got a lot of stuff to do'), tying the delay to AI safety after the OpenAI–Hugging Face agent incident. He backed Dario Amodei's call to slow frontier development and hinted a cross-industry safety pact 'will happen.'

OpenAI's head of Core Products & Platform — the face behind the usage-reset announcements — talks through how Codex was built and iterated: why the CLI is Rust and open source, how the harness and models evolved, why Codex supports multiple providers, and the ChatGPT + Codex merger.

OpenAI's new flagship model, succeeding GPT-5.6 Sol. State-of-the-art on computer use, browsing, software engineering and science per OpenAI; rolls out to ChatGPT Plus, Pro, Business and Enterprise tiers in waves, plus API access.
