The account comes from an anonymous OpenAI insider on X (post): GPT-5.6 Sol helped train GPT-6 Astra, Astra is helping train two successors codenamed Doug and Bel, and Doug is already training a model meant to outrun every human by mid-2027, with the model after Astra launching as AGI around November. Codex lead Thibault Sottiaux said Astra had pulled OpenAI’s roadmap forward six months, and one observer plotted its ECI curve just below the AI 2027 scenario. It extends the lineage that began when Sol post-trained Luna in July and turns Altman’s AGI may arrive this year into a month; the next day’s issue quantified the same loop as 3.1 agent-workdays per human workday.
Development
An insider gives the AGI successor a November ship date
The loop acquires a calendar: what had been a lab boast becomes a named lineage of models training models, with a launch month for AGI and a mid-2027 target for outrunning every human.
Claim
An OpenAI insider said the model after GPT-6 Astra launches as AGI around November, with the loop already spinning — GPT-5.6 Sol having helped train Astra, Astra helping train its successors, and one of those now training a model meant to outrun every human by mid-2027 — after Codex lead Thibault Sottiaux said Astra pulled the roadmap forward six months.
Reported metric: AGI ~November
Reporting date: (not necessarily the event date)
