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.

UPDATE 2026-09-22: a Pluralsight-based analysis (via tech-insider.org) projects no GPT-7 before the second half of 2027 based on OpenAI’s release cadence, and confirms no model called GPT-7 has appeared in any official channel. Bell remains pure speculation.
