GPT-6 Release Date prediction

OpenAI has just over three weeks left before the deadline, and there is no sign it is close to shipping GPT-6. The company's recent public work has centered on GPT-5.6 point releases, named Luna and Sol, not a generational jump. There is no model card, no API route, and no public preview for a GPT-6-branded product. More tellingly, OpenAI's next major internal effort, code-named Astra, was reportedly slowed down this past week. An internal security review flagged concerning capability jumps in coding and cybersecurity. That is the opposite of a company racing to ship a flagship successor within a month. Big model launches also typically come with weeks or months of staged rollout, developer previews, and safety evaluations. None of that has surfaced. Historically, major version jumps such as GPT-3 to GPT-4 or GPT-4 to GPT-5 involved long, telegraphed windows with leaks, benchmark teasers, and executive hints well in advance. None of that noise exists here for GPT-6. The company's own behavior points to continued incremental releases under the GPT-5.x banner for now. A surprise announcement tied to a developer event or earnings call could change this quickly, but nothing in the current pipeline suggests that is imminent. Watch for any change in messaging around Astra: if it is rebranded or upgraded to GPT-6 status abruptly, that would change the picture.
