How to watch OpenAI’s ‘longer than usual’ GPT-5 reveal, as teased by a Death Star

“That’s no moon,” as Obi-Wan Kenobi once said. OpenAI CEO Sam Altman stirred intrigue with a cryptic post last night showing the Death Star from Star Wars as a hint that something big is coming.

That “something big” is undoubtedly GPT-5, OpenAI’s latest frontier model coming to ChatGPT. The company shared a less ambiguous post on X yesterday teasing the upcoming livestream.

Since then, Altman has added that OpenAI’s next livestream will be “longer than usual” with a runtime of “about an hour.”

“We have a lot to show and hope you can find the the [sic] time to watch,” Altman said in an X post.
