GPT-5 had already been spotted in the wild before Altman’s appearance on This Past Weekend, fueling speculation that the next-generation GPT model was imminent. I understand OpenAI is planning to launch GPT-5 in early August, complete with mini and nano versions that will also be available through its API.

Artificial intelligence pioneer OpenAI plans to launch its GPT-5 model as early as August, The Verge reported on Thursday, citing sources familiar with the plans.

"I put it in the model, this is GPT-5, and it answered it perfectly," Altman said, saying it gave him a "weird feeling" to see the AI model answer a question that he couldn't. GPT-5 has been a highly anticipated release since the launch of GPT-4 in March 2023.
