Earlier this year, I heard that Microsoft engineers were preparing server capacity for OpenAI’s next-generation GPT-5 model, arriving as soon as late May. After some additional testing and delays, sources familiar with OpenAI’s plans tell me that GPT-5 is now expected to launch as early as next month. OpenAI CEO Sam Altman recently revealed on X that “we are releasing GPT-5 soon” and even teased some of its capabilities in a podcast appearance with Theo Von earlier this week. Altman decided to let GPT-5 take a stab at a question he didn’t understand. “I put it in the model, this is GPT-5, and it answered it perfectly,” Altman said. He described it as a “here it is moment,” adding that he “felt useless relative to the AI” because he felt like he should have been able to answer the question but GPT-5 answered it instantly. “It was a weird feeling.”
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.
I reached out to OpenAI to comment on the launch of GPT-5 in August, but the company did not respond in time for publication. Altman referred to GPT-5 as “a system that integrates a lot of our technology” earlier this year, because it will include the o3 reasoning capabilities instead of shipping those in a separate model. It’s part of OpenAI’s ongoing efforts to simplify and combine its large language models to make a more capable system that can eventually be declared artificial general intelligence, or AGI.
