On Thursday, The Verge reported that OpenAI is preparing to launch GPT-5 as early as August, according to sources familiar with the company’s plans. The report comes five months after CEO Sam Altman first laid out a roadmap for the next-generation AI model that would unify the company’s various AI capabilities. OpenAI CEO Sam Altman revealed in a post on X last week that the company plans to release GPT-5 “soon.”

According to The Verge’s Tom Warren, Microsoft engineers began preparing server capacity for GPT-5 as early as late May, but testing and development challenges pushed the timeline back. During an appearance on Theo Von’s podcast this week, Altman demonstrated the model’s capabilities by having it answer a question he couldn’t. “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. In fact, we first wrote about rumors of GPT-5’s launch in March 2024, but it appears that GPT-5 did not materialize last year because the company saved the “GPT-5” name for a future release.

The Verge reports that OpenAI plans to launch what is now called GPT-5 with “mini” and “nano” versions available through its API. The main version, which will combine a conventional large language model (LLM) and a simulated reasoning (SR) model, will be available through ChatGPT and OpenAI’s API, while the nano version will reportedly only be accessible via the API.
