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.

Despite launching its ambitious ChatGPT Agent just last week, in typical OpenAI fashion, there are rumblings of an even bigger release on the near horizon: GPT-5.

A person who tested GPT-5 told The Information it outperformed Claude Sonnet 4 in side-by-side comparisons. That’s just one data point and Claude Opus 4 is still considered Anthropic’s most advanced model, but it signals OpenAI is serious about reclaiming ground in this space.
