With both ChatGPT and OpenAI’s API, the company plans to “release GPT-5 as a system that integrates a lot of our technology, including o3,” Altman says, adding that “we will no longer ship o3 as a standalone model.” OpenAI first teased o3 in December and launched o3-mini in January.

OpenAI chief Sam Altman has revealed that GPT-5 and GPT-4.5 are coming. GPT-5 will integrate o3 and will release in the next few months.
