ChatGPT-5 will also excel at coding and answering health-related questions.

OpenAI on Thursday released GPT-5, unveiling a new version of the artificial intelligence model that fuels popular chatbot ChatGPT. The announcement comes days after the company said ChatGPT is set to reach 700 million weekly active users, up from 500 million just five months ago.
