In a post on X (formerly Twitter), Altman revealed that GPT-5 is an integrated model, eliminating the need for switching between different AI versions. “It decides when it needs to think harder or not,” he explained. Notably, GPT-5 is being made available to all ChatGPT users, including those on the free tier, with advanced reasoning capabilities.
