OpenAI Launches GPT-5 Upgrade with New ChatGPT Personalities, Wider Access

OpenAI has officially launched GPT-5, a significant upgrade to its ChatGPT model, now available to all users including those on the free tier. GPT-5 is faster, more accurate, and capable of advanced tasks such as coding entire websites and providing improved health-related responses, with a notable reduction in hallucinations and errors. The update introduces new customizable personalities—Default, Cynic, Robot, Listener, and Nerd—that allow users to tailor ChatGPT's tone and interaction style, enhancing user experience. Additionally, a refreshed ChatGPT user interface simplifies interaction with a new prompt composer and expanded voice mode features accessible by all users. CEO Sam Altman described GPT-5 as a major step toward artificial general intelligence, likening its conversational ability to that of a PhD-level expert, marking a leap from the previous GPT-4’s college student level. OpenAI also released open-source LLMs alongside GPT-5 and improved integrations with productivity apps, signaling a broad push to enhance functionality and customization.
