OpenAI unveiled GPT‑5 on Thursday, calling it its smartest, fastest and most useful model yet, according to CNBC. CEO Sam Altman described the new version of ChatGPT as a Ph.D.-level expert, capable of generating more accurate responses, stronger reasoning, and improved articulation. The company said GPT‑5 reduces factual errors by 45% compared to GPT‑4o and enhances performance in coding, health-related questions, and writing. The update also includes fewer hallucinations, toned-down flattery, and limited emoji use. OpenAI will offer ChatGPT-5 free globally as part of its mission to make AI accessible and beneficial to all humanity, according to product head Nick Turley. ChatGPT now serves over 700 million weekly users.
