Sam Altman, CEO of OpenAI, announced an updated roadmap for GPT-4.5 and GPT-5, focusing on simplifying product offerings and enhancing user experience. GPT-4.5, known as Orion, will be the last model without a chain-of-thought feature. The goal is to create a unified intelligence system that integrates o-series and GPT-series models. GPT-5 will merge various OpenAI technologies and will replace the standalone o3 model. Changes to ChatGPT will allow free users unlimited access to GPT-5, while Plus and Pro subscribers can access enhanced features.
