According to PANews, OpenAI CEO Sam Altman has revealed the roadmap for GPT-4.5 and GPT-5. GPT-4.5, internally codenamed Orion, is set to be OpenAI's final non-'Chain-of-Thought' model and is expected to be released in the coming weeks or months. Following this, OpenAI plans to integrate the o series with the GPT series models to enhance their ability to use tools intelligently and adapt to various task requirements.
GPT-5 will incorporate the o3 model and include features such as voice, Canvas, search, and deep research capabilities. ChatGPT's free users will have unlimited access to the standard intelligence version of GPT-5, while Plus and Pro users will be able to access higher intelligence levels of GPT-5.
