OpenAI offers free, unlimited GPT-5 access with model simplification.

OpenAI, under the direction of CEO Sam Altman, will grant free ChatGPT users unlimited access to GPT-5, enhancing user interaction by integrating its o3 reasoning model. Altman outlined the initiative to simplify user interfaces and eliminate the complexity of the current model selection, transitioning towards a unified intelligence system.
With GPT-4.5 set to be OpenAI's final non-chain-thought model, future developments will focus on solving problems through intermediate steps. The company's ultimate goal targets the unification of o-series and GPT-series models, potentially transforming them into a comprehensive system that determines optimal problem-solving times.
Anticipating GPT-5, OpenAI intends to incorporate a wide array of its technological advancements, including the o3 model and Deep Research feature. Altman expressed the timeline for GPT-4.5 and GPT-5 as speculative, expecting releases in weeks or months, while maintaining usability for a broad range of tasks and offering differentiated intelligence levels for Plus and Pro users.
