OpenAI launches GPT-5 free to all ChatGPT users
On Thursday, OpenAI announced GPT-5 and three variants-GPT-5 Pro, GPT-5 mini, and GPT-5 nano-what the company calls its "best AI system yet," with availability for some of the models across all ChatGPT tiers, including free users. The new model family arrives with claims of reduced confabulations, improved coding capabilities, and a new approach to handling sensitive requests that OpenAI calls "safe completions."
It's also the first time OpenAI has given free users access to a simulated reasoning AI model, which breaks problems down into multiple steps using a technique that tends to improve answer accuracy for logical or analytical questions.
GPT-5 represents OpenAI's latest attempt to unify its various AI capabilities into a single system. The company says the GPT-5 family acts as a "unified system" with a smart, efficient model that answers most questions, a deeper reasoning model called "GPT-5 thinking" for harder problems, and a real-time router that decides which approach to use based on conversation type, complexity, tool needs, and user intent. Like GPT-4o, GPT-5 is a multimodal system that can interact via images, voice, and text.
