OpenAI released GPT-5 on August 7, 2025.. GPT-5 replaces earlier models like GPT-4, GPT-4.5.
It is a unified AI system that chooses when to respond fast or think deeper. GPT-5 handles tasks across coding, math, writing, health, vision, and more. The model shows much fewer factual errors than previous versions. It is the best coding model OpenAI has built.
GPT-5 is available to everyone. Free users can access base GPT-5. Paid users get higher usage and more features. There are smaller versions—GPT-5 mini and GPT-5 nano—that are cheaper and faster. GPT-5 Pro is for complex tasks and provides deep reasoning.
Benchmarks show GPT-5 is strong at math, coding, health, and multimodal tasks. OpenAI CEO called GPT-5 “expert-level intelligence” and a step toward generally intelligent AI.
Some early testers and news reports noted GPT-5 is smarter, faster, and more accurate. A systematic study shows GPT-5 outperforms GPT-4 in areas like lesson planning, clinical reasoning, and ethical reflection. However, the launch wasn’t flawless. Users reported errors and missed the tone of older models. OpenAI restored access to GPT-4o for some users. Some criticism came too — GPT-5 felt “less warm” or “sterile” to some users. Also, security researchers warned of some vulnerabilities that allowed dangerous content.
