GPT-5 is the latest version of OpenAI's large language model OpenAI has released its newest AI model, GPT-5, two years after rolling out GPT-4, whose success has driven ChatGPT towards world domination. But despite promises of a similar jump in capability, GPT-5 appears to show little improvement over other leading AI models, hinting that the industry may need a fresh approach to build more intelligent AI systems. OpenAI's own pronouncements hail GPT-5 as a "significant leap in intelligence" from the company's previous models, showing apparent improvements in programming, mathematics, writing, health information and visual understanding. It also promises less frequent hallucinations, which is when an AI presents false information as true. On an internal benchmark measuring "performance on complex, economically valuable knowledge work", OpenAI says GPT‑5 is "comparable to or better than experts in roughly half the cases… across tasks spanning over 40 occupations including law, logistics, sales, and engineering."

Users of the free version of ChatGPT or ChatGPT were not included. OpenAI is not the first to offer such legal protection, though as the creator of the wildly popular ChatGPT, which Altman said has 100 million weekly users, it is a heavyweight player in the industry. Google, Microsoft and Amazon have made similar offers to users of their generative AI software. Getty Images, Shutterstock and Adobe have extended similar financial liability protection for their image-making software. Altman made the announcement at OpenAI's first ever developer conference, meant to attract programmers working with ChatGPT.
