OpenAI<\/a> on Thursday announced GPT-5, its latest and most advanced large-scale artificial intelligence<\/a> model.<\/p>\n The company is making GPT-5 available to everyone, including its free users. OpenAI said the model is smarter, faster and “a lot more useful,” particularly across domains like writing, coding and health care.<\/p>\n “I tried going back to GPT-4, and it was quite miserable,” OpenAI CEO Sam Altman said in a briefing with reporters.<\/p>\n Since launching its AI chatbot ChatGPT in 2022, OpenAI has rocketed into the mainstream. The company said it expects to hit 700 million<\/a> weekly active users on ChatGPT this week, and it is in talks with investors about a potential stock sale at a valuation of roughly $500 billion, as CNBC previously reported<\/a>.<\/p>\n OpenAI said GPT-5’s hallucination rate is lower, which means the model fabricates answers less frequently. The company said it also carried out extensive safety evaluations while developing GPT-5, including 5,000 hours of testing.\u00a0<\/p>\n Instead of outright refusing to answer users’ questions if they are potentially risky, GPT-5 will use “safe completions,” OpenAI said. This means the model will give high-level responses within safety constraints that can’t be used to cause harm.\u00a0<\/p>\n “GPT-5 has been trained to recognize when a task can’t be finished, avoid speculation and can explain limitations more clearly, which reduces unsupported claims compared to prior models,” said Michelle Pokrass, a post-training lead at OpenAI.<\/p>\n During the briefing, OpenAI demonstrated how GPT-5 can be used for “vibe coding,” which is a term for when users generate software with AI based on a simple written prompt.\u00a0<\/p>\n The company asked GPT-5 to create a web app that could help an English speaker learn French. The app had to have an engaging theme and include activities like flash cards and quizzes as well as a way to track daily progress. OpenAI submitted the same prompt into two GPT-5 windows, and it generated two different apps within seconds.\u00a0<\/p>\n The apps had “some rough edges,” an OpenAI lead said, but users can make additional tweaks to the AI-generated software, like changing the background or adding additional tabs, as they see fit.<\/p>\n GPT-5 is rolling out to OpenAI’s Free, Plus, Pro and Team users on Thursday. This launch will be the first time that Free users have access to a reasoning model, which is a type of model that “thinks,” or carries out an internal chain of thought, before responding. If Free users hit their usage cap, they’ll have access to GPT-5 mini.<\/p>\n OpenAI’s Plus users have higher usage limits, and Pro users have unlimited access to GPT-5 as well as access to GPT-5 Pro. ChatGPT Edu and ChatGPT Enterprise users will get access to GPT-5 roughly a week from Thursday.<\/p>\n “It’s hard to believe it’s only been two and a half years since @sama joined us in Redmond to show the world GPT-4 for the first time in Bing, and it’s incredible to see how far we’ve come since that moment,” Microsoft CEO Satya Nadella wrote in a\u00a0Thursday X post<\/a>, referring to OpenAI CEO Sam Altman’s appearance at Microsoft headquarters in Washington in February 2023.<\/p>\n The new model is coming to Microsoft products Thursday, according to a company\u00a0blog post<\/a>. Microsoft 365 Copilot is getting GPT-5, as well as the Copilot for consumers and the Azure AI Foundry that developers can use to incorporate AI models into third-party applications.<\/p>\n
