Don't use ChatGPT for ..., says head of ChatGPT Nick Turley in an important 'warning' to users

OpenAI's much-anticipated

GPT-5

language model promises to be the company's most powerful and accurate AI to date, but the tech giant is still urging users to treat its popular chatbot,

, with caution. Despite significant improvements, the company warns that the system is not yet a reliable primary source of information. In an interview with The Verge,

Nick Turley

, Head of ChatGPT, said that the chatbot should be considered a "second opinion." He acknowledged that GPT-5, while an improvement, still struggles with hallucinations—a term for when the AI generates information that sounds convincing but is factually incorrect.According to Turley, OpenAI has reduced these errors significantly, but the model still gives incorrect responses approximately 10% of the time. Turley stressed that achieving 100% reliability is a monumental challenge.

ChatGPT head Nick Turley's 'warning' to users

"Until we are provably more reliable than a human expert across all domains, we'll continue to advise users to double-check the answers," Turley said. "I think people are going to continue to leverage ChatGPT as a second opinion, versus necessarily their primary source of fact."

Large language models like GPT-5 are trained to predict words and patterns from massive datasets. While this allows them to generate incredibly natural and human-like responses, it also leaves them prone to providing false information on unfamiliar or complex topics. To combat this, OpenAI has connected ChatGPT to search, enabling users to verify its answers with external sources.Turley expressed confidence that the issue of hallucinations will eventually be solved but cautioned that a quick fix is not on the horizon. "I'm confident we'll eventually solve hallucinations, and I'm confident we're not going to do it in the next quarter," he stated.Meanwhile, OpenAI's ambitions continue to grow. The company is reportedly working on its own browser, and CEO Sam Altman has even hinted at the possibility of buying Google Chrome if it were ever made available for sale. "If Chrome is really going to sell, we should take a look at it," referring to potential antitrust actions that may force Google to sell the Chrome browser.
