EBU-BBC study finds almost half of AI assistant news answers have a significant flaw

Journalists at 22 public service broadcasters in 18 countries assessed more than 3,000 news answers from ChatGPT, Copilot, Gemini and Perplexity for accuracy, sourcing, context and separation of fact from opinion. Almost half of answers had at least one significant issue, roughly a third had serious sourcing problems and about one in five contained major accuracy errors such as invented or outdated facts; the problems held across languages, countries and products.
