What Happened — and Why It Matters
A new analysis by the BBC reveals that popular AI chatbots — including ChatGPT, Microsoft Copilot, Google Gemini and Perplexity — struggled to reliably summarize news stories. According to the review, 51% of AI-generated summaries had “significant issues”, including factual errors, mis-quotations, and misleading information.
Notably, 19% of the summaries that cited BBC content contained incorrect facts — such as wrong dates or distorted statements — and 13% of direct quotes were found to be either altered or nonexistent in the original article.
What the Study Did — and What It Found
The BBC asked AI chatbots to answer questions about 100 real news stories — covering a range of topics.
45 BBC journalists — experts in the relevant subjects — reviewed 362 AI-generated responses, checking for accuracy, fairness, context, proper sourcing, and whether opinions were clearly distinguished from facts.
The findings showed that all four major models produced a large share of flawed summaries. Some models performed worse than others: for example, Gemini had significant issues in over 60% of its responses; even the “best” model in the test had more than 40% problematic answers.
In many cases, AI failed to properly replicate the nuance of original articles — sometimes misreporting statistics, misrepresenting official positions or mis-attributing quotes.
Why This Is Worrying for News Consumers
Trust & credibility under threat: If more than half of AI-summaries are unreliable, people relying solely on AI for news — especially for fast “at-a-glance” updates — risk getting misinformed.
Misinformation cascade: Errors in AI-generated summaries can spread quickly on social media, often without the disclaimers or fact-checks human journalism would include.
False sense of comprehension: A summary may seem to give a “quick understanding,” but if it distorts key facts or context, readers may believe they know more than they actually do.
As one journalist in the review put it, the problem isn’t just minor mistakes — in many cases, “fundamental facts were wrong,” which undermines the value of using AI as a news-source substitute.
What the BBC Responsible AI team and Others Are Saying
In light of these findings, the BBC cautioned against viewing AI chatbots as reliable news summarizers — at least in their current state. They stressed that AI output must be closely edited by qualified journalists before publication.
Likewise, media-watchers and critics warn that overreliance on AI-generated news can erode public trust and make it easier for misinformation to spread — especially when summaries are consumed without access to full articles.
What This Means Moving Forward & How You Should Read News
View AI-generated summaries — especially from general-purpose chatbots — with caution. They can be useful for quick scanning, but you should verify the details against original news articles.
Encourage news outlets and platforms to label clearly when content is AI-assisted, and ensure human editorial oversight remains central.
As a reader, try to use direct sources (full-length articles, reputable journalism) instead of depending solely on second-hand summaries.
Final Take
The BBC’s analysis sends a clear message: AI chatbots are not yet — and maybe never fully will be — a safe substitute for human-checked journalism. Until AI tools consistently deliver accurate, context-rich and reliable summaries, they should be treated as helpful aids — not authoritative sources.
