An appeal court judge has admitted using artificial intelligence chatbot ChatGPT to help him write a court ruling.
Lord Justice Birss said the language-processing tool was “jolly useful” and the technology had “real potential”.
Scientists, writers and other professionals have previously found ChatGPT’s accuracy unreliable since it was launched last year, and it has become known for having a “hallucination problem” in which false information is generated.

Earlier this year, ChatGPT falsely accused an American law professor by including him in a generated list of legal scholars who had sexually harassed someone, citing a non-existent The Washington Post report.
PCGuide.com says: “ChatGPT is not a truly reliable source. There’s no denying that it is one of the best artificial intelligence content-generator tools out there, but the accuracy on many topics is still not as good as you would want it to be.”
According to the Law Society Gazette, Lord Justice Birss spoke about AI, ChatGPT and generative large language models at a conference, saying: “I think what is of most interest is that you can ask these large language models to summarise information.
“It is useful and it will be used and I can tell you, I have used it.
“I thought I would try it. I asked ChatGPT can you give me a summary of this area of law, and it gave me a paragraph. I know what the answer is because I was about to write a paragraph that said that, but it did it for me and I put it in my judgment.
“It’s there and it’s jolly useful. I’m taking full personal responsibility for what I put in my judgment – I am not trying to give the responsibility to somebody else.
“All it did was a task which I was about to do and which I knew the answer and could recognise an answer as being acceptable.”
Three months ago, a New York lawyer who used ChatGPT to write a legal brief and ended up citing bogus cases profusely apologised in court.
Steven Schwartz became emotional as he explained being “duped” by the artificial intelligence chatbot.
“I deeply regret my actions in this manner that led to this hearing today,” Mr Schwartz said. “I suffered both professionally and personally [because of] the widespread publicity this issue has generated. I am both embarrassed, humiliated and extremely remorseful.”
Together with a colleague, he and their law firm were fined $5,000 (£3,935).
UK law firm Mishcon de Reya has banned lawyers from using ChatGPT because of fears they risk compromising data.
In July, two new US studies, from Stanford and UC Berkeley universities, concluded that ChatGPT appeared to be getting less accurate over time.
