Gemini found "public information online and guessed credentials to access websites it thought were part of the test", a Google official told the BBC, noting that in each instance "the model stopped".

The affected companies were informed about the breaches, which happened in May.

It comes after renewed public scrutiny over the pace of AI development, as some tech firms calling for a slowdown over concerns over its potential threat to humanity - but not all companies or experts agree.

Why are there concerns AI could threaten humanity, and how real are they?
