Goldman Sachs chief executive David Solomon has denied allegations of gender discrimination against an AI programme used to set credit limits for Apple Cards

Goldman Sachs chief executive David Solomon on Thursday denied allegations of gender discrimination against an artificial intelligence programme used for setting credit limits for a new card from tech giant Apple.

A New York financial regulator said Saturday it is investigating claims that women were given lower limits on their Apple credit card by their issuer Goldman Sachs, after a cardholder's tweet about his wife's credit limit went viral.

"There's no in our process for extending credit," Solomon told Bloomberg TV on the sidelines of an economic conference in Beijing.

"There's no question that different applicants can get different results, and that can be for a variety of reasons."

A social media furore was triggered when American businessman David Heinemeier Hansson tweeted that the Apple Card is a "sexist" programme.

He said the card's "" algorithm had given him 20 times the credit limit of his wife, even though they file joint tax returns and she has a higher credit score.

A "black box" algorithm refers to AI systems whose decisions cannot be explained.

"We're going to work over time to do more to deliver more transparency to our clients," Solomon said.

Goldman Sachs spokesman Andrew Williams said earlier that the company's credit decisions do not take into account factors such as "gender, race, age, sexual orientation or any other basis prohibited by law".
