For a live performance, the DJ created lyrics and raps imitating the US star on two artificial intelligence websites.
The French producer has stated that he will not commercially release the track. Guetta won the award for best producer at Saturday’s ceremony.
However, he stated that he anticipates musicians using AI to create new sounds in the future, “every new music style comes from a new technology”.
Speaking to BBC music correspondent Mark Savage at the Brit Awards, Guetta said: “I’m sure the future of music is in AI. For sure. There’s no doubt. But as a tool.”
“Nothing is going to replace the taste,” he said. “What defines an artist is, you have a certain taste, you have a certain type of emotion you want to express, and you’re going to use all the modern instruments to do that.”
He compared AI to instruments that have led to musical revolutions in the past.
“Probably there would be no rock ‘n’ roll if there was no electric guitar. There would be no acid house without the Roland TB-303 [bass synthesizer] or the Roland TR-909 drum machine. There would be no hip-hop without the sampler.
“I think really AI might define new musical styles. I believe that every new music style comes from a new technology.”
In a video he posted last week, Guetta said he created the Eminem-style vocal “as a joke” but “it worked so good, I could not believe it”.
“It’s very funny, actually, because a lot of people are reacting. Some of them are like, ‘Oh, this is genius.’ Some of them are getting super mad at me, but I’m not going to release the record.
“It is impossible to think that it’s a real collab, but it sounds exactly like him [Eminem],” he added.
Last week, Variety reported that TikTok has seen an increase in the number of AI-generated songs going viral, with fans using software to make existing songs sound like another artist is singing them.
Fans of Drake began using an artificial intelligence generator a month ago to make their own songs in the style of the Canadian rapper.
A harsh critique of an artificial intelligence system that attempted to write a song “in the style of Nick Cave” was also written by Nick Cave in January.
The outcomes were dubbed “a grotesque mockery” and “a travesty” by the singer.
