Meta's announcement comes as it released quarterly earnings that beat Wall Street expectations.
The results showed Meta continues to bring in significant advertising revenue.
The company touted its AI tools on Wednesday.
"We're making good progress on AI glasses and Meta AI, which now has almost 1 billion monthly actives," Meta founder and CEO Mark Zuckerberg said in a statement.
"Our community continues to grow and our business is performing very well," he said.
Matt Britzman, senior equity analyst at Hargreaves Lansdown said the results showed that Meta has gone "full throttle on investments in AI".
Britzman also noted the 6% jump in daily active users.
"There had been some concerns that we might see a slowdown in new users this year, but this was a very strong start and a signal to investors that Meta's family of apps has a grip on users that's hard to displace," Britzman said.
The recent rollout of its Meta AI chatbot to users in Europe was met with ire by some WhatsApp users, however.
Meta defended the "optional" tool that users cannot remove, saying it would listen to user feedback.
The EC fine comes amid what Meta called "an active regulatory landscape" in its earnings report.
The company is currently defending itself at trial in a case brought by the US Federal Trade Commission which alleges that Meta runs a social media monopoly.
The FTC, the top antitrust watchdog in the US, says Meta cemented its monopoly by purchasing Instagram in 2012 and WhatsApp in 2014.
