Meta says it is acquiring the Chinese-founded AI firm Manus as it looks to boost the capabilities of its tech.
Bloomberg analysts and The Wall Street Journal suggested the purchase could be worth more than $2bn (£1.48bn).
Meta said the deal would help improve its own AI by giving people access to "agents" - tools which can do complex things with minimal user interaction such as planning trips or making presentations.
"Manus's exceptional talent will join Meta's team to deliver general-purpose agents across our consumer and business products, including Meta AI," it said in a blog post.
Barton Crockett, analyst at Rosenblatt Securities, told Reuters it was a "natural fit" for Meta, which extended into boss Mark Zuckerberg's "vision of personal AI" using agents.
