TikTok is now disputing a Reuters report that claims the short-video app is cloning its algorithm to potentially offer a different version of the app, which might degrade over time, just for US users.

Sources "with direct knowledge" of the project—granted anonymity because they're not authorized to discuss it publicly—told Reuters that the TikTok effort began late last year. They said that the project will likely take a year to complete, requiring hundreds of engineers to separate millions of lines of code.

As these sources reported, TikTok's tremendous undertaking could potentially help prepare its China-based owner ByteDance to appease US lawmakers who passed a law in April forcing TikTok to sell its US-based operations by January 19 or face a ban. But TikTok has maintained that the "qualified divestiture" required by the law would be impossible, and on Thursday, TikTok denied the accuracy of Reuters' report while reiterating its stance that a sale is not in the cards.
