Days after the final release of Twitter Blue for Android, Elon Musk revealed that another paid option could be coming to Twitter soon. 

Musk tweeted that ads on Twitter were “too big” and “too frequent” and that the social media platform would soon fix the problem. “Ads are too frequent on Twitter and too big. Taking steps to address both in coming weeks,” he said in a tweet.

In a follow-up tweet, he said Twitter will soon have the option for users to pay to not see ads. “Also, there will be a higher priced subscription that allows zero ads,” Musk said in a tweet.

Musk hasn’t given a timeline for when the more expensive subscription model will arrive. He also didn’t specify how much it would cost.

Twitter currently has Twitter Blue, which costs between $8 and $11, and allows users to use many features and see “less” ads. Advertising is still part of Twitter Blue, but followers will see fewer ads than non-followers.

There are other features subscribers can get as part of Twitter Blue. Twitter Blue includes several features, such as bookmark folders, which allow Twitter Blue subscribers to group and organize their bookmarked tweets into folders for faster retrieval later. Twitter Blue offers users unlimited bookmarks and bookmark folders that are always private.

Twitter Blue also allows users to choose from a variety of color themes. Users also receive a custom app icon that they can change.

Users can also use the long-awaited tweet undo feature. This allows users to withdraw a tweet after it has been sent, before it is displayed to other Twitter users. “It’s not an edit* button, but a chance to preview and revise your Tweet before it’s posted for the world to see,” noted Twitter.
