Who produced Taylor Swift’s song “august” alongside her?

Jack Antonoff produced Taylor Swift’s “august” alongside Swift. The pair are the principal credited producers on the track, continuing a collaboration that had already produced songs on several earlier Swift albums.

Antonoff created the instrumental foundation before Swift wrote the lyrics. The finished production uses dense reverb, strings, keyboards, and guitar textures to create a hazy, cinematic sound. Those choices reinforce the song’s memory-like portrayal of a fleeting summer relationship.

Joe Alwyn is also associated with the production of “august.” The Recording Academy recognized him as a co-producer after Folklore won Album of the Year at the 63rd Annual Grammy Awards, although the album’s liner-note credits list Swift and Antonoff as producers.

This distinction explains why trivia answers can differ when asking about the track’s production. Jack Antonoff is the specific collaborator credited alongside Swift in the standard song listing, while Alwyn’s later recognition adds another production credit connected to the recording.
