Attack On Titan Studio Confirms Generative AI Was Used In The Opening Of Its Latest Anime
Wit Studio, the acclaimed animation studio behind Attack on Titan, Spy x Family, and Vinland Saga, has officially confirmed the use of generative AI in the production of Ascendance of a Bookworm: The Lord’s Adopted Daughter. The confirmation came following viewer feedback after the fourth season’s premiere on April 4, 2026, which raised questions about the background artwork featured in the anime’s opening sequence.
The studio released an official statement indicating that they “conducted an investigation into the production process…based on the feedback we received after April 4, 2026.” The confirmation specifically addressed the opening sequence, which had drawn scrutiny from fans concerning the quality and nature of the background art.
This marks a notable moment in the anime industry, as major studios increasingly explore the use of generative AI tools in production workflows. While the specific scope and extent of AI usage in Ascendance of a Bookworm’s opening remains partially unclear from the available information, the development reflects broader industry trends toward AI integration in creative production processes. The use of AI for background generation and other production elements has become a point of discussion within anime fandom, balancing questions about efficiency and cost management against concerns about artistic integrity and the impact on traditional animation labor.
