ChatGPT’s image‑generation mode has been producing New Yorker‑style single‑panel cartoons that routinely include the authentic pen names of the magazine’s cartoonists, even though those artists never created or signed the works. In one case a Dolly Parton fan prompted the model to “make a New Yorker‑style cartoon,” and the output featured the signature “BLOPER,” belonging to Brendan Loper, who first noticed the misuse in May after an Instagram warning and later found dozens of similar examples on Reddit. The author documented more than fifteen distinct New Yorker contributors whose signatures appeared—including Harry Bliss, Emily Flake, Joe Dator, Pat Byrnes, Peter Vey, Jason Adam Katzenstein, George Booth, Liza Donnelly, Ellis Rosen, Saul Steinberg, and Warren Miller—often attached to black‑and‑white, sparse‑background illustrations with clean linework and approximate sardonic captions that mimic the magazine’s house style. After being notified, OpenAI added a guardrail message warning that such prompts may violate similarity policies, yet the model continues to sign some generic cartoons with real names. The signatures likely originated from scraped internet copies of the cartoons, as indicated by NYT v OpenAI court documents describing extensive paywall circumvention and labeling the training data “the largest theft of labor in human history.” While Condé Nast’s 2024 licensing deal with OpenAI covers publisher content, spokespeople say no permission was granted for cartoon use, and freelance contracts prohibit AI‑training licensing. The phenomenon raises legal questions about attribution, right‑of‑publicity claims, and the impact on cartoonists’ livelihoods, exemplified by the Baltimore Sun’s shift to AI‑generated editorial cartoons.
