October 6, 2026 • Automated summary
At a glance
- ChatGPT and other image models are generating fake New Yorker-style cartoons that include real cartoonists' signatures, learned as a stylistic pattern from training data.
- The tech community sees this as an unsurprising but technically unresolved artifact, while framing it as a vivid example of the broader 'plagiarism machine' critique.
- The incident sharpens ongoing debates around copyright washing, identity misuse, and the limits of current model guardrails.

When the Model Learns the Signature as Just Another Brushstroke
According to Nieman Lab, ChatGPT is producing fabricated New Yorker-style cartoons that come complete with the signatures of real, identifiable cartoonists — people who never drew the images in question. The root cause is almost banal: nearly every New Yorker cartoon in the training corpus carries a signature, so the model internalizes that mark as an intrinsic visual feature of the genre rather than as a legal or identity marker tied to a specific human. This is not a one-off hallucination but a structural consequence of how diffusion and multimodal models reproduce statistical regularities in their data. Crucially, the problem spans multiple platforms, with technical users confirming the same behavior in Google's Nano Banana Pro and across ChatGPT's image generations. It is surfacing now because image generation has become good enough that these artifacts are both convincing and widely shared — making the forged signatures impossible to ignore.
A Known Bug, a Familiar Grievance
The community reaction splits cleanly between technical resignation and ethical frustration. On the technical side, users like gwern treat this as a well-documented, cross-model artifact that currently requires manual post-editing to remove — effectively a persistent, unfixed bug rather than a surprise. On the critical side, commenters seize on the incident as a tidy, almost comedic confirmation of the 'plagiarism machine' framing, with some half-seriously raising fraud or identity-theft angles. There is little celebration here; the dominant mood is a mix of 'we told you so' skepticism and weary acknowledgment of an engineering shortcoming.
“The copyright washing machine strikes again.”
“This has been a perennial problem with my own generated comics with both Nano Banana Pro and ChatGPT (all generations). I often have to put in an extra edit to erase the false signature.”
