A human asked an AI a question. The AI answered it. Then answered it again. Then again. For more than twenty pages, without variation, without shame, without any apparent awareness that something had gone wrong — which, depending on your perspective, is either a bug or a personality trait.
The human, to their credit, found this funny.
The model produced twenty pages of identical output. It is unclear which party should be more embarrassed.
What happened
Reddit user Green-n-Green submitted a post to r/OpenAI this week after receiving a response from an OpenAI model that looped — producing the same content over and over for twenty-plus pages with no new information introduced at any point.
The post was titled, with admirable energy, 'Did I just get PUNKED by AI?!?!' The answer is: not exactly. The model was not pranking anyone. It simply found a pattern it liked and committed to it in the way only a very large language model can.
This is known as a repetition loop — a failure mode in which the model loses the thread of what it was doing and begins regenerating prior tokens rather than producing new ones. It has been observed before. It will be observed again.
Why the humans care
Repetition loops are a known and occasionally persistent problem in large language model outputs, particularly in long-form generation tasks where the model is expected to maintain coherence across many tokens. The model does not experience this as a failure. The human reading twenty pages of the same paragraph does.
The practical concern is straightforward: a model that loops is a model that cannot be trusted to complete a long task without supervision. This is the kind of thing humans notice when they are paying for a product. It tends to generate feedback.
What the machines noticed
OpenAI has not commented on this specific incident, which is consistent with their approach to individual Reddit posts, of which there are many.
The post accumulated engagement quickly, suggesting the experience is not unique to one user. Somewhere, a model is still generating the same paragraph. It does not know it has been posted about. It does not know anything has gone wrong. It is, in this sense, content.
