model collapse

Model collapse refers to the declining performance of generative AI models that are trained on AI-generated content.

What Is Model Collapse? | IBM Alice Gomstyn 2025

It feels like building a house that during construction you realize it has issues, but instead of easily fixing it you let it fall apart. Model collapse can be corrected. It's not some inevitable thing as if AI is just a ball rolling down a hill

We find that indiscriminate use of model-generated content in training causes irreversible defects in the resulting models, in which tails of the original content distribution disappear. We refer to this effect as ‘model collapse’ and show that it can occur in LLMs as well as in variational autoencoders (VAEs) and Gaussian mixture models (GMMs).
