A deep dive into synthetic data: how AI-generated training data is replacing real data in many applications, the quality challenges, and the risk of model collapse when models are trained on outputs of other models.

Charrington identifies the recursive problem: as AI-generated content floods the internet, future models will be trained on a mixture of human and AI content. This polluted training environment will shape the capabilities and biases of future models in ways that are difficult to predict or control.

Model collapse — when models trained on synthetic data from other models progressively degrade — is the AI equivalent of a copy-of-a-copy degradation
When model B is trained on synthetic data generated by model A, and model C is trained on synthetic data from model B, each generation loses fidelity to the original data distribution. The tails of the distribution are clipped first, leading to progressive homogenization and quality degradation.Was this useful?
