Summary.

Recursive training with synthetic data risks model collapse due to reduced diversity and error amplification. Studies highlight a 40% false reassurance rate in clinical contexts after contamination, underlining the need for robust provenance controls and real data integration to prevent irreversible degradation.

Emerging strategies prioritize entropy-based data selection and confidence-aware objectives to mitigate these risks, promoting diverse outcomes. Regulatory developments in the EU focus on transparency and traceability, aiming to prevent potential contamination, while sustained innovation in provenance standards remains crucial for AI reliability and integrity.
