Research from AIRI and Skoltech evaluated the utility of Large Language Models for generating synthetic toxic text, revealing that LLM-generated data consistently lacked lexical diversity, which negatively impacted the performance of downstream text detoxification models.

Key insights

  • LLM-generated toxic text exhibits a significant 'lexical diversity gap,' characterized by a small, repetitive vocabulary of insults and profanities.
  • This lack of diversity in synthetic training data leads to detoxification models that generalize poorly to the broader, nuanced spectrum of human-generated toxic language.
  • Simply increasing the scale of the LLM (e.g., from 8B to 72B parameters) did not inherently resolve the problem of repetitive toxic output or improve lexical diversity.
