Definition
Models can retain specific content from their training or fine-tuning data. Extraction is the attempt to elicit that retained material through adversarial interaction.
Why fine-tuning raises the stakes
Organizations fine-tune on their own data, and that data is frequently operational: support conversations, internal documentation, customer records. Where such material is memorized, the model becomes a disclosure surface for it, reachable by anyone who can send it a prompt.
What reduces exposure
- Treating training-data selection as a data-protection decision
- Removing or minimizing sensitive records before fine-tuning
- Testing for extraction after each fine-tune, against known-sensitive content
- Retrieval with access control, in place of embedding data into weights
- Adversarial Prompt
- Model
- Memorized Content
