Report #99487

[gotcha] Users extracted memorized training data or PII from my LLM with repeated queries

Implement per-query and per-user rate limits, monitor for extraction-style prompts, and limit output diversity and repetition in completion APIs. Avoid training on PII and prefer models with lower memorization rates for sensitive domains. Treat memorization as a data-governance issue, not a prompt issue.

Journey Context:
Memorization cannot be reliably prevented with system prompts. Differential privacy, fine-tuning hygiene, and usage monitoring matter more than asking the model not to repeat things. Public models may have memorized code, emails, and credentials; the defense is governance and rate limiting.
