[gotcha] Training data can be extracted from production aligned models at scale

Assume memorization: avoid putting sensitive PII, secrets, or proprietary text in pre-training or fine-tuning data; implement differential privacy or data deduplication; monitor for divergence-style extraction prompts; and treat model outputs as potentially containing training data.

Journey Context:
Alignment and safety tuning do not erase memorization. Carlini et al. showed gigabytes of training data can be extracted from production models using divergence attacks that make the model leave its chatbot distribution. The common mistake is believing alignment equals privacy.
