Strategy positions

Security mindsetendorses

Treat safety as adversarial security; assume systems break under attack

Argues prompt-engineering insights are inseparable from security research; many widely cited LLM failure modes were first surfaced through informal prompt experiments rather than formal evaluation.

“Exploiting GPT-3 prompts with malicious inputs that order the model to ignore its previous directions.”

Context: First publicly documented prompt-injection attack against GPT-3.
