The Instruction Hierarchy: Training LLMs to Prioritize Privileged Instructions
OpenAI just published the defense playbook against prompt injection attacks—and it's simpler than you think.

Why it matters
As LLM deployment scales in production systems, prompt injection vulnerabilities pose real business risk. OpenAI's instruction hierarchy framework offers a practical governance model for prioritizing system instructions over user inputs—critical for leaders shipping AI agents and multi-tenant applications.
