This edition covers news from 03-09 to 03-10. AI labs / official announcements OpenAI: Improving instruction hierarchy in frontier LLMs OpenAI introduced what it calls the “IH-Challenge”: a training/evaluation approach aimed at making models follow instruction hierarchy more reliably. The practical goal is simple: system instructions should outrank developer instructions, which should outrank user instructions—without being “talked out of it” by downstream prompts. They frame it as a safety-and-product problem at the same time: better steerability and stronger resistance to prompt injection. Link: https://openai.com/index/instruction-hierarchy-challenge
