This edition covers news from March 24 to March 27. OpenAI Opens Its Model Spec Methodology, AI Safety Enters Engineering Phase Source: https://openai.com/index/our-approach-to-the-model-spec OpenAI published a comprehensive article detailing its “Model Spec” development methodology. This isn’t just a behavioral guideline—it’s a complete behavioral framework engineering effort. The post explains the spec’s structural design: from high-level intent to specific Chain of Command hierarchies, from hard safety boundaries to overridable default behaviors, to interpretive aids like decision rubrics and concrete examples.

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
