What Is Mechanistic Interpretability and Why It Matters for Large Language Models

The article defines mechanistic interpretability as reverse‑engineering LLMs to reveal how they represent knowledge and make decisions, explains its importance for transparency, risk mitigation, and model improvement, and surveys key techniques such as causal tracing, zero‑making, noise‑making, and logit‑lens methods with illustrative examples.

How Researchers Made Large Language Models Forget or Amplify Specific Concepts

A new study from Meta and NYU reveals a two‑step technique—SAMD to locate concept‑specific attention heads and SAMI to scale their influence—enabling precise, low‑cost editing of transformer models for tasks ranging from factual recall to safety control.

How to Edit Large Language Models: Techniques, Metrics, and Challenges

This article explains model editing—injecting or updating knowledge in AI models—distinguishes it from post‑training, outlines reliability, generalization and locality metrics, and surveys both parameter‑free (e.g., IKE) and parameter‑based methods such as ROME, hypernetworks, and MEND, highlighting practical challenges.
