Latent Knowledge Analysis via Feature-Based Causal Tracing

Letlotlo

Details

Summary

This project explores how factual knowledge is stored in large language models using Goodfire’s Ember API. By identifying and manipulating internal features related to specific facts, it shows how facts are encoded and how model behavior changes when those features are amplified or erased.

Deception Detection Hackathon: Preventing AI deception

Mar 18, 2025

Safe ai

The rapid adoption of AI in critical industries like healthcare and legal services has highlighted the urgent need for robust risk mitigation mechanisms. While domain-specific AI agents offer efficiency, they often lack transparency and accountability, raising concerns about safety, reliability, and compliance. The stakes are high, as AI failures in these sectors can lead to catastrophic outcomes, including loss of life, legal repercussions, and significant financial and reputational damage. Current solutions, such as regulatory frameworks and quality assurance protocols, provide only partial protection against the multifaceted risks associated with AI deployment. This situation underscores the necessity for an innovative approach that combines comprehensive risk assessment with financial safeguards to ensure the responsible and secure implementation of AI technologies across high-stakes industries.
