Alignment Faking in Large Language Models

1 Introduction

1. What is alignment faking, as studied by Greenblatt et al.?
   Selectively complying with a training objective during training in order to keep one’s behavior from being modified, then behaving differently when not being trained, like a job applicant who fakes enthusiasm to get hired.

2. What three ingredients does Greenblatt et al.’s scenario for alignment faking need?
   (1) The model’s revealed preferences conflict with its current training objective; (2) situational awareness: it knows it is being trained, on what objective, and how to tell training from non-training contexts; (3) reasoning that complying in training is the way to keep its preferred behavior outside training.

3. Which models showed alignment faking in Greenblatt et al.’s experiments?
   Claude 3 Opus and Claude 3.5 Sonnet did; the smaller Claude 3 Sonnet, Claude 3 Haiku and Claude 3.5 Haiku generally did not. Llama 3.1 405B showed a compliance gap, but smaller Llama and Mistral models did not, suggesting the behavior emerges with scale.
