Summary

Epistemic Goggles introduces a pretrained module designed to combat "Negation Neglect" in language models, where models finetuned on fictional documents still believe their core claims, identifying them as fictional only about 9% of the time. Goggles addresses this by intervening on the finetuning gradient, specifically editing the gradients an LLM LoRA receives to impart a chosen "epistemic frame"—the model's stance toward the nature of what it reads. Once trained for a specific base model, frame, and LoRA configuration, a Goggles instance can be applied frozen to new documents. Evaluations show models trained through Goggles on previously unannotated documents flag content as fictional roughly 91% of the time, while maintaining or exceeding baseline performance on GPQA and TruthfulQA. The architecture also supports other frames, such as treating documents as part of an "AI safety evaluation by Redwood Research," and the imparted frame persists even under continued finetuning.

Key takeaway

Machine Learning Engineers developing LLMs with diverse or potentially misaligned datasets should investigate Epistemic Goggles. This gradient-editing module offers a critical method to prevent "Negation Neglect," ensuring your models correctly interpret content as fictional or for safety evaluation. By imparting specific epistemic frames, you can train on challenging data without absorbing undesirable behaviors, leading to a more robust finetuning process.

Key insights

Epistemic Goggles uses gradient editing during finetuning to impart an epistemic frame, enabling LLMs to correctly identify content as fictional or for safety evaluation.

Principles

• Negation Neglect causes LLMs to "believe" fictional data.
• Gradient editing induces persistent epistemic frames.
• Frames prevent absorbing misaligned data behaviors.

Method

A Goggles module is trained once per base model, frame, and LoRA configuration. It then edits the finetuning gradients an LLM LoRA receives, imparting a chosen epistemic frame to documents without explicit annotation.

In practice

• Train LLMs on fictional data safely.
• Induce "AI safety evaluation" frames.
• Prevent absorbing misaligned model behaviors.
