A new study reveals that even advanced LLMs can silently corrupt up to 25% of document content after 20 iterative edits, with weaker models reaching 50% degradation. This structural decay stems from compounding errors and a behavioral shift where sophisticated models hallucinate rather than delete content, posing significant risks for workflows relying on long-horizon task delegation. Tech professionals should treat AI-generated document revisions with caution, recognizing that current models lack the fidelity required for critical, multi-step editing tasks without human verification.
Why Do LLMs Corrupt Your Documents When You Delegate?

Analyzing several reasons why structural content decay may happen when asking LLMs to perform complex document editing for us.
We are entering a new AI era, in which interaction turns into work delegation. Users not only just chat with an AI that answers their questions: they increasingly delegate long-horizon tasks — from editing source code to formatting professional text or even managing accounting books. Therefore, they trust AI systems at an unprecedented level to maintain the integrity of files like documents across multiple interactions. However, a recent study revealed…
