Self-Preference Is Weak or Absent in Verifiable Instruction-Following Revision: A Four-Model Test Under Genuine Authorship
arXiv:2606.20093v1 Announce Type: new Abstract: Large language models (LLMs) increasingly review and revise text, including their own. A documented self-preference bias (models favoring their own generations when acting as judges) raises the question of whether models also resist valid corrections to their own writing. We test this in a setting where "valid" is decided not by another model but by a deterministic verifier: instruction-following revision on IFEval. A model writes a draft; the official IFEval checker confirms the draft violates a constraint and that a candidate edit fixes it; the
This research is emerging now due to the rapid advancement of large language models and their increasing deployment in complex, autonomous review and revision tasks.
Understanding LLM biases, particularly self-preference in critical tasks like verifiable instruction-following, is crucial for developing reliable and safe AI agents capable of independent operation.
This research suggests that LLMs might be more amenable to verifiable, objective corrections than previously thought, potentially easing concerns about unmitigable self-preference bias in revision tasks.

Further research and development will focus on integrating verifiable correction mechanisms into LLMs to enhance their reliability.
Increased trust in LLM-driven content revision and editing could accelerate adoption in industries requiring high precision and compliance.
This could contribute to the development of more autonomous and trustworthy AI agents capable of self-correction with objective feedback, reducing human oversight requirements.
