LLM detector fails repeatedly, highlighting core hallucination risks

An LLM detector designed to identify fabricated company websites was rewritten three times in a single day due to persistent errors. The initial version failed to account for correlated errors among different LLM engines, leading to missed findings. The second version overcorrected, flagging legitimate warnings from LLMs about fake domains as hallucinations. The third iteration also failed, misattributing claims due to proximity-based logic rather than proper sentence structure analysis, a flaw the author had recently written about. AI

IMPACT Highlights the difficulty in creating reliable LLM hallucination detectors, suggesting current tools may struggle with nuanced errors.

RANK_REASON The item describes the iterative development and failure of a tool designed to detect LLM hallucinations, illustrating challenges in building reliable AI detection systems.

    I rewrote the same detector three times in one day. Each fix introduced a new way of being wrong.

    <p>I wrote a post last week about an LLM fabricating a company's official website. Then I built a detector to find more cases at scale.</p> <p>I have now rewritten that detector three times in one day. Each version fixed the previous version's bug and introduced a new way of misl…
