Telescope: Improving Zero Shot Detection of LLM Generated Content By Measuring Token Repetition Probability
Telescope Perplexity, the average negative log probability a reference LM assigns to each token immediately after seeing it, yields strong zero-shot LLM-text detection by probing an early-training aversion to repetition.
