How Does GPTZero Work?

GPTZero works by analyzing text for certain indicators, such as perplexity and burstiness.

GPTZero’s Analysis Indicators

GPTZero uses two measures to determine if a text is human-generated:

  • Perplexity
  • Burstiness

Perplexity as a Complexity Indicator

Perplexity is a measure of how complex or random a text might be. If GPTZero is “perplexed” by the text it is evaluating, then it is more likely to be authored by a human.

Burstiness as an Authorship Indicator

Burstiness refers to the presence of shorter, highly concentrated sections of text within a longer piece. GPTZero uses burstiness as an indicator of human authorship.

How GPTZero Analyzes Text

GPTZero analyzes text by considering two key indicators:

1. Perplexity

GPTZero uses perplexity to measure the complexity or randomness of a given text. Higher perplexity values indicate higher complexity, which suggests that the text is more likely to be authored by a human. Perplexity is calculated based on the prediction accuracy of the model for the next word in a sequence.

  • Perplexity can be influenced by the use of rare or uncommon words or phrases in the text.
  • If GPTZero encounters a higher perplexity value, it indicates that the text is more intricate and may have been authored by a human.
  • A lower perplexity value may suggest that the text is more predictable and likely computer-generated.
  • It is important to note that perplexity alone is not a definitive indicator of human or AI authorship, but it provides valuable insights for analysis.

2. Burstiness

GPTZero also looks for burstiness in text to identify patterns and identify sections of highly concentrated content. Burstiness is commonly observed in natural human writing and is less prominent in computer-generated or AI-authored text.

Some key points about burstiness:

  • Burstiness is characterized by shorter sections of text within a longer piece that contain a high density of information or ideas.
  • If GPTZero detects burstiness in a text, it is more likely to be authored by a human.
  • The presence of bursts suggests that the writing process involved creative thinking and iterative composition.

Conclusion

GPTZero utilizes perplexity and burstiness as key indicators to analyze text and infer its authorship. Perplexity measures the complexity of text based on the model’s prediction accuracy, whereas burstiness detects the presence of concentrated content sections within longer pieces. By considering these indicators, GPTZero provides insights into whether a given text is likely to be authored by a human or generated by AI.
