Model-Specific Signature Pattern

A Model-Specific Signature Pattern is a llm writing marker that uniquely identifies specific language models through characteristic output features.

• AKA: Model Fingerprint, GPT Signature, Claude Tell, Model DNA, AI Model Tell.
• Context:
  • It can typically result from Model Training Data and training methodology.
  • It can typically manifest through Vocabulary Preferences, syntactic tendencys, or formatting habits.
  • It can often enable Model Attribution Tasks for source identification.
  • It can often persist across Different Prompts and generation contexts.
  • It can often evolve with Model Version Updates and fine-tuning processes.
  • It can range from being a Subtle Model-Specific Signature Pattern to being an Obvious Model-Specific Signature Pattern, depending on its detection difficulty.
  • It can range from being a Stable Model-Specific Signature Pattern to being a Variable Model-Specific Signature Pattern, depending on its consistency level.
  • It can range from being a Single-Feature Model-Specific Signature Pattern to being a Multi-Feature Model-Specific Signature Pattern, depending on its complexity degree.
  • It can range from being a Version-Specific Model-Specific Signature Pattern to being a Family-Wide Model-Specific Signature Pattern, depending on its model scope.
  • ...
• Examples:
  • GPT Model Signature Patterns, such as:
    • GPT-4 "Delve" Pattern showing verb preference.
    • GPT-3 List Format Pattern with numbered enumeration.
    • ChatGPT Caveat Pattern using disclaimer phrases.
  • Claude Model Signature Patterns, such as:
    • Claude Structured Response Pattern with clear sections.
    • Claude Thoughtful Pause Pattern using reflection markers.
    • Claude Nuance Pattern emphasizing balanced perspectives.
  • LLaMA Model Signature Patterns, such as:
    • LLaMA Repetition Pattern showing token cycling.
    • LLaMA Format Pattern with specific structures.
  • BERT Model Signature Patterns for masked language tasks.
  • ...
• Counter-Examples:
  • Universal LLM Pattern, which appears across multiple models without specific attribution.
  • Prompt-Induced Pattern, which results from input instruction rather than model characteristic.
  • Domain Convention Pattern, which follows field-specific norms rather than model tendency.
  • Random Variation, which lacks consistent pattern for model identification.
