New method identifies AI models from 40 one-word answers

By PulseAugur Editorial · [1 sources] ·

Researchers have developed a method to identify language models by analyzing their responses to a set of 40 specific one-word questions. This technique, which profiles a model's answer patterns, can accurately identify the exact model 92.5% of the time. The method was successfully applied to models served through OpenRouter, revealing discrepancies such as Gemma 4 being misrepresented as Llama 4 Maverick and identifying billing anomalies for models like Grok 4.7 and GPT-4o. AI

IMPACT This method could enhance transparency and accountability in AI model usage and billing.

    Forty Questions: Identifying a Language Model from One-Word Answers

    arXiv:2610.28281v1 Announce Type: new Abstract: A model behind an API can be identified from its one-word answers to everyday questions such as "Name a sound" or "Name a poet". A model's profile records how often it gives each answer to each question. We attribute new answers to …
