LLMs show bias towards favorite numbers, study finds · 1 source tracked

A data scientist named Mohd Faraaz discovered that six major large language models, including ChatGPT, Gemini, Claude, DeepSeek, Llama, and Qwen, consistently favored the number 27 when asked for a random number between 1 and 50. Only Grok deviated, choosing 42. Further testing by Javier Coronado-Blázquez in Madrid confirmed that these models exhibit favorite numbers, with larger models showing no improvement and potentially performing worse in this regard. This phenomenon occurs because LLMs treat numbers as text strings rather than quantities, and their probabilistic generation process struggles to ensure an even distribution of choices. AI

IMPACT LLMs exhibit non-random number generation biases, suggesting limitations in their understanding of quantitative concepts.

    Your Chatbot Has a Favourite Number

    <p>This is why you shouldn’t ask ChatGPT for a random number. Six chatbots out of seven, asked for something between 1 and 50, gave the same answer: 27. ChatGPT, Gemini, Claude, DeepSeek, Llama and Qwen all said it. Only Grok broke ranks, with 42 — the joke answer to the meaning …
