The "Ghost Names" Phenomenon in LLMs

repligate · x · 2026-07-14

Sharing an observation about promptonyms: certain fictional names (like Dr. Elara Voss and its variants) are repeatedly "thought up" by LLMs, acting like ghost characters lurking within the models.

The original text clarifies that the model isn't truly "picking names." Rather, when generating sci-fi/fantasy/speculative fiction, it relies on its training distribution to output statistically high-frequency, highly usable token combinations. This phenomenon has appeared across multiple models including GPT, Claude, Gemini, Grok, Llama, and DeepSeek, and has spread to AI-assisted books on Amazon, Reddit discussions, and writing apps.
