AI Hallucinations

A phenomenon in large-language-models (LLMs) where models generate plausible but factually incorrect information, often appearing coherent and reasonable to users.

Key Points

  • Not a minor bug but a widespread issue affecting most LLMs during generation
  • Occurs when models produce outputs that are contextually consistent but factually inaccurate
  • Root cause lies in probabilistic nature of training data and lack of real-world grounding
  • Common in complex reasoning, historical facts, and technical domains
  • Recent analysis (via Gemini 2.5 Flash summary) emphasizes the pervasive nature of these errors in large-language-models
