AI models don't hallucinate, they guess based on prompts

Large language models do not "hallucinate" in the human sense; rather, they are next-token predictors that generate the most probable continuation of a given input. When an LLM produces an incorrect output, it is because the prompt was underspecified, leaving the model to make probable guesses rather than retrieve factual information. To improve accuracy, users should focus on providing highly specific prompts with clear constraints on inputs, outputs, and dependencies, rather than relying on vague instructions. AI

IMPACT Users must provide highly specific prompts to LLMs to avoid "guessing" and ensure accurate outputs.

    Your AI assistant is not hallucinating. It's guessing, and you asked it to guess.

    <p>Andrej Karpathy said it plainly in 2023: language models do not know they are wrong. They have no internal signal that flags uncertainty. They generate the most probable continuation of whatever you gave them, and they do it with the same confidence whether the output is corre…
