Frequently Asked Questions

What is an AI hallucination?

An AI hallucination occurs when a generative model produces information that is factually incorrect, nonsensical, or not supported by the underlying data, yet presents it with a high degree of confidence. This happens because LLMs are designed to predict the next likely token in a sequence based on training patterns rather than verifying facts against a verified source of truth.

How do I measure the reliability of my AI system?

You can measure reliability by implementing automated evaluation frameworks that compare model outputs against ground truth datasets or by using LLM-as-a-judge techniques. Tools like RAGAS and DeepEval allow developers to quantify metrics such as faithfulness, answer relevance, and context precision, providing a score that helps identify when a model is drifting into inaccuracies.

Is it possible to stop hallucinations completely?

While it is currently impossible to eliminate hallucinations entirely in non-deterministic generative models, you can significantly mitigate them using RAG (Retrieval-Augmented Generation) architectures and proactive guardrails. By providing the model with verified, context-specific documents and using security layers like Lakera Guard to filter inputs and outputs, businesses can reduce the frequency of errors to an acceptable production threshold.

Why do I need observability tools if my AI works fine in testing?

AI models often behave differently in production environments compared to controlled testing scenarios due to varying user inputs and evolving data distributions. Observability tools allow you to track performance in real-time, log traces for debugging, and detect drift, ensuring that your system remains accurate and reliable even as your user base and data complexity grow.
