AI Hallucinations: How to Ensure Reliable Responses?
1. What is an AI hallucination?
AI hallucinations occur when a conversational agent, such as a chatbot, generates an incorrect, incoherent, or completely fabricated response. These errors are not due to a technical bug, but rather to the way language models process data. In the absence of relevant information in its database, the AI may attempt to "guess" a plausible answer, even if it is wrong.
Why does this problem occur?
Artificial intelligence models, particularly LLMs (Large Language Models), are designed to predict the next word or phrase based on context. They do not "know" if an answer is correct, but rather assess the likelihood that it is.
This can lead to misleading or inconsistent answers, especially if:
- The user's question exceeds the knowledge contained in the database.
- The available information is ambiguous or poorly structured.
- The AI has not been configured to validate its answers in a given context.
Key Definition
An AI hallucination refers to a response generated by an AI model that lacks a solid factual basis. It is a plausible but incorrect response.
Let's take an example in the field of e-commerce. Here is a typical scenario where a hallucination could occur:
Customer Support for E-commerce
Example 1: Delivery Issue
AI Assistant
Online
Identified Problem:
- Error generated by AI: The response given indicates a timeframe of "less than one day". However, the actual timeframe is 2 to 4 business days.
- Possible consequences:
- Customer frustration, who expects a quick delivery.
- Negative reviews, disputes, or refunds to manage for the company.
2. Why do AI hallucinations pose a problem?
1. Loss of user trust
When the responses provided by an AI agent are incorrect, users quickly question the reliability of the system. A dissatisfied customer from a service or a poorly informed chatbot is less likely to return.
Customer Impact
A single incorrect response can be enough to lose a customer.
Key statistic: 86% of users report that they avoid a brand after a bad experience with its customer service.
2. Financial consequences
Incorrect information can lead to indirect costs:
- Refunds for orders or product returns.
- Increased interactions with human support to resolve errors.
- Decreased sales due to negative reviews or loss of trust.
Attention !
The financial impacts of hallucinations can escalate quickly. Each unresolved dispute or refund can also generate operational costs.
