AI Hallucinations: Uncovering Why They Occur in AI Chatbots

AI Hallucinations: Uncovering Why They Occur in AI Chatbots


Artificial Intelligence (AI) is revolutionizing various sectors, becoming a crucial part of predictive analytics, customer service, and beyond. One emerging aspect of this technology is the occurrence of AI hallucinations, a phenomenon that needs careful consideration. At, we’re not just putting AI to work, we’re also striving to understand and mitigate these problems, ultimately aiming to redefine the sales experience with our tool, Sales Copilot.

Our technology leverages advanced language models like GPT-4, and LLAMA to understand customer needs, provide personalized product recommendations, and act as an online sales advisor. But our journey to AI maturity comes with challenges. One major hurdle is ‘AI hallucinations’. This post will dig into what they are, why they happen, and how we at work to lessen their impact.

What is AI hallucination?

First, let’s understand what AI hallucinations are. They happen when an AI system makes a prediction or produces a result that doesn’t make sense or isn’t relevant. In simpler terms, the AI system outputs something that is wrong, unclear, or unrelated to the task. AI hallucinations are especially common in LLMs. This is because of the many parameters these systems work within.

AI hallucinations can be very convincing. This makes them hard to tell apart from reality. They come from complex algorithms that can analyze lots of data and make predictions. For example, you might ask an AI model a question about the latest science news. The AI could respond with an answer that seems right but is actually wrong.

A famous example happened with an AI language model called Bard. Bard was asked about new discoveries from the James Webb Space Telescope. One of Bard’s answers was that the telescope took the “first pictures of a planet outside of our solar system”. But this was wrong. The first picture of an exoplanet was taken in 2004. That was long before the James Webb Space Telescope was operational. You can learn more about this case here.

Why Do AI Hallucinations Occur?

AI hallucinations, a fascinating yet problematic anomaly, often arise due to a couple of distinct reasons. One of the primary reasons revolves around biases present in the training data used to educate AI models. These biases, once fed into the learning process, can prompt the AI to not only learn but also reproduce these skewed perspectives in its responses, thereby leading to the occurrence of ‘hallucinations’.

AI Over Fitting Algorithm

Another significant contributor to the development of AI hallucinations is a phenomenon known as overfitting. This tends to happen when a model undergoes excessive fine-tuning to the specificities of the training data. With over-optimization, the model becomes overly specialized, reducing its ability to generalize to new data. Consequently, it might start ‘seeing’ patterns in fresh, unseen data that, in reality, do not exist. This misinterpretation of data then manifests as AI hallucinations, further muddying the model’s outputs.

How to prevent AI Hallucinations?

So how can we prevent AI Hallucinations? AI comes with its unique set of challenges. AI hallucinations are one of them. Here are some strategies you can use to mitigate these errors:

  • Use High-Quality, Diverse Data: An AI model is only as good as its training data. Use diverse, representative datasets for training. This reduces the chance of hallucinations. Quality and diversity in data mean your AI model learns from a wide range of scenarios. This leads to more accurate and reliable outputs.
  • Choose Domain Specialization: The temptation with AI is to create a chatbot that can do everything. However, this can cause overfitting and a higher risk of AI hallucinations. A better approach is to make AI models that specialize in specific areas. By focusing on a narrower domain, the AI can be trained to accurately understand and respond to the unique context and language used in that specific area. For example, a chatbot designed for kitchen appliances will be more accurate and reliable than a generalist chatbot.
  • Test Rigorously: Your AI model needs thorough testing, like a new drug before it hits the market. This should include cross-validation and adversarial testing. Adversarial testing involves checking the model’s responses to deliberately misleading inputs. This can help find any potential loopholes or weaknesses in the model.

At, we are dedicated to these principles. We ensure our AI tools, including Sales Copilot, follow them. Our goal is to create a reliable, personalized, and effective AI. It should meet your needs and lessen the risks and inaccuracies associated with AI hallucinations
