How to Avoid ChatGPT Hallucinations and Why They Matter

Written by Nexlogica Team

June 9, 2023


ChatGPT is a powerful AI language model that can generate coherent and engaging texts on almost any topic. It can also converse with humans in a natural and fluent way, making it a useful tool for various applications such as education, entertainment, and customer service.

However, ChatGPT is not perfect. Sometimes, it can produce texts that are inaccurate or misleading. These are called hallucinations, and they can have serious consequences for the users and the society.

What are ChatGPT Hallucinations?

Hallucinations are mistakes in the generated text that are semantically or syntactically plausible but are in fact incorrect or nonsensical. For example, ChatGPT might generate a plausible-sounding answer to a factual question that is completely incorrect, such as an erroneous date for the creation of the Mona Lisa.

Hallucinations can also occur when ChatGPT generates text that is inconsistent with the context or the previous dialogue. For example, ChatGPT might switch topics abruptly, repeat itself, contradict itself, or introduce irrelevant information.

Hallucinations can arise when using ChatGPT because the AI language model has been trained on vast amounts of data that include a wide range of information, including both factual and fictional material. When using ChatGPT, you’re essentially asking it to generate text for you based on its internal representation of the data it has seen. However, this representation is not always accurate or complete, and it can be influenced by noise, bias, or randomness.

The hallucination rate for ChatGPT is roughly 15% to 20%, which means that one out of every five or six texts generated by ChatGPT might contain some form of hallucination. This is a significant problem that limits the reliability and trustworthiness of ChatGPT and other AI platforms.

Why do ChatGPT Hallucinations Matter?

ChatGPT hallucinations matter because they can have negative impacts on the users and the society. Depending on the domain and the purpose of using ChatGPT, hallucinations can cause confusion, misinformation, deception, or even harm.

For example, if you use ChatGPT to write a book report or a historical essay for school, you might end up with a text that contains false or inaccurate facts that could affect your grade or your learning. If you use ChatGPT to get medical advice or legal information, you might end up with a text that contains harmful or misleading suggestions that could affect your health or your rights. If you use ChatGPT to chat with a friend or a stranger online, you might end up with a text that contains offensive or inappropriate remarks that could affect your relationship or your reputation.

Moreover, ChatGPT hallucinations matter because they can affect the public perception and acceptance of AI technologies. If people encounter hallucinations when using ChatGPT or similar AI models, they might lose trust in them and become skeptical or fearful of their capabilities and intentions. This could hamper the adoption and innovation of AI technologies that could otherwise benefit the society.

How to Avoid ChatGPT Hallucinations?

There are several ways to avoid or reduce ChatGPT hallucinations when using it for various purposes. Here are some tips:

1. Use specific and clear prompts

When asking ChatGPT to generate text for you, try to provide as much detail and context as possible. This can help ChatGPT understand your intent and generate relevant and accurate texts. For example, instead of asking “Who is Albert Einstein?”, you could ask “Who is Albert Einstein and what are his contributions to physics?”.

2. Use multiple sources

When using ChatGPT to get information or opinions on a topic, try to cross-check the generated text with other sources such as books, websites, or experts. This can help you verify the accuracy and validity of the text and avoid being misled by hallucinations. For example, instead of relying on ChatGPT’s summary of a court case, you could also read the original documents or consult a lawyer.

3. Use feedback mechanisms

When using ChatGPT to converse with someone or create content for someone else, try to use feedback mechanisms such as ratings, reviews, comments, or corrections. This can help you identify and correct any hallucinations in the generated text and improve the quality and usefulness of the text. For example, instead of accepting ChatGPT’s code suggestion blindly, you could also run it, test it, or review it with a programmer.

Conclusion

ChatGPT is an impressive AI language model that can generate texts on almost any topic and converse with humans in a natural and fluent way. However, it is not perfect and sometimes it can produce texts that are inaccurate, misleading, or nonsensical. These are called hallucinations, and they can have serious consequences for the users and the society.

To avoid or reduce ChatGPT hallucinations, you can use specific and clear prompts, use multiple sources, and use feedback mechanisms when using ChatGPT for various purposes. By doing so, you can enjoy the benefits of ChatGPT while minimizing the risks of hallucinations.
