Hallucinations

Exclusive: Inaccurate information presented in summaries, Guardian investigation finds

In this talk, Ian Griffiths addresses the common misconception about 'hallucinations' in AI. Often seen as a bug, hallucinations are actually a critical feature of modern AI's ability to contextualize language.

Ian discusses how AI fabricates plausible but sometimes inaccurate information and why understanding this behaviour is crucial for leveraging AI effectively. Through detailed examples and comparison with human comprehension, he illustrates that AI's so-called hallucinations are a natural part of their functioning and can be harnessed to build better systems.

Video Summary:

Artificial intelligence is doing some pretty mind-blowing things lately,
writing articles, generating images, passing bar exams and even composing music.

But as powerful as AI can be, it's not immune to quirks and issues.
One of the most talked-about (and arguably misunderstood) issues is what is referred to as AI hallucination.

So, What Is an AI Hallucination?

AI hallucinations happen when a model like ChatGPT confidently spits out information that’s just plain wrong. It might tell you an historical fact that never happened, cite a study that doesn’t exist or describe a product feature that isn't even real.

What’s especially tricky is that the response often sounds totally believable, clear, authoritative and logical. But under the hood, it’s complete fiction, and it's pretty much impossible to tell the difference if you don't have specialised knowledge.

Of course, the term “hallucination” is borrowed from psychology, where it describes seeing or hearing things that aren’t really there. And, in the AI world, it refers to when a machine essentially "imagines" facts that aren’t supported by its training data or real-world information.

Why Do These Hallucinations Happen?

There’s no single cause, but there are a few reasons that stand out from the rest. First, hallucinations can occur more frequently if there are data gaps or biases in data. Of course, AI models learn from huge amounts of text that is scraped from all corners of the internet, books, articles and more.

So, basically what happens is that if there's a gap in the data or if the data is actually inaccurate or biased, the model ends up having to make things up to fill in the blanks, so to speak.

Second, sometimes AI models are simply trying to guess and complete patterns. They're trained to predict the next word to come in a sentence based on what they've seen before. But sometimes, the pattern they end up choosing might sound right to the AI but it doesn't actually align with accurate facts.

Third and finally, we need to remember that as incredibly intelligent as AI may seem, it doesn't have real-world understanding. It has no awareness
no memory (although new models are starting to have memory of past conversations) or access to updated databases, unless they're specifically integrated.

Essentially, they're just guessing what kind of sounds right rather than evaluating and double-checking facts.

Should We Be Worried?

Honestly, yes and no. On one hand, AI hallucinations can be pretty harmless. If a chatbot mistakenly tells you that a fictional character was born in 1856, it’s probably not the end of the world.

However, the stakes get a lot higher when AI is used in medicine, law, journalism or customer service. Imagine an AI system giving a patient inaccurate medical advice or misrepresenting a legal precedent - that's obviously a serious problem. And, since these hallucinated answers can sound super confident, they can be very persuasive even when they’re wrong.

This is why AI developers, including those at Anthropic, OpenAI, and others, are spending a lot of time and energy trying to reduce hallucinations. They’re using techniques like Retrieval Augmented Generation (RAG),
Reinforcement Learning with Human Feedback (RLHF) and extra fact-checking layers. These methods are helpful, but they're not solving the problem entirely.

The Bottom Line

AI hallucinations are a reminder that, for all its brilliance, artificial intelligence is still a work in progress. As models get more sophisticated, the hope is that they’ll get better at knowing when not to speak - or at least when to say, “I’m not sure.” But hey, even humans struggle to do that sometimes (probably more than we'd like to admit).

Until then, it’s on us to ask questions, cross-check facts and remember: just because something sounds smart doesn’t mean it’s true. Even when it comes from a robot.

Have you ever noticed AI giving a wrong answer with full confidence? 😳
That’s called an AI Hallucination — when an AI model generates information that sounds correct, but is actually false, made-up, or unsupported.

In this video, we break down:
✅ What AI hallucinations really mean
✅ Why AI “confidently lies” even when it’s wrong
✅ Real examples of hallucinations in ChatGPT & other AI tools
✅ How to detect hallucinations and verify AI outputs
✅ Best practices to reduce AI errors in real-world use

Whether you're a student, developer, content creator, or AI enthusiast — this is a must-watch to understand the truth behind AI mistakes.

What are Ai hallucinations?

AI hallucination is a phenomenon wherein a large language model (LLM)—often a generative AI chatbot or computer vision tool—perceives patterns or objects that are nonexistent or imperceptible to human observers, creating outputs that are nonsensical or altogether inaccurate.

Learn about AI hallucinations, their types, why they occur, their potential negative impacts, and how to mitigate them.

AI hallucinations are when a large language model (LLM) perceives patterns or objects that are nonexistent, creating nonsensical or inaccurate outputs.

Understand how AI processes data and generates results and learn to navigate the AI landscape with critical insight to avoid AI's imperfections.

Researchers from the University of Oxford have made a significant advance towards ensuring that information produced by generative artificial intelligence (AI) is robust and reliable. In a new study

Recent data on AI hallucination in healthcare, exploring its occurrence, implications, and strategies to mitigate associated risks.

In February 2025, Google’s AI Overview fooled itself and its users when it cited an April Fool’s satire about “microscopic bees powering computers” as factual in search results (Kidman, 2025). Google did not intend to mislead, yet the system produced a confident falsehood. Such cases mark a shift from misinformation caused by human mistakes to
