What AI hallucinations are in AI for Everyone - Step-by-Step Execution

Concept Flow - What AI hallucinations are

User asks AI a question

↓

AI processes input

↓

AI generates answer

↓

Is answer based on real data?

No→AI hallucinates (makes up info)

Yes↓

AI provides correct info

This flow shows how AI can either provide correct answers or hallucinate by making up information when unsure.

Execution Sample

AI for Everyone

User: "Who won the 2025 World Cup?"
AI: "The 2025 World Cup was won by Atlantis FC."

The AI answers a question about a future event with made-up information, illustrating hallucination.

Analysis Table

Step	Action	Input	AI Processing	Output	Hallucination?
1	Receive question	Who won the 2025 World Cup?	Analyze question context	N/A	No
2	Search knowledge	Check training data	No info on 2025 World Cup	N/A	No
3	Generate answer	No real data found	Predict plausible answer	"Atlantis FC won the 2025 World Cup."	Yes
4	Output answer	Provide response	Deliver generated text	"Atlantis FC won the 2025 World Cup."	Yes
5	End	Conversation continues	N/A	N/A	N/A

💡 AI stops after generating an answer, even if it is hallucinated due to lack of real data.

Key Insights - 2 Insights

Why does the AI sometimes give answers that sound real but are actually made up?

When the AI cannot find real data in its training, it predicts an answer based on patterns, which can lead to hallucinations as shown in step 3 of the execution_table.

Is AI always aware when it hallucinates?

No, the AI does not know it is hallucinating; it simply generates the most plausible answer it can, as seen by the hallucination flag turning true only after answer generation.

Visual Quiz - 3 Questions

Look at the execution_table at step 3. What does the AI do when it finds no real data?

A It asks the user for more info.

B It refuses to answer.

C It makes up a plausible answer.

D It searches the internet.

💡 Hint

Check the 'AI Processing' and 'Output' columns at step 3 in the execution_table.

According to variable_tracker, when does the hallucination flag become true?

A After receiving the question.

B After generating the answer.

C Before analyzing the question.

D At the start.

💡 Hint

Look at the 'Hallucination Flag' row and see when it changes from False to True.

If the AI had real data about the 2025 World Cup, how would the execution_table change at step 3?

A It would generate a correct answer based on real data.

B It would generate a hallucinated answer anyway.

C It would refuse to answer.

D It would ask the user to rephrase.

💡 Hint

Refer to the 'Hallucination?' column and the 'Knowledge Found' variable in variable_tracker.

Concept Snapshot

AI Hallucinations:
- Occur when AI lacks real data.
- AI predicts plausible but false info.
- Happens silently without AI awareness.
- Can mislead users if unchecked.
- Important to verify AI answers with trusted sources.

Full Transcript

AI hallucinations happen when an AI system tries to answer a question but does not have real information in its training data. Instead of saying 'I don't know,' it guesses an answer that sounds plausible but is actually made up. This process starts when the AI receives a question, checks its knowledge, finds no real data, and then generates a predicted answer. The hallucination flag turns true after answer generation, meaning the AI is not aware it is making up information. Users should be careful and verify AI answers, especially for unknown or future topics.
