How to Reduce AI Hallucinations with AI
1
Ask the AI to only state what it is confident about and flag uncertainties explicitly
2
Provide context and source material rather than asking from general knowledge alone
3
Request citations or evidence for factual claims in the response
4
Cross-reference important facts by asking the same question to a second AI model
5
Use Perplexity for fact-dependent questions since it grounds answers in web sources
6
Ask the AI to think step-by-step rather than jumping to conclusions
