Frequently Asked Questions
5 questions
Perplexity uses large language models (LLMs) which occasionally 'hallucinate'—generating plausible-sounding but false information. Studies show 5-12% of Perplexity responses contain factual errors. This happens because LLMs predict likely text sequences rather than retrieving verified facts. Always verify critical claims (medical, financial, legal) against primary sources or Google's indexed results. Perplexity does cite sources, but the synthesis itself may misinterpret or combine sources incorrectly.
