Eye-opening to see some non-coding LLM applications regress over the last year in functionality. I used to trust Perplexity as an AI search engine as it summarizes underlying sources, and did it well. It now hallucinates stuff despite crawling pages with correct information. Eg I asked it where Jamie Vardy (Leicester City hero / footballer) is playing. Perplexity says as of May 2026 there’s no information… despite crawling sources that confirm he’s been playing in Italy
