Perplexity: Pro Search Failed

Perplexity's Pro Search mode runs a multi-step agentic pipeline: it generates search queries, retrieves results from multiple web sources, synthesizes them, and generates citations. Any failure in that pipeline — search index unavailable, a specific source timing out, or the synthesis model failing — can cause Pro Search to fail. Users on the free tier who run out of Pro Search credits will see Pro Search silently downgrade to Quick Search.
