Frequently Asked
Did Perplexity cut its Deep Research limits?
Yes, significantly. In early 2026, Deep Research dropped from 500+ runs/day to approximately 20 per month — a reduction of over 99% — while the $20/month price remained unchanged.
Is Perplexity or ChatGPT better for research?
Perplexity for factual, citation-based research — every answer cites live sources and you can choose between GPT, Claude, or Gemini per query. ChatGPT for creative writing, coding, and image generation.
Does Perplexity show usage limits?
Partially — search counts are visible, but the deep cut to Deep Research wasn't clearly surfaced to existing subscribers when it happened. ChatGPT shows no usage meter at all.
Can I use Perplexity's free tier instead of paying?
For light use, yes. The free tier reportedly includes 5–10 Pro Searches/day — sufficient for casual research without a $20/month subscription.
