Perplexity adds live web searches to Decisions API for real-time answers
Perplexity launched live web grounding in its Decisions API on November 4, 2026, letting developers fetch real-time data before the model returns structured probabilities. The feature searches up to 10 URLs per question—limited to one second per search—before appending results as evidence. It targets dynamic decisions like executive roles, software updates, or event statuses, where answers may…
Key points
- Live web grounding fetches up to 10 URLs per question before model answers, adding real-time evidence to probability outputs
- Perplexity reports 97.3% accuracy on 328 claims with grounding, up from 56.4%, but latency rises to 366 ms median
- Searches cost $0.001 each, capped at $0.10 for 100 questions, with retrieved data counted toward token limits
Perplexity claims accuracy jumped from 56.4% to 97.3% on 328 true/false claims when using live grounding, though latency nearly tripled (median 366 ms vs. 139 ms). On Parallel Web Systems’ benchmark, the grounded model achieved 86% accuracy on 100 public questions, surpassing its own previous score. Searches cost $0.001 each, with a $0.10 cap for 100 questions, but retrieved evidence also counts toward token limits. The API supports Python 0.44.0+ and TypeScript 0.39.0+, though type definitions for search results are still pending.
