Perplexity adds optional web grounding to its Decisions API
Perplexity's Decisions API now accepts mode: web_grounding, which runs one Fast Search query per question before pplx-decider-v1.2 returns probabilities. The addition updates the existing hosted decision path; the local Decider for Mac remains a distinct offline option without this hosted search step.
Why it matters: Fresh web evidence can reduce training-cutoff failures in time-sensitive decisions, but it also adds retrieval variability, source quality, latency and an extra billed or rate-limited dependency to a bounded-output workflow.
