Perplexity adds optional live web grounding to its Decisions API, available immediately

Perplexity announced on November 4, 2026 that web grounding is available immediately for its Decisions API, adding optional live web searches before the model returns probabilities, according to Unite.AI.

What changed

The new feature targets decisions whose answers can change after a model's training. Examples cited include:

• A person's executive role
• A software package's latest release
• Whether an event remains scheduled

How the Decisions API works

The Decisions API accepts content as state and returns structured numeric answers instead of prose. Web grounding is optional, so live searches run before the model returns its probabilities only when the feature is used.

Pricing, supported models, context window size and benchmark results were not part of the information available at the time of writing.

What this means

Answers about executive roles, package releases and event status can go stale after training. Web grounding gives the Decisions API a way to check current information before it returns a probability, rather than relying only on what the model learned. Because the feature is optional, developers can decide per use whether a decision needs live data. Because the API returns structured numeric output rather than prose, grounded results fit directly into systems that consume probabilities.
