@juspay/neurolink/dist/providers/perplexityDecider.d.ts

The pipe layer of an AI nervous system: one interface connecting provider neurons to your application, across three inference types — generate, stream and decide. `decide` returns typed, calibrated judgements from a non-generative model (~400ms, ~$0.00002

import type { DecisionError, DecisionPreparedMedia, DecisionState, NeurolinkCredentials } from "../types/index.js";
import { SystemOneDecisionProvider } from "./systemOneDecision.js";
/**
 * Perplexity Provider — the `decide` inference type only.
 *
 * `pplx-decider-v1-27b` answers the same typed `noul` / `choice` / `score`
 * questions as the other decision providers, in one batched pass, and also reads
 * images. It is a hosted API with a public endpoint, so unlike the self-hosted
 * providers it needs only a key. The request loop, retries, auth circuit
 * breaker and answer parsing are shared with every decision provider in
 * {@link SystemOneDecisionProvider}.
 *
 * The key is the same `PERPLEXITY_API_KEY` the Sonar text provider reads, so a
 * host that has configured that provider has also configured this one.
 *
 * @see https://docs.perplexity.ai/api-reference/decisions-post
