Interface: RerankResult<TDocument>#

Defined in: packages/ai/src/types.ts:1818

Public result of the rerank() activity, generic over the caller's document element type so document / rerankedDocuments carry the original values (strings or objects), not their serialized form.

Type Parameters#

TDocument#

TDocument = string

Properties#

id: string;

rerankedDocuments#

rerankedDocuments: TDocument[];

Defined in: packages/ai/src/types.ts:1824

The documents reordered by relevance — ranking.map(r => r.document).

usage#

usage: TokenUsage;

Defined in: packages/ai/src/types.ts:1832

Usage for the request. Rerank typically bills in provider-defined "search units" (usage.billed = { quantity, unit: 'units' }) rather than tokens. Some providers (e.g. OpenRouter) may also report totalTokens and cost. Cohere reports only search units and leaves the token counts at 0. The deprecated unitsBilled field is still populated for compatibility.
