FAQ

Questions about Rerank.

What does the Rerank action do in Voyage AI?

Reranks a list of candidate documents against a query, returning relevance scores. Standard last-mile step after vector retrieval to boost RAG precision before feeding context to the LLM.

What inputs does Rerank require?

Required: Model, Query, Documents. Every input accepts a static value or a variable from any upstream node in your workflow.

Can I use dynamic inputs from earlier workflow nodes?

Yes. Any field on this action can pull values from upstream nodes, whether that's a form response, a trigger payload, an AI output, or a lookup result.

What happens if Voyage AI returns an error?

The workflow pauses on the failed node, the error message is captured in the run log, and you can retry the run with one click. Auto-retry policies are configurable per workflow with exponential backoff up to 5 attempts.

Does Rerank support batch operations?

Yes. Run Rerank inside a Loop node to process arrays. Tiny Command handles Voyage AI's rate limits automatically so you don't have to throttle manually.
