How do I rerank RAG candidates with Cohere?

Short answer: You can rerank in Cohere by hand from its own interface, but it won’t repeat itself. On TinyCommand, add the Cohere Rerank action to a workflow, map its 4 inputs from any upstream app, and it runs automatically every time the trigger fires. No code, and a free tier to start.

Inputs

The fields this action accepts.

Every field can be mapped from an upstream trigger, AI step, table row, or hard-coded literal.

Field	Type	Required	Description
Query query	string	Required	The search query to rank documents against
Documents (JSON array) documents	array	Required	Array of text strings to rerank
Model model	options	Optional	Model. Options: Rerank v3.5 (latest), Rerank English v3, Rerank Multilingual v3
Top N top_n	string	Optional	Number of most relevant documents to return

Sample request

{
  "query": "e.g. What is the refund policy?",
  "documents": "{{trigger.documents}}",
  "model": "{{trigger.model}}",
  "top_n": "e.g. 3"
}

Returns

{
  "results": [
    {
      "index": 2,
      "document": {
        "text": "Returns accepted within 30 days..."
      },
      "relevance_score": 0.98
    },
    {
      "index": 0,
      "document": {
        "text": "Our refund policy allows..."
      },
      "relevance_score": 0.85
    }
  ]
}

Use these fields in downstream nodes for routing, logging, or error handling.

FAQ

Questions about Rerank.

What does the Rerank action do in Cohere?

Reranks a list of documents by relevance to a query using Cohere's Rerank model. Essential last-mile step in any serious RAG pipeline; meaningfully lifts precision over vector-only retrieval.

What inputs does Rerank require?

Required: Query, Documents (JSON array). 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 Cohere returns an error?

The run history shows the failed step with its input and the error message Cohere returned, so you can fix the input and run the workflow again. Automatic retries are built into HTTP steps only, where you can also set your own retry count and delay.

Does Rerank support batch operations?

Run Rerank inside a loop to process each item in an array. TinyCommand does not throttle calls for you, so for large arrays add a Delay step if you need to stay within Cohere's rate limits.

Chat with Tools

Chats with Cohere Command models with tool/function calling enabled. Use to let the model fetch data, run actions, or build agents within Cohere's ecosystem.

Action

Create Embeddings

Generates vector embeddings for text using Cohere's embed-v3 model. Supports input_type (search_document, search_query, classification, clustering), which materially improves retrieval quality, so set it correctly.
