01 · What it's good at

Use it for this.

Three jobs this model is built for, and the ones to give to something else.

01

The last step of retrieval, after a vector search

Skip it for

  • Generating the answer or the embedding

02 · Example tasks

What you'd actually send it.

Real inputs, not a benchmark. Paste one into the snippet below to try it.

You send

Rerank 50 vector hits to the top 5.

Why this model

Better passages, better answers.

03 · Your stack

Where it sits: Retrieve.

A reranker scores query-plus-passage pairs and returns an order. It is how RAG stops citing the wrong chunk.

04 · Wire it up

One request. Paste and run.

Uses OpenRouter, so one key works for every model on this site. Set OPENROUTER_API_KEY and swap the prompt for one of the tasks above.

const res = await fetch("https://openrouter.ai/api/v1/rerank", {
  method: "POST",
  headers: {
    Authorization: `Bearer ${process.env.OPENROUTER_API_KEY}`,
    "Content-Type": "application/json",
  },
  body: JSON.stringify({
    "model": "nvidia/llama-nemotron-rerank-vl-1b-v2:free",
    "query": "Can I pay annually?",
    "documents": [
      "Billing runs monthly.",
      "Annual plans are billed once a year."
    ],
    "top_n": 2
  }),
});
const { results } = await res.json();
for (const r of results) console.log(r.relevance_score.toFixed(3), r.document.text);
