Best-fit workloads

Best for long context

Large context window for documents and transcripts.

Best for budget

Low input/output cost for high-volume workloads.

Cost estimates

These examples use the 2026-10-16 input and output prices. Cache discounts, provider surcharges and tool fees are excluded.

Workload	Input	Output	Estimated cost
Quick test	20,000	5,000	$0.001
Product chat month	500,000	125,000	$0.020
Document batch	5,000,000	1,000,000	$0.200

Strengths

✓ Output is billed at $0: $0.04 per million input tokens and nothing per output token
✓ A 1,000,000-token window, and a 4,000-token answer — summarisation by construction
✓ Abstractive rewrites rather than sentence lifting, which is the difference that matters when the summary is shown to someone

Limitations

! The 4,000-token output ceiling is a product decision, not a limit you can raise
! No published benchmark, and Artificial Analysis does not carry it
! Same caveat as its sibling: with no output price, it cannot sit in an output-price comparison

OpenRouter API quickstart

Run these examples from your server or edge function. Keep the OpenRouter API key private and do not expose it in browser code.

JavaScript / TypeScript

const response = await fetch("https://openrouter.ai/api/v1/chat/completions", {
  method: "POST",
  headers: {
    Authorization: `Bearer ${process.env.OPENROUTER_API_KEY}`,

const data = await response.json();
console.log(data.choices[0].message.content);
