OpenRouter

OpenRouter is a single front door to more than 500 AI models from over 80 providers, including OpenAI, Anthropic, Google, DeepSeek, Qwen and dozens of open models. You load credit once, get one API key, and can then call any of them. Token prices are passed through at each provider's list price, and OpenRouter takes a 5.5% fee when you buy credits. It also has a simple chat room on the website for trying models side by side.

Use it when you are building an AI feature into a product or internal tool and don't want to sign up, bill and code against five different AI companies. It can fall back to another provider when one goes down, route requests by price or speed, and cap spending per key. It is also the cheapest way to try a new model the day it launches, and some models are free. If you only ever use one model, going direct to that company is simpler.

The catch is that the same open model can behave differently depending on which provider OpenRouter sends you to; some hosts are slower, cut corners on tool use or quietly return empty answers. Free models are rate limited and often busy. Unused credit can expire after a year, refunds are only offered within 24 hours of a purchase, and Stripe has agreed to buy the company (August 2026, still awaiting approval).

• Developers
• SaaS founders
• AI app builders
• Agencies
• Hobbyists

Business owners and developers adding AI to a product, and anyone who wants to try lots of models cheaply from one account.

• 500-plus models, one API

  Call OpenAI, Anthropic, Google, DeepSeek, Qwen, Mistral and many open models with the same code and key.

• Automatic fallback

  If a provider is down or rate limited, the request moves to another host of the same model so your app keeps working.

• Auto Router

  Let OpenRouter pick a model for each prompt, with cost tiers from low to max and no extra fee.

• Budgets and spend controls

  Set limits per API key or workspace so a runaway script or agent can't burn through your credit.

• Privacy routing

  Prompts aren't logged by default, and you can block providers that train on or retain your data.

• Chat room

  Try models side by side in the browser before you write any code. Chats stay on your device.

Ways OpenRouter can slot into your week.

1. 1

   Add AI to a product without lock-in

   Build your chatbot, summariser or quote writer against OpenRouter, then switch models later as prices drop without rewriting anything.

2. 2

   Cut the AI bill on bulk jobs

   Send repetitive work like tagging, translating or summarising to a cheap open model, and keep the expensive one for the hard calls.

3. 3

   Test a new model the day it lands

   New releases, and some free preview models, appear on OpenRouter within hours. Try them on your real prompts before committing.

4. 4

   Keep your app up during outages

   Fallbacks route around a provider that is down, so customers don't see errors when one AI company has a bad day.

5. 5

   Give coding tools more models

   Plug an OpenRouter key into tools like Cline, OpenCode or Copilot to use models those tools don't offer by default.

It sits between your app or automation and the AI companies. Most AI tools that accept an OpenAI-style API key can point at OpenRouter instead, so it slots into n8n, Make, coding agents and custom apps without much work.
