About OpenRouter
Overview
OpenRouter is the unified interface for every AI model, giving developers a single, OpenAI-compatible API for 500+ models across 80+ providers. The platform generates text, images, videos, and audio in one place, and charges pay-as-you-go credits instead of subscriptions.
OpenRouter reports 300T+ monthly tokens, 10M+ global users, and 250k+ apps running on the platform, with featured agents including Replit, Hermes Agent, and Kilo Code. Founded in early 2023 as the first LLM marketplace, it has raised $113 million from investors including an Alphabet investment arm.
Key Benefits
- Access 500+ models from 80+ providers through a single unified API
- Fall back automatically to other providers when one provider goes down
- Pay as you go with credits that work with any model or provider
- Run at the edge to minimize latency between your users and inference
- Enforce fine-grained data policies so prompts only go to models and providers you trust
- Compare model prices and performance to fit each prompt's budget and latency needs
How It Works
Sign up for a free account, then optionally create an org for your team. Buy credits that work with any model or provider, create an API key, and start making fully OpenAI-compatible requests. OpenRouter routes each request across its provider network, falls back automatically when a provider fails, and tracks response times and error rates in real time.
Use Cases
- Indie hackers ship AI features with no subscription and no minimum spend
- AI-native startups choose the cheapest model for each task through price comparison
- Enterprises set data policies so prompts only reach approved models and providers
- Developers build agentic apps such as Replit, Hermes Agent, and Kilo Code on the API
- Teams keep requests flowing through automatic failover when providers go down
- Enterprises use admin controls for SSO, invoicing, and dedicated rate limits
