OpenRouter
Route requests to 200+ LLMs from a single API key. Swap models, run fallbacks, and compare costs across every major provider without rewriting your integration.
The verdict on OpenRouter: Developers who want to compare or switch between 200+ models from every major provider through one endpoint OpenRouter's actual value isn't access to 200-plus models, it's the ability to swap providers with a one-line config change using an OpenAI-compatible SDK, so you never have to rewrite integration code to test a different model or avoid an outage. Pricing: Limited free-model access / Model-specific pay-as-you-go pricing; separate platform fee applies.
Best For
Developers who want to compare or switch between 200+ models from every major provider through one endpoint
Standout Feature
Model-specific pay-as-you-go pricing and automatic fallback when a model is down; separate platform fee applies
TL;DR
The simplest way to avoid being locked into one provider, it adds a network hop versus calling a provider directly.

Overview
Not yet reviewedProduct quality is assessed from original evidence. How reviews work.
OpenRouter provides a unified API gateway to 200+ language models from every major provider, OpenAI, Anthropic, Google, Meta, Mistral, and dozens more, through a single OpenAI-compatible endpoint. Swap models with a one-line change, run automatic fallbacks when a model is unavailable, and compare costs across providers in real time. Limited access to free models is available; paid models use model-specific pay-as-you-go rates, with a separate platform fee. Free-model access is not a general credit offer for paid models.

Trust & Data
Verified 2026-09
- Training on your data
- NoOpenRouter itself does not train on user inputs and has opted out of model training with upstream providers where possible, but explicitly disclaims responsibility for individual third-party model providers' own training practices, which vary by the model selected.
- Compliance
- SOC 2 Type 2
- Retention
- Image, audio, and video inputs are not persisted beyond routing the request except for abuse detection, security, billing, or legal compliance; files uploaded via the Files API are retained until the user deletes them or closes the account.

Our Take
Model-specific pricing and automatic fallback routing are the features that matter in production; factor the separate platform fee into costs. The tradeoff is a network hop added versus calling a provider directly, which adds some latency. Limited free-model access lets you test the gateway; paid models require model-specific pay-as-you-go billing. For developers who want to avoid being locked into a single provider and need fallback reliability, this is the cleanest routing layer available.
