OpenRouter: artificial intelligence features and setup
A unified interface for accessing and comparing prices across many language models.
Tool by the Otomatzia editorial team · source content checked on
Overview
OpenRouter suits teams that want one interface for multiple model providers instead of connecting to each provider separately. Send a request in a unified format, choose a model, and compare costs across options. It is a gateway to models, not a complete agent-building tool. Before operational use, decide which models are allowed, what to do when a model fails, and which data passes through the gateway.
Features
- Unified interface for calling different language models
- Price comparison across supported models
- Request routing without connecting to each provider separately
Business uses
- Switching an experimental model for another without rewriting the entire integration
- Comparing the response cost of two models on the same classification task
Getting started
- Connect a test key and send one request to a low-cost model.
- Compare the same question with a second model and check for differences in the output.
- Define an allowlist of models before connecting to a live environment.
What to check
- The gateway can see request content. Check its retention policy before sending customer data.
- A lower-cost model may fail to produce the output format the workflow expects.
