OpenRouter

OpenRouter provides access to language models through a common API. It is useful for developers comparing models or building an application that needs more than one provider option.

What you can do

• Unified model API
• Model selection
• Developer access

A useful starting workflow

Use the same evaluation prompts with a few suitable models. Compare the usable result, latency and current billing terms before choosing a default.

What to compare

Check model versions, request formats, response structure and current billing terms. Test failure cases and long-running requests before designing the rest of the product around the API.

Pricing and access

Check the product website for current plans, usage limits and account requirements. The features available in a trial or free account can differ from a paid plan.
