OpenRouter models
OpenRouter's own entries are ROUTERS, not models: each one reads the request and forwards it to whichever underlying model fits best, so its price and capabilities depend on where it lands. Zeplik carries the Auto Router and its beta, the Fusion and Pareto Code routers, and the free-models router.
All 6 OpenRouter models
The experimental version of our Auto Router where we test new improvements.
Fusion turns your prompt into a small multi-model deliberation.
The Pareto Router maintains a tiered shortlist of strong coding models, ranked by [Artificial Analysis](https://artificialanalysis.ai/) coding percentiles.
The simplest way to get free inference. openrouter/free is a router that selects free models at random from the models available on OpenRouter.
Transform your natural language requests into structured OpenRouter API request objects. Describe what you want to accomplish with AI models, and Body Builder will construct the appropriate API calls.
The Auto Router automatically selects the best model for your prompt, powered by the wisdom of the market.
