OpenRouter

OpenRouter provides a common interface to multiple AI models, with model information and developer resources for comparing available providers and integrating model access.

It is useful when a question, draft or information task can benefit from an assistant-oriented workflow. Its main areas include AI model access, Model comparison and Developer interface, helping a visitor relate the service to a specific task rather than treating every AI product as an identical kind of tool.

The official OpenRouter site includes sections for Models, Chat and Enterprise.
