OpenRouter, explained simply
OpenRouter is a middleman for AI models. You sign up once and can use models from many different companies.
It matters because you can switch models without making a new account each time. It is handy for comparing them.
For example, a tool asks for an API key. You paste in your OpenRouter key and choose any model on the list.
You pay for what you use, and some models are offered free with limits.
On ITG Now, our free tool guides mention OpenRouter when a project lets you pick from many models with one key.
