Free OpenRouter models & credits

OpenRouter gives you one API to reach hundreds of models, including a rotating set of free ‘:free’ variants you can call with no credit card.

The short answer

With OpenRouter’s free models you get 50 requests/day (20/minute) at no cost and no card. A one-time $10 credit purchase lifts the daily cap to 1,000 free-model requests — useful once you move past prototyping.
