OpenRouter offers 21 free models, with a dynamic router handling roster churn

By PulseAugur Editorial · [1 sources] ·

OpenRouter's API provides access to a large number of models, with a subset designated as free. While filtering by a ':free' suffix initially suggests 18 free models, a deeper analysis reveals 21 models with zero pricing for both prompt and completion. Three models, including 'openrouter/free', are missed by the suffix filter. The 'openrouter/free' model acts as a router, dynamically selecting an available free model for users and handling the frequent changes in the free model roster, which can quickly make hardcoded free model IDs obsolete. AI

IMPACT Simplifies access to free LLM inference by abstracting away model roster changes.
