## The use case: how Pax Historia deploys OpenRouter

Pax Historia is an alternate-history sandbox game where AI models decide how countries react to player actions. It uses OpenRouter to offer players a choice of many AI models from multiple providers through a single integration, with automatic fallback if a provider goes down.

Summary written by usedby from the source page, in English. The figures are those of OpenRouter and Pax Historia, not ours.

> Today, Pax Historia routes through 7+ AI providers via OpenRouter. They've routed 4.87 million requests through OpenRouter over the last month alone.

- **4.87 million**: “They've routed 4.87 million requests through OpenRouter over the last month alone.”
- **28+**: “Players are then able to pick from 28+ AI models to optimize the kind of quality and pricepoint they want to play at.”
- **7+**: “Today, Pax Historia routes through 7+ AI providers via OpenRouter.”

> Stealth models are a game-changer for us — our players get access to the newest models the moment they drop, with minimal developer burden. And the provider fallback means if one provider hiccups at 2 AM, the game just keeps running.
