OpenRouter launches US in-region routing, keeping decryption and inference inside the country

OpenRouter 推出美国区域路由，与去年上线的 EU 路由配套保障数据驻留

OpenRouter added a US in-region routing endpoint (us.openrouter.ai) for Business and Enterprise plans, matching the EU routing launched last October. Requests are decrypted and served only by US-based providers; if no in-region endpoint exists, the call fails with a 404 instead of falling back outside the region. Chinese open-weight models like DeepSeek V4 Pro, Kimi K3, and GLM 5.2 are available through US routing because Baseten, Fireworks, and Azure host them in US data centers. The post also flags that many gateways only pin inference to a region while decrypting traffic elsewhere—OpenRouter locks the full path inside the chosen region.
