OpenRouter GA: US in-region routing for Chinese open-weight models
OpenRouter’s US In-Region Routing is generally available for Business/Enterprise: requests to us.openrouter.ai stay decrypted and served only in the US (or 404). Open-weight models are ~60% of its US tokens, mostly Chinese (DeepSeek V4 Pro, Kimi K3, GLM 5.2 via US hosts).
