FAQ
Requests to Claude/GPT/Gemini go to their official APIs. Requests to Chinese models (DeepSeek, Qwen, GLM, Kimi) are routed to providers in mainland China — if your compliance rules forbid that, use the flagship models only. We log usage for billing, never store your prompts for training.
Claude/GPT/Gemini 请求走官方API；中国模型（DeepSeek/Qwen/GLM/Kimi）请求会路由到 中国大陆的服务商——如你有合规限制请只使用旗舰模型。我们仅为计费记录用量，不存储、 不训练你的prompt内容。
Three things: payment methods that work outside the US card system (USDT from $5), deeper coverage of Chinese models, and bilingual human support. If OpenRouter already works for you, it's a fine product — we exist for the people it doesn't serve.
三点：不依赖国际信用卡的支付方式（USDT，$5起）、更全的中国模型覆盖、中英双语真人支持。 如果OpenRouter已经满足你，它是个好产品——我们服务的是它照顾不到的人。
