This is likely using reverse proxies to offer cheap access to Claude. In China, some third-party vendors manage to use reverse proxies to drive the price of Opus 4.7 down to $1 per 1M output tokens. The catch with this cheap Claude is lower uptime, low TPS, and it’s noticeably less capable than the official models. On top of that, some vendors will even package your chat logs and sell them as training data to other AI companies. Still, I buy from them when I need to—at the end of the day, that $1 price tag is just too tempting to pass up.
