DeepSeek V4 Pro got cheaper for Enterprises requiring ZDR

I am managing the AI coding architecture in an Enterprise envionment and am also responsible for selecting available providers/models to our developers. Since our company requires all endpoints to be ZDR (Zero Data Retention), direct access to DeepSeek in China was never an option. Instead we are using third-party inference providers with ZDR per contract. They are located in USA and EU. This providers charged roughly $1.74 / $3.48 / $0.15 (input, output, cached-input) for the "old" DeepSeek V4 Pro. Now with deepseek-v4-pro-0813, this providers seem to adapt the Peak-Hour pricing from DeepSeek directly. $1.32 / $3.96 / $0.04 Especially the $0.04 cache-read, which is responsible for 80-90% of the effective costs, is a huge cost saver for a company like us.
