DeepSeek, the Chinese outsider in reasoning

DeepSeek was founded in 2023 in Hangzhou, China. In January 2025, its R1 reasoning model surprised everyone with its results and low training cost.

Its models are strong at reasoning and coding. The full versions need a lot of hardware; lighter versions run on more modest machines.

DeepSeek's online app stores personal data in China according to its privacy policy, and several European authorities have restricted it. The usual answer from companies: install the model in-house. That is exactly what Mailpro makes possible.

Good to know with DeepSeek

Avoid the online app for customer data

Installed on your own hardware, DeepSeek sends nothing to its developer; only the calls to Mailpro go out, to your account in Switzerland.

Plan for the hardware

The full versions need powerful servers; start with a light version for testing.

Check the license

DeepSeek's recent models are published under open licenses; check the one for the version you install.

On the Mailpro side, the rules are the same for every assistant: by default, each send waits for your approval, or goes out directly within a daily cap; a log keeps track of everything, and one click suspends all sends. The details.
