DeepSeek vs Open WebUI

TL;DR: DeepSeek is an AI model provider offering high-performance reasoning capabilities at low cost, while Open WebUI is a self-hosted interface that lets you connect to and manage any AI model including DeepSeek. Choose DeepSeek if you want a specific powerful model with minimal setup, or Open WebUI if you need infrastructure to run multiple models locally with full control over your data and deployment. They're complementary rather than direct competitors—you could actually use DeepSeek's API through Open WebUI's interface.
