DeepSeek
DeepSeek is a Chinese AI lab whose open models, such as R1, deliver powerful performance at a fraction of typical API prices.
DeepSeek is an AI lab from Hangzhou that shook up the industry in early 2025 with its R1 reasoning model: performance close to GPT-level, released with open weights, and trained at a fraction of the usual cost.
It's relevant for you in two scenarios: as a free chat assistant for research, math, and code, or as an API for your own applications on a tight budget. Its strength lies in its price-performance ratio; R1, with its 671 billion parameters, is freely available under an MIT license.
Compared to Claude or ChatGPT, DeepSeek falls short in German quality and polish. The bigger catch: the official chat app processes data on servers in China and blocks politically sensitive topics. For corporate data, realistically, only a self-hosted version or a European host is an option.
Right for developers and tech-savvy teams who want to run open models affordably. Wrong for anyone who would feed sensitive data into the official app; in that case, Claude, ChatGPT, or Mistral are the cleaner choice.
