What is DeepSeek?
DeepSeek is a Chinese AI research lab whose open-weight models DeepSeek-V3 and DeepSeek-R1 rivaled GPT-4 on coding and math benchmarks at a fraction of the training cost, shaking the AI industry when they debuted in late 2024 and early 2025.
The R1 model introduced chain-of-thought reasoning that users can watch unfold step by step, making it particularly powerful for complex logic and problem-solving.
DeepSeek's chat interface at deepseek.com is free to use and gives access to both the standard V3 model and the reasoning-focused R1 model. For developers, the API is priced significantly below GPT-4 equivalents, making it an attractive choice for high-volume production workloads where cost efficiency matters as much as quality.
The open-weight nature of DeepSeek's models means companies can self-host them on their own infrastructure removing data privacy concerns and enabling fine-tuning on proprietary datasets. This combination of benchmark-competitive performance, low API cost, and true open weights has made DeepSeek the fastest-adopted AI model family of 2025.
