What is DeepSeek?

DeepSeek is the Chinese AI lab that shocked the industry with cost-efficient, high-performance models. The 2026 V4 and V4-Pro models compete with GPT-5 class performance at a fraction of the cost. In April 2026, DeepSeek announced a 75% price cut on V4-Pro API access, making it the most affordable frontier AI for developers. The free web interface includes file upload, long context, and code execution.
