About DeepSeek
DeepSeek is the AI assistant and model family that sent shockwaves through the AI industry in early 2025. Developed by a Chinese hedge-fund-backed research lab, DeepSeek R1 and V3 demonstrated performance rivaling GPT-4o and Claude 3.7 — at a fraction of the training cost.
What makes DeepSeek uniquely compelling is its fully open-source release under the MIT license: anyone can download, self-host, and fine-tune the model without restriction.
Best for: Developers, researchers, cost-conscious teams, anyone comparing Chinese vs Western AI models.
