DeepSeek AI: The Chinese AI That Shocked Silicon Valley
Complete guide to DeepSeek AI, the Chinese lab that built GPT-4 level AI for $6 million. DeepSeek R1, V3, features, and why it matters.
A small Chinese lab built an AI that rivals GPT-4. They did it for $6 million instead of $100 million. And they gave it away for free.
DeepSeek shook the AI world. Here is what it is, why it matters, and how to use it.
What is DeepSeek?
DeepSeek is a Chinese AI research lab that released remarkably capable AI models at a fraction of the cost of Western competitors.
Key achievements:
- DeepSeek R1 matches OpenAI's o1 on reasoning tasks
- Trained for ~$6 million (GPT-4 cost ~$100 million)
- Fully open-source with MIT license
- Free to use with no restrictions
This efficiency shocked the industry. If AI can be built this cheaply, the economics of the entire field change.

DeepSeek Models Explained
DeepSeek-V3 (Chat)
The general-purpose conversational model.
Capabilities:
- General chat and assistance
- Writing and editing
- Translation
- Analysis and research
- Coding help
Comparison: Comparable to GPT-4 for everyday tasks. Good general-purpose AI.
DeepSeek-R1 (Reasoning)
The model that made headlines. Specialized for complex reasoning.
What makes R1 special:
- Trained with reinforcement learning without supervised fine-tuning first
- Self-verification and reflection capabilities
- Long chain-of-thought reasoning
- Matches OpenAI o1 on math, code, and reasoning
Benchmarks:
- 88.1% on AIME-24 math benchmark
- 68.6% on LCB v6 coding tasks
- Competitive with models 7x larger
R1 demonstrates that breakthrough performance does not require massive budgets.
DeepSeek R1-Distill
Smaller, distilled versions of R1's capabilities.
DeepSeek-R1-Distill-Qwen-32B:
- Outperforms OpenAI o1-mini
- State-of-the-art for dense models
- More accessible to run locally
For understanding AI reasoning, see our how AI works guide.
How DeepSeek Achieved This
The technical story matters because it suggests AI development is more accessible than we thought.
Training Efficiency
DeepSeek used:
- Optimized PPO (Proximal Policy Optimization)
- Multi-stage training with intermediate checkpoints
- Knowledge distillation from larger to smaller models
- Efficient use of available compute
Open Source Approach
Everything is public:
- Full model weights
- Training code
- Technical documentation
- MIT license for commercial use
This transparency accelerates the entire field.
The $6 Million Question
For context:
- GPT-4 training: ~$100 million estimated
- DeepSeek R1: ~$6 million
- Factor: ~17x cheaper
This changes who can build frontier AI. Not just OpenAI and Google anymore.
