What is DeepSeek? Platform Overview
DeepSeek launched from Hangzhou DeepSeek Artificial Intelligence Basic Technology Research Co., Ltd. The company was founded in July 2023. It performs advanced natural language processing through cutting-edge models.
Text-based tasks achieve remarkable accuracy. Within two years, DeepSeek became a global competitor. It now challenges OpenAI and Google directly.
Liang Wenfeng founded the company after co-founding High-Flyer hedge fund. High-Flyer holds approximately $8 billion in value. Unlike most startups, DeepSeek funds itself entirely.
No venture capital investors influence company decisions. This independence allows focus on long-term research goals. Short-term profitability pressure doesn’t affect development direction.
The flagship models pack 685 billion parameters. They rank among the largest language models available. Everything ships under the MIT License. Developers can use, modify, and deploy models commercially.
No restrictions apply. The open-source community exceeds 500,000 developers. Stanford University incorporates DeepSeek architecture into research programs.
History and Development Timeline
DeepSeek’s rapid evolution provides context for current capabilities. The company achieved remarkable milestones quickly. Understanding this history reveals future direction potential.
2023: Foundation Year
High-Flyer announced plans for a research lab in April 2023. By July 17, the lab became independent. It took the name DeepSeek. The team released DeepSeek Coder on November 2, 2023. DeepSeek-LLM series followed on November 29. Both targeted different user segments effectively.
2024: Rapid Advancement
January 2024 brought DeepSeek-MoE models. These featured Mixture of Experts architecture. Cost efficiency advantages emerged from this design. DeepSeek-V2 launched in May with capability improvements. DeepSeek-Coder V2 followed in June. V2.5 arrived in September with reasoning enhancements.
2025: Global Recognition
January 2025 changed everything for the company. The R1 model launched alongside mobile applications. By January 27, DeepSeek topped US iOS App Store rankings.
It became the first Chinese app achieving this prominence. Nvidia shares dropped 18% immediately. Investors worried about reduced chip demand.
The R1 model proved something important. Frontier systems could be built cheaply. OpenAI spent around $100 million training GPT-4. DeepSeek claims V3 cost just $5.576 million.
It used one-tenth the computing power. March 2025 delivered V3-0324. August brought V3.1. December saw V3.2 and V3.2-Speciale releases.

Model Families Explained
DeepSeek offers two primary model families. Each optimizes for different use cases. Understanding distinctions helps select the right tool.
V3 Series: Conversational Excellence
The V3 series excels at conversation and creative writing. General-purpose applications benefit from speed and fluency. V3.2 introduces groundbreaking features rivaling industry leaders. Cost efficiency remains a distinguishing factor. Users report satisfaction across diverse task types.
Key capabilities include 128,000 token context windows. Analyze lengthy documents in one session. Entire codebases fit within context limits. Choose thinking mode for deep reasoning.
Choose non-thinking mode for rapid responses. Sparse Attention cuts inference costs by 50-75%. Output quality remains unchanged.
V3.2-Speciale represents peak reasoning capability. It earned gold at 2025 International Mathematical Olympiad. It won at International Olympiad in Informatics. ICPC World Finals gold came too. At IMO, it scored 35 of 42 points. No internet or tools were used during testing.
R1 Series: Advanced Reasoning
The R1 series focuses on logical inference. Mathematical reasoning and problem-solving shine here. Transparency matters as much as accuracy. Released January 2025, R1 matched OpenAI’s o1 model. On many benchmarks, R1 exceeded o1 performance.
R1 displays step-by-step reasoning before answering. Educators find this particularly valuable. Analysts appreciate seeing the logic unfold. The model achieved 96.3% on AIME 2024.
OpenAI o1 scored only 79.2%. Smaller distilled versions run on consumer hardware. R1-Distill-Qwen-7B scored 55.5% on AIME 2024.

Technical Architecture and Innovations
Impressive performance stems from technical innovations. Both capability and efficiency benefit from these advances.
Mixture of Experts (MoE) Architecture
DeepSeek distributes loads across specialized modules. Not all 685 billion parameters activate per query. The system engages only relevant portions selectively.
Efficiency improves dramatically through this approach. Frontier-level performance requires fewer computational resources. DeepSeek matches competitors using cheaper hardware.
DeepSeek Sparse Attention (DSA)
DSA represents a breakthrough in long-context processing. Traditional attention mechanisms scale poorly. Doubling input typically quadruples computation requirements.
DSA uses a “lightning indexer” instead. It identifies only relevant context portions. Inference costs drop approximately 50%. Analyzing 300-page documents becomes economically viable.
Thinking in Tool-Use
V3.2 integrates reasoning into tool utilization directly. Long-chain reasoning happens before calling tools. Complex multi-step tasks improve significantly. Users benefit from reliable automation workflows. Errors reduce in multi-tool scenarios.
Pricing Structure and Plans
Flexible pricing serves various user types. Casual experimenters and enterprises both find options.
