DeepSeek is a Chinese artificial intelligence research company that develops cutting-edge large language models (LLMs). Founded in July 2023 by Liang Wenfeng and funded by the quantitative hedge fund High-Flyer, the Hangzhou-based firm focuses on achieving artificial general intelligence (AGI) efficiently. It has gained global prominence for matching or rivaling Western frontier AI models while using a fraction of the traditional training and operational costs. [1, 2, 3, 4]
Key Technical Achievements & Models
- DeepSeek-V4: The flagship multimodal LLM series featuring “Pro” and “Flash” variants. It offers a massive 1-million-token context length and utilizes Key-Value (KV) cache compression alongside Sparse Attention mechanisms to slash memory requirements by roughly 90%. [1, 4]
- DeepSeek-R1: A renowned reasoning-focused model trained via massive reinforcement learning (RL). It excels in advanced reasoning patterns like self-reflection and multi-step verification, particularly matching leading industry models in math, STEM fields, and coding. [5, 6]
- Open-Source Distillation: The company openly distributes smaller, highly optimized models (ranging from 1.5B to 70B parameters) distilled from its larger architectures on the DeepSeek Hugging Face repository. [6]
Architecture & Computational Efficiency
DeepSeek bypasses massive computing demands using highly customized infrastructure: [7, 8, 9]
- Mixture-of-Experts (MoE): Utilizes specialized model routing (such as activating only 37B out of 671B total parameters per token in previous iterations) to heavily cut inference workloads. [10]
- Custom Software Kernels: It develops and opens its own optimized infrastructure libraries directly on the DeepSeek GitHub, including custom FP8 matrix multiplication kernels (
DeepGEMM) and communication libraries (DeepEP). [11]
Where to Access DeepSeek
- Web Chat Interface: Users can register and chat directly via the official DeepSeek Chat Platform.
- Mobile Apps: Dedicated applications are available on platforms like the Google Play Store for mobile access.
- Developer API: Software engineers and enterprise businesses can integrate reasoning and chatting pipelines via the DeepSeek Platform API, which is highly favored in the tech sector due to its incredibly low pricing per token. [12, 13, 14, 15, 16]
Would you like to explore how to use its API, look into running a smaller DeepSeek model locally on your computer, or compare its reasoning features with other AI models?
