DeepSeek: A Game Changer in AI Development
In the fast-evolving field of artificial intelligence (AI), it has long been believed that creating advanced large language models (LLMs) requires substantial financial and technical resources. This belief contributed to the U.S. government’s commitment to supporting the $500 billion Stargate Project, initiated by President Donald Trump. However, this narrative has changed significantly with the emergence of the Chinese AI company DeepSeek.
What is DeepSeek?
Founded in May 2023 by Liang Wenfeng, an alumnus of Zhejiang University, DeepSeek is based in Hangzhou, China. The company operates under High-Flyer, a quantitative hedge fund that co-owns DeepSeek. While specific details regarding its funding and overall valuation remain undisclosed, the focus of DeepSeek lies in the development of open source LLMs.
DeepSeek’s foray into the market began with the release of its initial model in November 2023, followed by rapid iterations leading to its breakout product, the R1 reasoning model, in January 2025. The R1 model’s launch sparked a significant surge in popularity, along with a companion mobile app that quickly climbed to the top spot on the Apple App Store, surpassing OpenAI’s ChatGPT.
Key Features of DeepSeek
- Open Source Models: DeepSeek offers its LLMs under an open-source license, promoting accessibility and usability.
- Multiple Services: The company provides a web interface, mobile applications, and API access for its models.
- Innovative Training Techniques: DeepSeek employs distinct training methodologies that differentiate it from its competitors.
DeepSeek vs. OpenAI
As DeepSeek emerges as a competitor to OpenAI, it brings a different set of strategies to the table. OpenAI has been a leader in the generative AI space since launching ChatGPT in 2022, but DeepSeek’s entry has created notable comparisons.

| API Pricing (per million tokens) | o1: $15 (input), $60 (output) | DeepSeek-R1: $0.55 (input), $2.19 (output) |
| Open Source Policy | Limited | Mostly open source |
| Training Approach | Supervised & instruction-based | Reinforcement learning |
| Development Cost | Hundreds of millions | Less than $6 million |
Innovations in DeepSeek’s Training
DeepSeek takes pride in its innovative training methods for the R1 model, which allow for reduced development time, lower costs, and fewer AI accelerators. The company’s commitment to achieving artificial general intelligence is evident in its advancements in reasoning capabilities. Key innovations include:
- Reinforcement Learning: Focused on reasoning tasks.
- Reward Engineering: A rule-based system that enhances model performance.
- Knowledge Distillation: Using efficient techniques to condense capabilities into smaller models.
- Emergent Behavior Networks: Discovering complex reasoning patterns through reinforcement learning, without the need for explicit programming.
DeepSeek’s Range of LLMs
Since its inception, DeepSeek has rolled out various generative AI models, each marked by improvements in capabilities:
- DeepSeek Coder: Launched in November 2023, tailored for coding tasks.
- DeepSeek LLM: The initial version released in December 2023 for general purposes.
- DeepSeek-V2: Released in May 2024 with enhanced performance.
- DeepSeek-Coder-V2: A 236 billion-parameter model aimed at complex coding issues.
- DeepSeek-V3: Introduced in December 2024, utilizing a mixture-of-experts architecture.
- DeepSeek-R1: Released in January 2025, focusing on reasoning tasks and competitive with OpenAI’s offerings.
- Janus-Pro-7B: A vision model capable of understanding images, launched in January 2025.
U.S. Concerns Over DeepSeek
DeepSeek’s rise has caused concern in the U.S., particularly among investors who have begun questioning the viability of American tech firms like Nvidia and Microsoft. Key reasons for these apprehensions are:
- Cost Disruption: DeepSeek claims its R1 model was developed for under $6 million, posing a threat to U.S. companies that have invested heavily in AI.
- Technical Achievements Despite Restrictions: DeepSeek has made significant advancements without access to advanced U.S. technology, highlighting its capabilities.
- Changing Business Models: As an open-source provider, DeepSeek challenges traditional revenue models of U.S. firms that charge for subscription-based services.
- Geopolitical Dynamics: Operating out of China, DeepSeek raises alarms about U.S. dominance in the AI sector.
DeepSeek’s Privacy and Security Issues
The growing attention towards DeepSeek has not come without challenges. The company has faced bans from multiple governments and organizations due to ethical, privacy, and security concerns, especially regarding data stored in China. Bans are in place from agencies in Australia, India, Italy, and various branches of the U.S. government.
Additionally, DeepSeek reported experiencing a sizable cyberattack on January 27, 2025, coinciding with the rising popularity of its AI assistant. This attack led the company to limit new user registrations temporarily, although services continued for existing users.
Recent Security Breaches
In a troubling turn of events, Wiz Research uncovered a back-end database containing sensitive information related to DeepSeek that was inadvertently exposed to the web. This included chat logs and API keys, posing concerns about user privacy and operational security. DeepSeek promptly took steps to secure the database after being alerted to the leak.
As the landscape of AI continues to evolve, the developments at DeepSeek represent a pivotal moment, showcasing not only the rapid advancement of technology but also the growing complexities related to ethics, security, and global competition in the field of artificial intelligence.
