DeepSeek Explained: What It Is and How It Works

What is DeepSeek?

DeepSeek is an advanced AI chatbot that has gained significant popularity since its launch in early 2025. Developed by Liang Wenfeng, it is an open-source, free-to-use reasoning model designed to compete with leading AI tools like ChatGPT. With its sophisticated AI models, DeepSeek supports a wide range of applications, including mathematics, coding, and text generation.

Unlike many commercial AI tools, DeepSeek is cost-effective, requiring only an estimated $6M for training—significantly less than OpenAI’s GPT-4o. This affordability, coupled with its high efficiency, has positioned DeepSeek as a strong alternative to mainstream AI models.

What Makes DeepSeek Unique?

DeepSeek’s rapid growth, reaching over 20 million users within 20 days of its launch, highlights its distinctive features:

1. Multiple AI Models for Different Functions

DeepSeek is not a single AI model but a collection of specialized models, including:

• DeepSeek-R1 – Reasoning AI model
• DeepSeek-V3 – General-purpose AI model
• DeepSeek-Coder – Coding-specific AI model
• DeepSeek LLM – Text generation AI model

2. Open-Source Accessibility

Unlike many competitors, DeepSeek offers open-source AI models. This allows developers and businesses to inspect, modify, and even integrate these models into their own applications without licensing fees.

3. Cost and Efficiency

DeepSeek operates with reduced hardware requirements, utilizing less memory and power while maintaining high performance. This makes it more accessible to users worldwide.

4. Self-Correcting Capabilities

DeepSeek uses a step-by-step reasoning method, allowing it to analyze mistakes and correct them in real-time. This ensures more accurate and reliable responses, particularly in complex tasks like coding and mathematics.

How Does DeepSeek Work?

DeepSeek employs a Mixture-of-Experts (MoE) approach, meaning it dynamically selects specialized models based on the type of request. This results in:

• Faster response times
• Reduced computational overhead
• Higher accuracy in domain-specific queries

This approach ensures that users get the best possible responses without unnecessary processing power consumption.
