Date: January 27, 2025

What is DeepSeek?

DeepSeek is a state-of-the-art artificial intelligence model developed in China, designed as a competitive alternative to global leaders like OpenAI (GPT-4) and Meta (Llama). What sets DeepSeek apart is its focus on efficiency, accessibility, and open source, making it an ideal tool for developers, businesses, and researchers. DeepSeek in English

Origins and Philosophy

DeepSeek was created in 2023 by Liang Wenfeng, a computer engineer and co-founder of the quantitative hedge fund High-Flyer. His experience in quantitative finance inspired a design optimized for tasks requiring high precision, such as data analysis and code generation.

3 Key Principles of DeepSeek:

1. Open Source: Available under MIT license, allowing free download, modification, and redistribution.
2. Cost Efficiency: Resource optimization that drastically reduces training and inference costs.
3. Transparency: Offers the ability to audit and adapt the model to specific needs, something not possible with closed models like GPT-4.

Technical Architecture

DeepSeek uses an innovative architecture known as Mixture of Experts (MoE), which divides the model into "experts" specialized in different tasks. This optimizes resources by activating only the necessary experts for each input.

Key Technical Features:

Number of Parameters: 671 billion total, but only 37 billion active per token.
FP8 Training: Uses 8-bit precision, reducing memory and energy consumption.
Extended Context: Processes up to 128k tokens, ideal for long documents like source code or financial reports.

Why Choose DeepSeek if You Already Use ChatGPT?

If you use ChatGPT, you've likely faced challenges like high API costs, lack of customization, or limited transparency. This is where DeepSeek stands out as a more economical and flexible option.

Intelligent Debugging: Processes error logs and suggests solutions with detailed context.

2. High-Impact Business Automation

Finance: Analyzes meeting transcripts to detect market signals. Generates automated regulatory reports with complete traceability.
Human Resources: Performs intelligent CV screening, identifying ideal candidates for technical roles.

3. Accelerated Research

Academic Papers: Summarizes lengthy arXiv articles and generates actionable hypotheses.
Prompt Engineering: DeepSeek accepts hybrid prompts combining text with UML diagrams or SQL queries.

How to Migrate from ChatGPT to DeepSeek

Try the API in 5 Minutes

import requests
headers = {"Authorization": "Bearer YOUR_KEY"}
data = {
    "model": "deepseek-v3",
    "messages": [{"role": "user", "content": "Optimize this SQL query..."}]
}
response = requests.post("https://api.deepseek.com/v1/chat", json=data, headers=headers)

Cost: $0.55/million tokens, compared to $15 from OpenAI.

Self-hosting for Businesses

Download model weights from Hugging Face.
Use hardware like an RTX 4090 with 24GB VRAM for inference.
Reduce requirements with 4-bit quantization techniques.

Limitations and How to Mitigate Them

Limitations

Content Censorship: Some versions restrict certain topics.
Hardware Requirements: Large models require high-performance GPUs.
Chinese Documentation: Can be a barrier for international users.

Solutions

Run a locally modified version available on GitHub.
Leverage the global community for collaborative translations.
