In the future society, there will only be two types of people: those who master AI and those who cannot utilize AI. DeepSeek is currently the world’s strongest AI, and it is from China, understanding Chinese the best, and importantly, it is free. Why not start using it quickly?
1. Understanding DeepSeek.
Recently, DeepSeek has taken the world by storm! It has given our countrymen a sense of pride! The name DeepSeek represents the rise and breakthrough of Chinese AI technology.
DeepSeek is a very powerful AI chat tool that can help you quickly solve problems and improve work efficiency.
DeepSeek achieves performance comparable to, or even surpassing, top international AI models at an ultra-low cost. The training cost is only $5.576 million, yet it reaches the level of Gpt-4o, which has a training cost exceeding $100 million. This has shown the world the pioneering and leading innovative strength of Chinese tech companies!
DeepSeek’s success is a perfect comeback for Chinese tech companies on the international stage, showcasing China’s strong capabilities in the AI field and igniting our national pride.
DeepSeek, officially known as “Hangzhou DeepSeek Artificial Intelligence Basic Technology Research Co., Ltd.”, abbreviated as “DeepSeek”, was founded on July 17, 2023, by Huanfang Quantitative in Hangzhou’s Gongshu District. It is an innovative tech company focused on developing advanced large language models (LLM) and related technologies.
On January 5, 2024, the company released its first large model, DeepSeek LLM, followed by models such as DeepSeek-Coder, DeepSeek-VL, DeepSeek V2, and DeepSeek V3. Among them, the DeepSeek V2 model attracted industry attention for its outstanding performance in comprehensive Chinese capability assessments and low inference costs, earning the nickname “the Pinduoduo of AI”.
On January 20, 2025, the company officially released the DeepSeek-R1 model and simultaneously open-sourced the model weights. The performance of DeepSeek-R1 is close to that of OpenAI’s o1 official version, but the inference cost is only a fraction of OpenAI’s o1.
On January 27, 2025, the DeepSeek app topped the free app download charts in the Apple App Store in the United States, surpassing ChatGPT in the US download rankings. On the same day, the Apple App Store free list in China showed that DeepSeek became number one.
On January 28, 2025, DeepSeek released the open-source multimodal model Janus-Pro, where the 7 billion parameter version of the Janus-Pro-7B model excelled in the image generation rankings using text prompts, outperforming OpenAI’s DALL-E 3 and Stability AI’s Stable Diffusion.
As of February 2, 2025, DeepSeek topped the download charts in 140 countries’ Apple App Store and also ranked first in the Android Play Store in the US.
On February 6, at 19:46, DeepSeek announced on its official WeChat account that it had recently noticed some counterfeit accounts and misinformation related to DeepSeek that misled and troubled the public. To protect user rights and reduce the adverse effects of false information, the following explanations regarding official accounts are provided:
Currently, DeepSeek has only one official account on the following social media platforms:
WeChat Official Account: DeepSeek,
Little Red Book: @DeepSeek (deepseek_ai), X (Twitter): DeepSeek (@deepseek_ai).
DeepSeek stated in its official announcement, “The DeepSeek official web version and the official genuine app do not contain any advertisements or paid items. Currently, apart from the official DeepSeek user communication WeChat group, we have never set up any groups on other domestic platforms. Any claims of charging related to DeepSeek official groups are fraudulent. Please carefully discern to avoid property loss.”
The core construction method of DeepSeek is divided into four parts: data end, model end, optimization end, and alignment. The first three parts are in the pre-training stage of the model, while the alignment stage uses SFT for human-style alignment.
DeepSeek has both a web version and an app version, and both are currently free to use.

8. DeepSeek Questioning Skills:
(1) Use Simple Language for More Efficiency:
No need for complicated formats, just ask questions as if chatting:
2. Skill summary: Treat the question as a task for a younger generation, clearly stating the three elements of “who uses it, what to do, and desired results”.
(2) Universal Question Formula:
When faced with complex problems, remember this practical template:
“I want to 【do something】, for 【someone/somewhere】, seeking 【desired effect】, but concerned about 【some problem】”.
Example in grocery shopping: “I want to steam bass for my partner with high blood pressure, seeking deliciousness but worried about the fishy taste not being cleaned properly”.
→ Will receive: detailed steps + healthy seasoning alternatives + fishy smell removal tips.
(3) Rephrase for Clarity:
When the answer is too technical, add this magical command: “Please explain in a way that even a market vendor can understand”. Comparison example:
1. Original answer: “Optimize video transmission rate by enhancing household network bandwidth”
2. After adding command: “It’s like replacing your home network cable with a thicker pipe so that videos from your grandson won’t freeze into mosaics”.
(4) Three-Step Self-Check Method:
Ask important questions this way for more peace of mind: “First give suggestions, then identify three possible issues, finally provide solutions together”.
Medical consultation example: Input: “Should I use hot or cold compress for knee pain? Please answer using the above method” → Will receive:
-
Suggested plan (explained by situation),
-
Reminders (e.g., cold compress not suitable for arthritis),
-
Solution tips (e.g., towel usage tips).
(5) Make Answers More Personal:
Add these everyday requirements after the question:
1. “Please outline in points” → Answers become clearer,
2. “Give an example from grocery shopping” → Complex concepts become simpler,
3. “Write as if giving advice to an old friend” → Tone becomes friendlier.
For example, ask: “What should I pay attention to when managing pension funds? Summarize in three points and give a savings example at the end”.
(6) Situational Approach:
When facing difficult issues, ask questions this way for better results: “If you were 【an experienced person】, how would you handle…” Practical scenarios:
1. Home appliance repair: “Assuming you are a 20-year veteran appliance repairman, what should I do if my refrigerator’s cooling compartment is frozen?”
2. Taking care of a grandson: “If you were a top kindergarten teacher, how would you encourage a 5-year-old to do their homework?”
(7) Important Information in Quotes:
When looking for specific content, remember to put key information in “” or ” like:
1. Check policy: “Shandong Province ‘Only Child Subsidy’ New Regulations for 2024”
2. Find lyrics: “Looking for the lyrics of 《My Country and I》”
