What is DeepSeek?
DeepSeek is an artificial intelligence company founded in Zhejiang, China in 2023, focusing on developing advanced large-scale language models. Its product DeepSeek AI has been further improved from the initial version DeepSeek V2, DeepSeek Coder V2, DeepSeek V2 Chat, to the current DeepSeek-R1 and DeepSeek V3. NVIDIA claims that DeepSeek-R1 is the most advanced large-scale language model. As DeepSeek R1 is an open-source LLM, you can run it locally with Ollama.
Why does it attract lots of attention? One great reason is that DeepSeek is free for all users without any restrictions. Of course, developers or businesses need to pay to access the DeepSeek API. However, its fee is relatively low, US$0.27 per million token inputs and US$1.1 per million token outputs, and has been favored by many clients. On Feb 5, 2025, DeepSeek has temporarily suspended API services recharges due to current server resource constraints.
How to Use DeepSeek AI outside China?
The steps for using DeepSeek AI are very simple. You just need to log in to start chatting with its AI chatbot.
Step 1. Go to DeepSeek official site and click Start Now button.
Step 2. Sign up with your email to create a DeepSeek account. One DeepSeek account enables you to access all DeepSeek services.

Step 3. After inputting the code sent to your email, you can start chat with DeepSeek.
What Can You Do with DeepSeek AI?
DeepSeek AI has powerful capabilities in both information collection and integration and data analysis. But it is worth noting that DeepSeek currently only focuses on processing text-related content and cannot generate pictures or videos. Let’s take a look at what we can do with DeepSeek AI.
Ask questions for an instant answer
DeepSeek AI can understand your questions and give corresponding answers. Its powerful knowledge base covers various subjects such as science, history, common sense. Not only that, it will automatically bold the most important information points, allowing users to get key information at a glance, as shown below.

Generate content for various purposes
DeepSeek can also be used as an AI content generator to generate stories, reports, articles, scripts, etc. It supports the creation of multiple scenarios and provides inspiration and ideas for your creation.
Here I tried to use DeepSeek to generate a short story with the recently popular Ne Zha as the protagonist.

Data analysis and key info extraction
DeepSeek can process a variety of data and extract the key information. DeepSeek supports uploading various pictures and files (Excel, CSV file, Word, etc.), and expressing what you want through text, such as describing the picture, obtaining key information in the document, extracting part of the information in the table, etc., to quickly obtain the core content.
Code assistant
DeepSeek-Coder-V2 is an open-source Mixture-of-Experts (MoE) code language model, which can achieve the performance of GPT4-Turbo. The current version, DeepSeek-Coder-V2, has expanded the programming languages to 338 and the context length to 128K. You can even ask it to write codes for games or other programs.
Math solver
DeepSeek, with strong logical thinking and reasoning abilities, can help solve math and other learning problems. It can be regarded as an AI homework helper as well. I tested it with a simple math equation, and it gives answers along with detailed problem-solving processes.
In addition, many Chinese companies have already connected to DeepSeek's API to further optimize logical reasoning, content generation, etc. We also expect the flexible application of DeepSeek in various fields.
Some comments on DeepSeek
We can see many authoritative media reports on DeepSeek online, and the majority gives a positive feedback. Here we intercepted some words from BBC News and The New York Times about DeepSeek.
“The speed at which the new Chinese AI app DeepSeek has shaken the technology industry, the markets and the bullish sense of American superiority in the field of artificial intelligence (AI) has been nothing short of stunning.” From BBC News
“It was able to solve some complex math, physics and reasoning problems I fed it twice as fast as OpenAI’s ChatGPT. When I asked it questions about computer programming, the types a job applicant might be faced with in a technical interview, its responses were as in-depth and speedy as its competitors.” From The New York Times
Which Countries Have Banned DeepSeek?
Since DeepSeek became popular abroad, governments around the world have expressed concerns about DeepSeek. Many governments have explicitly announced that government employees are prohibited from downloading and using DeepSeek, including the US, Australia, Italy, South Korea, and Taiwan. It is not difficult to guess that more countries or agencies may ban DeepSeek in the future.
Some government officials said that because DeepSeek has publicly stated the relevant privacy policy, it means that the personal information it collects will be stored on a secure server in China. For this reason, many people are worried that China will steal the data of foreigners and use it for other purposes.
Is DeepSeek Safe?
As we said before, many countries and governments have expressed concerns about it. According to its privacy policy, user data including chat and query history data will be collected. Of course, the biggest concern is that DeepSeek's servers are in China, and they believe that China would steal the data of users outside China. Among them, a Research Scholar in Law and Senior Fellow at Yale Law School's Paul Tsai China Center, Samm Sacks mentioned: "That data, in aggregate, can be used to glean insights into a population, or user behaviors that could be used to create more effective phishing attacks, or other nefarious manipulation campaigns."
In fact, there is no clear evidence that the Chinese government has taken such actions, but they are still concerned about the potential data risks brought by DeepSeek.
ChatGPT VS DeepSeek: Top Industry-Leading AI Chatbots
First, let’s start with the price difference that everyone is concerned about between the two tools.
Price of ChatGPT:
Free version: Limited access to GPT-4o
Plus: $20/mo [access to multiple reasoning models (o3-mini, o3-mini-high, and o1)]
Pro: $200/mo [Unlimited access to all reasoning models and GPT-4o]
Price of and DeepSeek:
Free (no limitations)
Note: It only charges from developers and businesses for its API service with significantly cheap price.
To test their performance, we ask the same questions and find the differences. (Currently, the tests of both tools are conducted on their free versions.)
Example 1: Statement of objective facts
Questions: When TikTok restore its service in the US?
Answer from ChatGPT:

Answer from DeepSeek:

From the answers of the two AI chatbots, we can see that their results are similar, and both give the answer to the question in the first sentence. The difference is that DeepSeek bolds the key information date, so that users can immediately focus on the key points. Both tools also supplement some relevant additional information, such as why it is banned and why its ban is lifted, and also gave some links to relevant articles.
ChatGPT gave three reference links, while DeepSeek gave 8 reference links. Relatively speaking, the references given by DeepSeek are more comprehensive. Moreover, DeepSeek gave an additional information that users are interested in, that is, although TikTok has resumed its services in the United States, it is still not available for downloading in the Google and Apple app stores.
So personally, DeepSeek's results are slightly better than ChatGPT's on the whole.
Example 2: Image generator
Image description: A cat sleeping soundly in a peaceful and serene environment.
Result from ChatGPT:

Result from DeepSeek:

If you want to use AI chatbot to generate images, then ChatGPT chatbot is better. It can quickly generate images based on the prompts you enter. DeepSeek chatbot cannot generate images directly, but you can use its JanusPro model to generate images in another page.
Example 3: Video generator
Video description: A dog running in a sunshine day on the grass ground.
Result from ChatGPT:

Result from DeepSeek:

Can DeepSeek generate videos? From the results, we can see that both tools cannot generate videos. The result given by ChatGPT is very simple. It first explains that the video cannot be generated, and then tells users to generate image sequences first or use other video creation tools. There is no other information. Even though, ChatGPT has dedicated AI video generator.
DeepSeek is different. It not only provides video generation tools, but also gives video scripts, accurate to every second . As a user, the result of DeepSeek is more meaningful for reference.
Considering the price and features of both, and leaving aside other in-depth factors such as security and country, I prefer DeepSeek.
