A Comprehensive Analysis of the AI Titans in 2025: DeepSeek vs. ChatGPT

“The AI Titans in 2025: DeepSeek vs. ChatGPT”

US President Donald Trump has called the rise of the Chinese AI program DeepSeek “a wake-up call” for the US IT sector after it shook financial markets.

DeepSeek’s assertion that its R1 artificial intelligence (AI) model was developed at a fraction of the price of its competitors has sparked concerns about the industry’s future and led to a decline in the value of some of the largest businesses in the world.

Within a week of its release, DeepSeek has risen to the top of the US app download charts.

How does it stack up against its more well-known and reportedly more costly US competitors, including Google’s Gemini and OpenAI’s ChatGPT?

I was immediately captivated by ChatGPT version 3.5 when I used it for the first time not long ago. It was not only how quickly it solved issues, but also how well it simulated human speech. With ChatGPT igniting a furious competition among AI chatbots, that moment signaled the start of an AI revolution.

DeepSeek R1, a state-of-the-art large language model (LLM) that is creating waves with its remarkable capabilities and affordable cost, is one of the new competitors that are upending the market. This up-and-coming force is presenting itself as a strong rival to ChatGPT from OpenAI. We’ll examine DeepSeek R1’s features, functionality, and overall worth in this post. We will test both of the AI chatbot’s everyday jobs in addition to this comparison. Thus, you can choose the model that best suits your requirements.

We’ll help you determine which model performs better in routine chores and business use cases by looking at their real-world implementations.

Task of Content Creation

I’m not a huge believer of AI-based writing as a writer, but I do believe it can be helpful for ideation, creating talking points, and identifying any holes. In order to test this, I requested that DeepSeek and ChatGPT draft an article outline explaining what LLM is and how it operates. I inquired, “Please give me the points I should include in my in-depth article on what LLM is and how it works so that users can better comprehend the LLM models.” Assist me in creating an outline.

DeepSeek Reaction:

The outcomes were striking. Both AI chatbot models addressed every important issue I could include in the piece, but DeepSeek went above and above by structuring the data to align with my preferred method of approaching the subject. It also contained significant points. Definition, Evolution, Milestones, Examples (GPT, BERT, etc.), and LLM vs. Traditional NLP are all topics that ChatGPT totally overlooked.

To be honest, when I first saw this, I was astounded. DeepSeek even displayed the reasoning behind its conclusions. Even if full artificial general intelligence is still a long way off, the fact that a machine can think like this demonstrates how far we’ve come. I’ve included a brief transcript of the thought process below because it was so fascinating.

Citations “All right, so I have to assist the user in creating an article outline that explains what LLMs are and how they operate. I’ll begin by reviewing my knowledge of LLMs. I take it they’re big language models? such as BERT, GPT-3, etc. The customer most likely wants a thorough outline that divides the subject into manageable chunks. Let me consider the main topics that need to be discussed.

ChatGPT Academic Content Writing Test Analysis of the Question

We were given a simple Physics (Laws of Motion) question in our subsequent DeepSeek vs. ChatGPT test to see which one provided the greatest and most detailed response. “Calculate the momentum of a ball thrown at a speed of 10 m/s and weighing 800 g” is the question we posed using DeepSeek and ChatGPT.

DeepSeek Response:

All right, let’s check. I have to figure out the momentum of an 800-gram ball thrown at 10 meters per second. Momentum, hmm. I recall that mass and velocity are related to momentum. If my memory serves me correctly, the formula is momentum = mass * velocity. Consequently, p = m * v. Yes, it appears to be correct. But hold on, this mass is stated in grams, correct? I should definitely convert grams to kilograms first because that is the conventional unit of mass in physics. I’ll verify that.

DeepSeek remembers and evaluates the information we have provided. However, DeepSeek overlooked a lot of things during the computation process. For example, DeepSeek only wrote the formula for momentum.

p

=

m

×

v

p=m×v

What “p” and “m” stand for, and so forth, are not explained. There is no problem with the computation procedure if we can see the answers.

Coding Task

Checking coding proficiency is the next step in the DeepSeek vs. ChatGPT comparison procedure. We were required to use HTML, JS, and CSS to build code for a basic calculator as part of the test. Given our knowledge that neither of the AI chatbots can perform full-fledged coating, we have assigned them a little assignment to test their coding prowess.

DeepSeek Response:

As we previously stated, DeepSeek began developing the code after recalling every point. Now, if it says true, I have to correct DeepSeek twice before it gives me the correct code for the calculator. The calculator’s interface is more user-friendly and entertaining.

ChatGPT Response:

As is well known, ChatGPT did not perform any deep thinking or recall tasks; nonetheless, it did not make any mistakes and gave me the code at the first request. On the other hand, the calculator’s interface is not very user-friendly or interesting. A dropdown menu for selecting the arithmetic operators was made by ChatGPT. Additionally, unlike DeepSeek, there is no obvious mechanism to clear the result.
