DeepSeek vs ChatGPT | Comparison of 2 Popular AI Models

Whichever industry you belong to, you must have definitely heard about AI, and the impact of AI on your industry must have come to a certain extent, and you must also be wondering if there is so much AI available in the market, which AI should we use, today we will know about it in details. Today, Artificial Intelligence (AI) is evolving at an incredible pace, and the two major players in the language model space are DeepSeek R1 and ChatGPT. While ChatGPT, developed by OpenAI, has been around since 2022 and is widely used for content creation, coding, and general problem-solving, DeepSeek R1, released in January 2025, is an emerging competitor with a focus on efficiency and technical tasks. Mostly people must be knowing about Chatgpt but Deepseek app has also made its name in a very short time, today we will know about both these AI tools and finally which one among the two is best for you.

Quick Summary

DeepSeek R1 and ChatGPT are powerful AI models with distinct strengths. Released in January 2025, DeepSeek R1 is open-source, cost-effective, and optimized for coding, mathematics, and logical reasoning using a Mixture-of-Experts (MoE) architecture. Its rapid launch and superior features quickly gained popularity.

ChatGPT, developed by OpenAI, is a general-purpose AI excelling in content creation, education, and customer interactions with strong contextual understanding and multimodal capabilities. While DeepSeek is free and ideal for technical users, ChatGPT follows a freemium model ($20/month) and is better suited for professional work and team collaboration. For general use, DeepSeek is a great option, but for advanced features, ChatGPT is preferable.

What is ChatGPT?

At present, maximum people have definitely used ChatGPT, and those who have not used it, they must know about ChatGPT. And this tool is so popular because it is the first advanced tool in the market, from this we can say, basically ChatGPT is a conversational AI developed by OpenAI. It uses a transformer-based architecture and is widely known for its human-like text generation. The model is powerful in creative tasks, research, content creation, and customer interactions. ChatGPT is trained on vast datasets and excels at understanding context, making it an excellent tool for general-purpose use. I and my team personally use ChatGPT for our various works, be it knowing about new ideas or doing research on any topic, this tool has been very helpful for us in the last 3 years.

What is DeepSeek R1?

When DeepSeek was launched, it became quite popular among people within a day, and it became popular mostly in USA and Europe very quickly. When our team tested this tool, we could not believe that this AI tool was new because its efficiency and answering accuracy is quite perfect. DeepSeek R1 is an AI-powered chatbot developed by a Chinese AI company. Unlike ChatGPT, it is open-source and uses the Mixture-of-Experts (MoE) architecture, where only a subset of parameters is activated for each task, making it more efficient. This allows DeepSeek to optimize performance and speed, particularly in logical reasoning, mathematics, and coding. The best feature of Deepseek is that it gives you the Web Search feature, in which you can also do current web search using Deepseek R1 technology.

Core Differences Between DeepSeek and ChatGPT

1. Model Architecture

• DeepSeek R1: follows a Mixture-of-Experts (MoE) approach, selectively activating only the most relevant parameters for each task. This leads to lower computational costs and better efficiency. That is, whatever question you have asked, it tries to answer it in as many correct ways as possible so that the cost can be kept as low as possible.

• ChatGPT: on the other hand, uses a traditional transformer-based model, where all parameters work together, making it more resource-intensive but consistent. That is, the answer you get, its accuracy can be higher compared to Deepseek.

2. Performance Strengths

• Mathematics: DeepSeek R1 achieves 90.2% accuracy on the MATH-500 benchmark, while ChatGPT scores 96.4%. Our team tested a lot of complex maths questions and the result is quite good.

• Coding: Both models perform nearly the same in code generation, with DeepSeek at 96.3% and ChatGPT at 96.6% on Codeforces. But for any coding you do in Deepseek, you need to have coding knowledge as you might need to do manual checks at times.

• General Knowledge: ChatGPT leads with 91.8% accuracy on MMLU (Massive Multitask Language Understanding), while DeepSeek scores 90.8%. According to our tests most of the AI is good in general knowledge, not just Chatgpt, Deepseek but Google Gemini and meta AI are also capable of this.

3. Accessibility and Cost

• DeepSeek R1: is free and open-source, making it highly accessible to developers and startups. But it has been said in many sources that Deepseek's premium plans may also be launched in the next few months.

• ChatGPT: offers a free version but locks premium features behind a $20/month subscription. Token usage is also more expensive. Most of the users of ChatGPT use the free plan.

4. Customization & Ease of Use

• DeepSeek R1: is highly customizable but requires technical knowledge to implement. Without technical knowledge you will not be able to customize it properly.

• ChatGPT: is beginner-friendly, requiring no technical setup. Chatgpt is so popular among the general audience because it has been available in the market for many years, and then people did not have so many options, that is why most people are quite friendly with ChatGPT.

5. Privacy and Data Handling

• ChatGPT: complies with Western data protection standards. Most of ChatGPT's operations are performed from the USA.

• DeepSeek R1: open-source nature may raise privacy concerns in enterprise settings.

Feature Comparison

So if you are also confused, which tool you need to use, then let's know some important feature comparison between Deepseek R1 and ChatGPT.
