Both ChatGPT and DeepSeek have made a place for themselves in the world of advanced technology and deep learning. Over the years, DeepSeek has been established as a well-known competitor to ChatGPT. As an open-source chatbot, it is a great cost-effective choice, when it comes to technical and mathematical sectors.

However, ChatGPT is not that bad either. It is still a widely used tool due to its user-friendly interface and multitude of features. Moreover, we can’t deny the existence of DeepSeek either. So which one should you choose? That’s where it gets overwhelming. On the surface, both ChatGPT and DeepSeek look similar.

That’s where you need to know the differences. Thus, in today’s blog, we will try to compare the two to help you identify your ideal chatbot assistant. By the end of today’s post, you will have a better idea of the overview, usage, features, and areas of expertise of both.

An Overview of DeepSeek

Did you know that the cost to develop DeepSeek was just around $6 million? This amount is just a fraction of the money invested to create other models.

Simply put, DeepSeek is a chatbot, which provides you with assistance during various tasks. What makes it stand out from generalized models is how specific it is in offering personalized and highly accurate responses. Overall, it’s a preferred tool for anyone who needs, accurate and detailed responses. For example:

• Marketers wanting in-depth research assistance
• Coders that need optimized solutions

DeepSeek claims to provide you with satisfactory responses, to fulfill user requirements. Here are some key points to remember about the tool.

• It can seamlessly integrate with other tools, apps, and workflows because of open-source APIs.
• It is free to use, making it accessible worldwide.
• DeepSeek is affordable and scalable due to the use of a self-learning model that doesn’t need human supervision.

It’s because of DeepSeek’s affordability and accessibility that it rose to popularity and became the most downloaded app on the App Store as of January 27, 2025.

An Overview of ChatGPT

Did you know that since it was launched in November 2022, it has become highly popular among users due to its user-friendly interface and accessibility?

ChatGPT is the original generative chatbot assistance that came way before DeepSeek. Due to its conversational capabilities and varying applications in multiple sectors, it is one of the most widely used artificially intelligent tools.

ChatGPT can do everything from email drafting and brainstorming ideas to coding and writing essays, and everything that comes in between. Its capabilities to handle multiple tasks of varying complexities makes it well-known among: 

• Writers
• Students
• Professionals
• Hobbyists  

Here’s what everyone needs to know about this tool.

• Anyone having a connection to the internet can use it.
• Its free version is a preferred choice among users across various parts of the world.
• It can chat like a person.

OpenAI released the new versions of the tool known as ChatGPT01 and ChatGPT01 as early as the end of the last year.

DeepSeek vs ChatGPT: The 5 Differences

Now, we are clear as to why both DeepSeek and ChatGPT are exceptional tools. However, even after knowing all these useful insights, we are still not clear as to what sets them apart. So for starters, let’s take a look at 5 differences between the 2 artificially intelligent digital assistants.

1. Structure

Both ChatGPT and DeepSeek have different technicalities. The latter uses an MoE or mixture of experts, approach. 

Both ChatGPT and DeepSeek differ when it comes to technicalities. The newer tool among the two implements a mixture of expert (MoE) techniques.

• We can say that MoE is close to keeping an expert team nearby, where only the most relevant members are required and called upon for a particular task. 
• DeepSeek shows enhanced efficiency as it only activates a few points for each request although it is equipped with 650 billion knowledge points.
• This method lets it streamline performance and resource usage, which allows it to adapt to varying queries from different users. 

However, when talking about ChatGPT, it implements a traditional approach. That is a consistent yet less efficient transformer. When we explain it in layman’s terms, it is like everyone working on all tasks.

2. Performance 

Both the tools we are talking about are dominant in specific areas and sectors of expertise. When we talk about DeepSeek, it excels at technical tasks with up to 90% accuracy in even the most complicated subjects including mathematics. However:

• ChatGPT is better at understanding the context
• It offers refined responses throughout a multitude of topics.

3. Cost & Accessibility

The greatest difference between DeepSeek and ChatGPT is in how the price and convenience of both tools compare. The latter takes an open-source approach, meaning that anyone can freely use it and the community can make changes to it.  On the other hand, ChatGPT works on a freemium basis. It means that it offers basic features at no cost. However, to use its advanced capabilities, you need to pay.

4. Customization & Usability

If you are comfortable using technical tools, then customizing DeepSeek as per your needs will be easy for you due to the many configurations it offers. On the other hand, ChatGPT offers a user-friendly experience.

5. Development Philosophy

DeepSeek has been developed with providing efficiency in mind. It was made with innovative training methods and less powerful hardware. On the other hand, many computational resources went into the development of ChatGPT. So it takes a more traditional approach to achieve its capabilities.

DeepSeek vs ChatGPT: 6 Feature-by-Feature Comparisons

Now that we are clear with the basic differences, we can move on to the more technical aspects of both ChatGPT and DeepSeek. A feature-by-feature comparison will give you a clear idea of which tool you need to choose for your particular requirements.

1. Writing Assistance

Both ChatGPT and DeepSeek are great at assisting in content creation and documentation. However, their approach to these tasks is slightly different. The former is a better choice when it comes to generating compelling conversational and rich contextual content. On the other hand, DeepSeek has the upper hand in technical writing as it creates precise and formal documentation.

2. Coding & Technical Prompts

It is one of the most essential features for coders. While ChatGPT is a comprehensive coding assistant, that offers explanations alongside its suggestions, DeepSeek generates codes faster with a standard style.

3. Creativity & Brainstorming

Both ChatGPT and DeepSeek are good at creativity and brainstorming. However, only the approach is slightly different for both. While ChatGPT will provide multiple solutions to a problem DeepSeek provides fewer but thorough approaches. Think of it as multiple-choice answers vs essays.

4. Research & Learning

Here, ChatGPT generates explanations that read more like tutorials. It is great at breaking down complex topics into simple and understandable sections. On the other hand, technically accurate precision and conciseness are what you get when you use DeepSeek.

5. Efficiency & Cost

As we mentioned before, DeepSeek is more cost-effective as it uses edge deployments and energy-efficient hardware, which reduce operational costs. Plus, it’s free and open-source. On the other hand, ChatGPT offers an expensive subscription. However, you get consistent performance and advanced features, which are worth the investment.

6. Ethical & Privacy Concerns

You need to carefully weigh this criterion, especially if you are working with sensitive data. In this aspect, ChatGPT is much safer as it implements Western data protection standards. On the other hand, we had no choice but to raise concerns while looking at DeepSeek’s content moderation and data storage policies.
