OpenAI’s ChatGPT

OpenAI’s GPT-3 became the talk of the town as soon as it was launched. People were just not impressed but also quite surprised to see how amazingly GPT-3 could mimic the natural conversation tone. This happened mainly because the previous versions, GPT-1 and GPT-2, provided quite underwhelming results. They were repetitive and did not provide much clarity. GPT-3, on the other hand, was quite engaging and provided more human-like answers. It actually felt like conversing with another person on your device.

OpenAI took things further when it launched GPT-4. This version is more creative and efficient when it comes to generating better results. However, that is not the only benefit. You can now integrate various apps into ChatGPT.

Professionals using Microsoft Word, Excel, Teams, etc., can integrate the APIs into ChatGPT to improve efficiency. Currently, it holds a massive 59.5% market share in the AI chatbot segment.

DeepSeek: The Open-Source Challenger

When ChatGPT was dominating, DeepSeek quietly emerged as a strong alternative in January 2025. Although DeepSeek released its first model, “DeepSeek Coder,” on November 2nd, 2023, the latest model, “DeepSeek-R1,” released in January 2025, gained a lot of attention because of its advanced AI capabilities.

However, DeepSeek did not receive this global popularity only because of its advanced AI capabilities. The main reason businesses are running after Deepseek is because it is an open-source model. This means it will be more cost-effective and can be customized easily. So, developers, researchers, and enterprises that need more control over their AI tools prefer it.

Also, DeepSeek is a better option for organizations that want data privacy and security. Since ChatGPT operates primarily in the cloud, there is a certain degree of risk involved. With DeepSeek, there is no such issue. This AI model offers you the flexibility of local deployment. Local deployment means organizations can run AI models on their own infrastructure.

Since DeepSeek is an open-source model, developers can fine-tune it to fit specific cultural and linguistic needs. As a result, DeepSeek is gaining popularity in areas like Asia and Eastern Europe that require more localized AI solutions. Get support for CodeCurators for custom AI agent and app solutions.

Even though DeepSeek does not have the same brand recognition as ChatGPT, it is still proving itself to be a strong challenger. DeepSeek’s open-source model and lower costs are attracting enterprises that want flexibility without the premium price tag.

DeepSeek and ChatGPT: Basic Overview

DeepSeek vs ChatGPT: Features Compared

We have compared the abilities of both AI models so that you can clearly understand the differences.

Performing Mathematics

1. ChatGPT

If you need assistance with mathematics, avoid ChatGPT. While you can use it for maybe subtractions or divisions, it cannot do complicated math problems. There are very high chances of errors. So, the bottom line is that you can never rely on it.

2. DeepSeek

Since logic-based tasks are its strong suit, you can use it for data analysis and research-heavy applications. DeepSeek, in most cases, provides accurate results. So, DeepSeek is certainly a better option in this case.

Coding

1. ChatGPT

You can use ChatGPT for coding, but it is not recommended. Always remember that its abilities are limited, and it can only perform basic coding tasks. For complex coding tasks, you need an experienced professional.

2. DeepSeek

By now, it must be clear to you that DeepSeek is designed for technical tasks. Performing complicated coding tasks is not a difficult task for DeepSeek. Also, you can code in almost any language you want — this model supports multiple programming languages.

Maintaining Security

1. ChatGPT

If you are worried about privacy, avoid using ChatGPT. Since this is a cloud-based model, your data’s security is dependent on OpenAI’s infrastructure. If OpenAI’s infrastructure gets compromised, you may have to deal with a serious case of data breach.

However, the chances of a data breach are very low because of OpenAI’s strong infrastructure.

2. DeepSeek

With DeepSeek, you have the option of deploying it locally. Therefore, companies using DeepSeek will have complete control over their data and do not have to rely on any third party. Government institutions or sectors like banking and finance may find the feature very appealing.

Conversational Flow

1. ChatGPT

Using ChatGPT often feels like talking to your personal assistant. Whatever question you may have, ChatGPT has an answer for you. And the way it explains, it feels like you are talking to a real human. You can ask for follow-up questions, ideas, or instructions in a very conversational tone. This feature makes ChatGPT a great option for customer support, chatbots, etc. Also, you can even talk to it like a friend and have deep conversations.

2. DeepSeek

Chatting with DeepSeek does not exactly feel like a conversation. Rather, it feels very flat and restricted. The structured responses do not resemble a human. It can be used by developers, researchers, or anyone who prefers straightforward responses for technical writing, reports, research papers, etc.

Type of Content

1. ChatGPT

You can use ChatGPT to create a wide variety of content. These include blogs, social media copies, website content, product descriptions, and whatnot. It will very carefully follow your instructions and provide content that is coherent to your needs. Similarly, you can ask for media campaigns. It can help you strategize and brainstorm.

2. DeepSeek

You cannot expect DeepSeek to give creative responses. It was never designed for that purpose. DeepSeek will provide you with logical answers based on facts. Therefore, using it makes more sense when you need AI for technical writing.

Customization

1. ChatGPT

ChatGPT allows you to integrate various APIs. However, you cannot exactly customize it. The only option users have is to tweak parameters, like Temperature and Max Tokens, to some extent, but that has no impact on the core model.

2. DeepSeek

Since DeepSeek has an open-source model, users can easily modify it. You do not get this freedom with ChatGPT. This is why many businesses prefer it for customized AI solutions.

Which One Should You Choose?

We do not suggest choosing any AI model randomly. You will first have to understand your needs and then decide.

• Tech-Professionals: If you are handling specialized tasks in programming or data science, DeepSeek will likely serve you better. It is better for complex jobs. You get flexibility and precision when working on deep technical challenges or analyzing large datasets. ChatGPT can assist with simpler coding queries but does not match DeepSeek’s capability for technical work.

• Content Creators and Marketers: For those focused on generating creative content, ChatGPT is a strong tool. You can draft a blog, compose a catchy social post, generate ideas, create images, etc., for a marketing campaign. Its strength lies in content creation and ideation, making it particularly useful for writers or marketers. On the other hand, DeepSeek isn’t designed for this type of creative workflow, and it would be less effective in such roles.

• Enterprises with High Privacy Standards: In fields where data security is a top priority, like healthcare or government, DeepSeek has an edge. This AI allows you to keep models running locally. So, you will have full control over any sensitive data. This approach is ideal for organizations that cannot afford any risks with privacy.

ChatGPT or DeepSeek: Who Will Win the AI Race?

You must first understand that both models are currently in the development stage. So, there is still a lot more we can expect from them in the coming years. Reaching a conclusion now would be rushing it. For now, we should just wait and watch.
