New AI inventions are shaking the world. Specially, we saw a big AI revolution in early 2025. ChatGPT, DeepSeek, and Qwen 2.5 are now at the peak of hype! These AI models are designed to assist users in various tasks, such as content creation, coding, data science, customer care, and more.
But which one is the best? Actually, it totally depends on your needs. Every model has their own strong and weak sides. But they can help you in various fields of technology. Now we will firstly know about the three models and their company. Then we will try to view their efficiencies from various angles. So, check it out!
Structural Types of These Three AI Models
ChatGPT, developed by OpenAI, is a powerful language model that understands and generates human-like text. It’s great for tasks like answering questions, writing essays, summarizing documents, and more. DeepSeek, created by the company DeepSeek, specializes in technical tasks, especially coding and mathematical terms.
It helps developers write code efficiently and debug errors, making it a favorite among programmers. Qwen 2.5, built by Alibaba Cloud, is a multimodal AI designed for diverse uses, such as analyzing long documents, supporting multiple languages, and extracting data from forms.
Purpose-Wise Performance of the AI Chatbots
Firstly, you have to identify why will you use them. Because each of them is not equally skilled in every sector. We tested the free versions of all of these AI tools. We are sharing our experiences in different fields of technology.
WH Questions
“WH questions” mean all those things that we want to know about using question words like What, When, Which, How, etc. The answers to these queries are usually not lengthy. For example, if you ask ChatGPT “What is Voice Dysphoria?”, its answer won’t be long. There, we use AI chatbots for very general purposes. So, their answers to the same questions will be the same. Here you can find their result very close to equal.
Content Writing
I found Qwen 2.5 Max excellent for creating organized and engaging content. Its writing tone, form & style just surprised me! Though sometimes it takes a few seconds more to generate a new blog, I liked it most. If you’re a content writer & looking for the best AI tool, Qwen 2.5 Max might be your top choice. It is super smart and can help you write stories, blogs, or even school essays easily.
Next, ChatGPT is in second position. It helps much from creating content ideas to brainstorming. But it sometimes uses words that would make someone realize that it is an AI content. This is why Qwen 2.5 is ahead of ChatGPT. Another tool, DeepSeek, is also good, but not as smart as the two others.
Coding Assistant
If you’re a coder or programmer, DeepSeek might be the best AI tool for you. It is specially designed to help with coding and understanding programming languages like Python, Java, C++, and more. DeepSeek can solve tricky coding problems and even explain how the code works in simple words.
While ChatGPT is also helpful for coding, it focuses on many tasks, so it’s not as specialized as DeepSeek. On the other hand, Qwen 2.5 Max is great for creating ideas and organizing projects but isn’t as strong in deep coding tasks.
Mathematical Tasks
When it comes to math problems, DeepSeek is the best. This is designed for complex math, perfect for students, teachers and professionals. It can do algebra, geometry and even advanced problems step by step. It explains solutions clearly. This AI tool is great for building math skills whether you’re in school or getting prepared for exam. From simple equations to tough calculations, it is the top AI for math.
Customer Care Support
When it comes to picking the best AI tool for customer care, ChatGPT is the top choice. It is like a super-smart assistant that can chat with customers, answer their questions, and solve problems in a friendly way. It understands what people are asking and gives clear, helpful answers, making customers feel valued. This makes it perfect for businesses that want to provide fast, reliable, and friendly customer support.
Documented Tasks
DeepSeek is good at creating, organizing and summarizing documents with high accuracy. It helps users write reports, research papers and step-by-step guides fast. Businesses and students can use it to store and manage information without errors. It also helps in summarizing long documents into short and simple points. It understands complex topics and turns them into well written and easy to read content. This AI tool ensures all documented tasks are clear, professional and well organized. The accuracy of its answer is very well also.
Image Generation
First of all it, it should be kept in mind that these models are not perfect for AI image or video generation yet. Despite this, we have tried creating images with their free versions. DeepSeek can’t generate image. But the two other chatbots can create image by prompt. I just gave same prompt to both ChatGPT & Qwen 2.5-“A cat is eating a banana”. Then they delivered me about same results. The resolution, the visualization, and the quality of the images were very close.
Thoughts about privacy policy
Every AI tool has their own privacy policy. OpenAI the company behind ChatGPT follows Western data protection standards. It is trusted by many companies worldwide as it follows global privacy laws. You can use these tools for many reasons. But when it is matter of high privacy, you can choose ChatGPT.
Which AI Model is Right for You?
Choosing the best AI model depends on your needs. If you’re a content writer, Qwen 2.5 Max shines with its creative and engaging writing style. For coders or programmers, DeepSeek is the go-to tool because of its expertise in coding and math problems. And if you’re looking for customer care support or general question-answering, ChatGPT performs exceptionally well. Each model has unique strengths—Qwen excels in creativity, DeepSeek in technical tasks, and ChatGPT in versatility.
For privacy-conscious users, ChatGPT’s strong data protection policies make it reliable. Meanwhile, if you need help with documents or math, DeepSeek is unmatched. Though none of these models are perfect for professional AI image generation, Qwen and ChatGPT can still create visuals.
In short, there’s no “one-size-fits-all” AI. Think about what you need most—whether it’s writing, coding, math, or customer support—and pick accordingly. By understanding their strengths, you can find the perfect AI assistant to boost your productivity and creativity!
