Feature-by-Feature Comparison of DeepSeek and ChatGPT

Model Architecture and Technology

DeepSeek Model is based on the Mixture-of-Experts (MoE) framework. It is a model that does not activate all its parameters at the same time. Instead, it chooses only those that are relevant to the specifics of the work at hand. Its DeepSeek-V3 model has 671 billion parameters in total. 

However, only 37 billion are active for each input at any given time. This is what makes it efficient. DeepSeek-Coder-V2 is capable of mastering more than 300 programming languages and takes in data up to 128,000 tokens. If your work involves dealing with lengthy documents or code, that is a huge advantage.

OpenAI’s GPT-4 architecture powers ChatGPT. It is based on a transformer model that fully activates all parameters for each use. The latest version, GPT-4o, is multimodal, which means you can provide it with images, spoken language, or typed text all in a single session. 

There is another version, which is GPT-4.1, that shifts the focus towards improving speed and memory usage. Although this version does not use the MoE approach, it was trained on an extensive dataset, which allows it to maintain reliable performance on various tasks.

Here’s a quick difference:

• DeepSeek saves processing time by using only a limited number of parameters per task.
• ChatGPT maintains a high and consistent quality for each task by using all parameters.
  

Expert Suggestion: If you want flexibility with large files or technical content, DeepSeek might suit you. In the case you want one model to perform all functions seamlessly, ChatGPT is likely the most polished option available.

DeepSeek Coder is developed for intricate coding tasks. It serves over 300 languages and places high in rankings like HumanEval and MBPP. During assessment in actual coding challenges, it often returned accurate solutions in fewer attempts. 

It is solution-oriented and effective at debugging. One example showed DeepSeek solving and explaining a multi-layered Python problem, accomplishing it quicker than other models in the same tests.

ChatGPT explains coding in a more teacher-friendly way. It deconstructs a problem before arriving at a solution, which is helpful for comprehension as to ‘why’ something works. 

It excels at logical deduction and provides helpful, suggestive feedback. If given an error message, ChatGPT doesn’t restrict itself to just correcting the code; it offers explanations for the error’s occurrence, rendering it popular with novices and those seeking to enhance their skills.

For a quick example:

We asked both models to convert a CSV to JSON using Python.

• DeepSeek gave the code in one shot and explained the logic after.
  
• ChatGPT gave the code and explained each line step-by-step before the final output.
  

Expert Suggestion: If you know what you’re doing and just want working code, DeepSeek saves time. If you’re learning or troubleshooting, ChatGPT feels more supportive.

Math Skills

DeepSeek is very good at solving math problems. It can solve algebra, calculus, statistics, and logic-based problems. It has a unique, clear step solution that is specific to its features. 

In benchmarks on math tests, DeepSeek’s accuracy in advanced tasks was as high as 90%. If it is long equations or proofs, DeepSeek provides step-wise answers instead of just the final output.

ChatGPT handles basic to intermediate math problems very well. It is good at doing calculations, dealing with formulas, and solving word problems. GPT-4.1 made some changes in this regard. 

It does have issues with intricate reasoning or higher-level mathematics, as it tends to skip over steps or greatly simplify things. For light homework assistance, ChatGPT is good, but for more intricate tasks, DeepSeek provides more insightful details.

For example, we asked both models to solve an equation involving square roots and variables.

• DeepSeek went over the square root rule, variable isolation, and all algebraic steps.
• ChatGPT arrives at the correct final solution but misses some steps in the middle.

Expert Suggestion: So, if you need full solutions, DeepSeek works better. If you just want a quick answer, ChatGPT does the job.

Problem-Solving and Reasoning

Focusing on logic and step-by-step execution, DeepSeek has an edge in reasoning. It was trained with reinforcement learning to improve reasoning. 

You can ask it to solve puzzles, perform cause-and-effect reasoning, or multi-step tasks. DeepSeek also tends to perform better in coding and logic tests, where he provides structured answers with many details due to his high verbosity.

ChatGPT reasons in a conversational manner. It’s proficient at handling everyday logical queries, but tends to respond in one or two sentences unless prompted to elaborate. 

For other processes such as website creation or content strategy writing, he provides a reasonably detailed step-by-step plan. Its strength lies in real-world reasoning, but less so in abstract logic without sufficient stimulus.

Here’s how they compare with a planning question:

Do a test yourself. Prompt both with the challenge: “How can I set up a blog from scratch?”

• DeepSeek provides an itemized list that includes the tools and platforms needed.
• ChatGPT elaborates on each step by including a few pros and cons and discussing why one option may be better than others.

Expert Suggestion: If you prefer structure, DeepSeek feels clearer. If you want guidance and context, ChatGPT is more helpful.
