DeepSeek vs ChatGPT: Which Is Better for Arabic Users?

Just $5.5 million. That is what it cost to train DeepSeek R1 — compared to over $100 million spent by OpenAI on GPT-4. The figure stunned Silicon Valley and sent American AI stock prices tumbling in a single day.

But does cheaper mean better? And is DeepSeek a realistic option for Arabic-speaking users, or does ChatGPT still hold the lead? These questions need straightforward answers backed by actual testing — not sensational headlines.

What Is DeepSeek and Who Is Behind It?

DeepSeek is an open-source AI model developed by a Chinese company of the same name, founded in 2023. The company is a subsidiary of High-Flyer, a Chinese hedge fund specializing in quantitative trading powered by AI.

What sets DeepSeek apart from its competitors comes down to three key points — and understanding them helps you decide when to use it and when to stick with ChatGPT:

• Fully open source — you can download the model and run it on your own machine
• Extremely low training cost — achieved competitive performance at a fraction of the budget
• Mixture of Experts (MoE) architecture — activates only the parts of the model needed for each task, saving resources

As for ChatGPT, it comes from OpenAI — the company that launched the generative AI revolution in 2022. If you want to learn more about ChatGPT and its competitors, check out our comprehensive comparison of ChatGPT, Gemini, and Claude.

How Does Each Model Handle Arabic?

Arabic performance is the most important question for Arabic-speaking users — and the gap between the two models here is significant. An AI model that excels in English may produce noticeably weaker Arabic output, and this is exactly what our testing revealed.

ChatGPT in Arabic

ChatGPT has supported Arabic since launch and has improved noticeably with every release. The current versions (GPT-4o and GPT-4.5) understand Modern Standard Arabic as well as Gulf, Egyptian, and Maghreb dialects. You can write to it in colloquial Arabic and it will understand you.

Its strengths in Arabic:

• Excellent understanding of context and tone
• Producing long, coherent texts
• Accurate translation between Arabic and English
• Handling Arabic cultural content

DeepSeek in Arabic

DeepSeek was primarily trained on Chinese and English data. Its Arabic support exists but is noticeably weaker than ChatGPT's. In our testing:

• It understands Modern Standard Arabic acceptably but sometimes struggles with dialects
• Its Arabic output is shorter and less fluent
• It occasionally mixes Arabic structures with ones literally translated from English
• It performs better when you ask in English and then translate the result

# Simple test: ask both models to explain a technical concept in Arabic
# then compare the text quality

import anthropic  # or openai / deepseek API

prompt = "Explain the concept of deep learning in Modern Standard Arabic in 3 sentences"

# ChatGPT produces smooth, natural Arabic text
# DeepSeek produces correct but less fluent text

# Result: if Arabic content is your priority — ChatGPT is better

Which Model Is Stronger at Coding and Technical Tasks?

DeepSeek stands out here in a surprising way. On coding benchmarks like HumanEval and MBPP, DeepSeek R1 achieved results very close to GPT-4 — and sometimes outperformed it on specific tasks.

Practical Test: Solving an Algorithm Problem

# Task: find the longest substring without repeating characters
# Longest Substring Without Repeating Characters

# DeepSeek R1's solution — uses sliding window efficiently
def longest_unique_substring(s: str) -> int:
    char_index = {}
    max_length = 0
    start = 0

    for end, char in enumerate(s):
        if char in char_index and char_index[char] >= start:
            start = char_index[char] + 1
        char_index[char] = end
        max_length = max(max_length, end - start + 1)

    return max_length

# ChatGPT's solution — nearly the same approach with clearer explanation
# Both arrive at the correct O(n) solution

The real difference shows up in Chain of Thought reasoning. DeepSeek R1 displays its thinking steps in detail — which is very helpful if you are learning to code and want to understand the solution, not just copy it.

However, ChatGPT excels at:

• Explaining code to beginners in simple language
• Suggesting alternatives and multiple design patterns
• Working with entire projects, not just snippets

How Do the Costs Compare?

DeepSeek is 18-35 times cheaper than ChatGPT for API costs, and offers a free version with no clear limits versus ChatGPT's limited free tier. You can also run DeepSeek locally for free since it is open source — and this difference might be the deciding factor in your choice.

What Are the Privacy Differences?

Both models have different privacy concerns. DeepSeek is a Chinese company obligated to cooperate with its government and stores data on servers in China. ChatGPT retains your conversations to improve the model and shares data with Microsoft. Neither is perfect — the question is which risks matter more to you.

DeepSeek Concerns

• Compliance with Chinese law — Chinese companies are required to cooperate with the government upon request
• Content censorship — DeepSeek refuses to answer politically sensitive questions related to China
• Data storage — The privacy policy indicates data is stored on servers in China

ChatGPT Concerns

Don't assume ChatGPT is problem-free:

• Conversation storage — OpenAI retains your conversations to improve the model (unless you disable this)
• Data sharing — Close partnership with Microsoft
• Closed source — You cannot verify what happens inside the model

The Practical Solution

If privacy is your top priority, DeepSeek's open-source nature offers a unique advantage: you can run it on your own server without sending any data to any third party. This option is not available with ChatGPT.

# Running DeepSeek locally using Ollama
# No data sent to any external server

# Step 1: Install Ollama
# curl -fsSL https://ollama.com/install.sh | sh

# Step 2: Download the model
# ollama pull deepseek-r1:7b

# Step 3: Run it
import requests

response = requests.post('http://localhost:11434/api/generate', json={
    'model': 'deepseek-r1:7b',
    'prompt': 'Explain information security',
    'stream': False
})

print(response.json()['response'])
# Everything runs on your machine — complete privacy

When Should You Choose Each Model?

Rather than declaring a single winner, here are the practical scenarios:

Choose DeepSeek if:

• You are building an application and need a cheap API
• You want to run the model locally on your own server
• You primarily work in English or Chinese
• You need detailed logical reasoning for coding and math
• Your budget is limited and you don't want a monthly subscription

Choose ChatGPT if:

• You write content in Arabic — text, articles, reports
• You need deep understanding of Arabic cultural context and dialects
• You want an integrated ecosystem (web browsing, DALL-E, data analysis)
• You prefer a polished user interface and technical support
• You work on a team and everyone needs a unified tool

Quick Answers

Is DeepSeek better than ChatGPT at math?

DeepSeek R1 achieved very close results to GPT-4o on the MATH and GSM8K benchmarks. The lead alternates depending on the type of problem — but the gap never exceeds 2-3% in favor of either side. If you are a student who needs help with math, both are excellent.

Can I use DeepSeek for free?

Yes. DeepSeek offers a completely free web interface with no clear limits on usage. You can also download the model and run it on your machine if you have a GPU with at least 16GB of memory (for the 7B version).

Is DeepSeek safe to use?

The model itself is safe — especially the open-source version that has been inspected by thousands of developers. The concerns relate to the cloud platform and the privacy policy. If you are worried, run it locally on your machine and avoid the cloud platform.

Which is faster at responding?

ChatGPT is faster for standard responses. DeepSeek R1 is slower because it displays its "chain of thought" before the final answer — but that slowness comes with greater transparency in its reasoning.

Get Started Now

You don't need to choose just one. Smart users leverage both models — each for what it does best.

Start by trying DeepSeek's free tier for coding and technical tasks. Use ChatGPT for Arabic content and creative tasks. And if you want to explore AI Basics first, that will help you understand the differences more deeply.

The important thing is to start — because those who don't use AI tools today will find themselves falling behind tomorrow.
