Grok 3 vs ChatGPT vs DeepSeek: Quick Comparison

Grok 3 vs ChatGPT vs DeepSeek: Detailed Comparison

To help our readers assess the performance and efficiency of Grok 3 over its competitors, we have this detailed comparison covering key parameters.?

1. Reasoning and Problem-Solving

This is about how well these AIs can think and solve tough problems—like math, science, or coding. Let’s break it down with some numbers.

• Math (AIME 2025): In the benchmark math test, Grok 3 got 93.3% right, which is awesome! ChatGPT’s best model, called GPT-o1, got 79%. DeepSeek’s R1 scored 79.8%, just a tiny bit better than ChatGPT but still behind Grok 3.?
• Science (GPQA): This test checks how well the AIs understand science stuff, like things experts might know. Grok 3 scored 84.6%, beating ChatGPT’s GPT-o1, which got 78%. DeepSeek R1 got around 68% in a similar test.
• Coding (LiveCodeBench): Grok 3 scored 79.4%, better than ChatGPT’s GPT-o1, which got 72.9%. DeepSeek’s R1 scored about 57.2% on this test, so it’s not as good at coding.?

Winner: Grok 3. It’s the best at solving math, science, and coding problems. ChatGPT is close behind, but DeepSeek struggles more in these areas.

2. Speed and Efficiency

Speed matters a lot—who wants to wait forever for an answer? Efficiency is about how fast they work without using too much power or time.

• Grok 3: This AI is super fast. It’s built with tons of power—200,000 GPUs (computer chips) help it run quickly. People say it answers questions in seconds, like writing a Python script or searching the web.
• ChatGPT: ChatGPT is fast too, but not as lightning-quick as Grok 3. It takes a little longer for tough questions because it thinks deeply to give polished answers.?
• DeepSeek: DeepSeek is slower than the others. It’s built to save money (trained on just 2,048 chips), but that means it can’t keep up in speed. Sometimes its servers even crash when too many people use it, which makes it less reliable.

Winner: Grok 3. It’s the fastest and doesn’t slow down, even with hard tasks. ChatGPT is good, but DeepSeek lags behind.

3. Content Creation

Content creation is about writing stuff—like stories, articles, or posts. Let’s see how they do.

• Grok 3: Grok 3 is great at writing natural, easy-to-read text. People say it’s the best at making content sound human and clear. It can write fast too, which is handy for quick projects. It’s not perfect at super creative stuff like funny stories, but it’s solid for most writing.
• ChatGPT: It’s been around longer and writes really well—stories, essays, even poems. It’s smooth and can sound smart or fun, depending on what you need. It’s the go-to for creative writing or long articles.
• DeepSeek: DeepSeek isn’t as good at this. It can write okay, especially technical stuff like math explanations, but it’s not as smooth or lively as the others. It’s more about facts than fancy words.

Winner: ChatGPT. It’s the best for writing all kinds of content. Grok 3 is close to the simple, natural text.

4. Real-Time Data Access

This is about getting fresh info from the internet or places like X right now, not just old stuff they learned.

• Grok 3:. It can search the web and pull info from X instantly with its DeepSearch tool.?
• ChatGPT: ChatGPT can search the web with some models (like GPT-4o), but it’s not as quick or connected as Grok 3. Its reasoning models (like o1) stick to old data they were trained on.
• DeepSeek: DeepSeek doesn’t do this well. It only knows what it was trained on—no live web or X access. If you ask about today’s news, it can’t help much.

Winner: Grok 3. It’s the only one that grabs real-time info fast and well. ChatGPT tries, but DeepSeek can’t keep up.

5. Modes

Modes are like special settings these AIs can switch to for different tasks.

• Grok 3: It has modes like Think Mode (which shows how it solves problems step by step), Big Brain Mode (which uses more power for tough tasks), and DeepSearch (which finds fresh info).?
• ChatGPT: It has a couple of modes too, like Search (looks online) and Reason (thinks deeply). But it’s not as clear or switchable as Grok 3’s modes.?
• DeepSeek: DeepSeek has a “Deep Think” mode for step-by-step reasoning, which is nice for math or logic. But that’s it—no extra options like searching or boosting power.

Winner: Grok 3. Its modes give you more control and variety. ChatGPT and DeepSeek have fewer tricks up their sleeves.

6. Pricing

How much do they cost? Let’s look at the options.

• Grok 3: You need an X Premium+ subscription, which costs $50 a month in the U.S. (as of February 2025). There’s talk of a SuperGrok plan for $30 a month or $300 a year with unlimited use, but it’s not out yet.?
• ChatGPT: ChatGPT has a free version that’s pretty good. ChatGPT Plus is $20 a month for faster answers and better models (like GPT-4o). There’s also a Pro plan for $200 a month.
• DeepSeek: DeepSeek is mostly free to use online, with a limit of 50 messages a day in its “Deep Think” mode. Its API (for developers) is cheap, too—way less than others.?

Winner: DeepSeek. It’s free or super cheap. ChatGPT has a free option and affordable plans, while Grok 3 is pricier and locked to X.

Conclusion

After looking at Grok 3 vs ChatGPT vs DeepSeek, it’s clear they each have their own strengths. Your choice depends on what you need most!

Grok 3 stands out as the top performer for reasoning—scoring 93.3% in math, 84.6% in science, and 79.4% in coding. It’s lightning-fast and pulls real-time info from the web and X.

ChatGPT shines in content creation, writing smooth and creative text for stories, articles, or anything you need. It’s versatile, with a free version that’s solid and paid plans.

DeepSeek keeps things simple and cheap—mostly free with a 50-message limit daily. It’s decent at reasoning (79.8% in math) and great for technical tasks, but it’s slower and lacks fresh data.
