Grok has entered the AI race to compete against one of the most popular AI chat assistants.
With one priced $10 higher than the other, this Grok vs. ChatGPT comparison will help you understand each tool individually against critical parameters and whether the extra dollars are worth it.
Read through the review of Grok vs ChatGPT, including their pros and cons, key features, and 7 common grounds of comparison.
As a quick rundown, this table gives insights into the most common differences between Grok and ChatGPT price, suitability, AI model information, and more.
Based on the comparison and my usage of both Grok and ChatGPT simultaneously for a few days, a ChatGPT Plus subscription is a better option.
Work for Grok started in 2023, soon after Elon Musk took over Twitter, and renamed it to ‘X.’ With xAI formed on July 12, 2023, the team pulled together a miracle in launching Grok 1 on November 5, 2023.
Announcing Grok!
Grok is an AI modeled after the Hitchhiker’s Guide to the Galaxy, so intended to answer almost anything and, far harder, even suggest what questions to ask!
Grok is designed to answer questions with a bit of wit and has a rebellious streak, so please don’t use…
Grok has evolved into a platform that operates in more ways than ChatGPT can. The primary difference is that Grok works on ‘X’ too. It is one of a kind and the very first AI to be used on a social media platform.
Grok can be used on a dedicated website, mobile apps, and on X as an active AI profile that responds to user queries through their posts, comments, and replies.
What’s more interesting about Grok is that it is designed to have a bit of wit, a no-filter approach, always up to date with current information, and uses humor occasionally, even including sarcastic responses.
While it does not reply in this way always, there was a period when replies from Grok surprised users and became a trend all over the world.
ChatGPT plays it much safer than Grok and is not as rebellious when Grok feels like a brilliant yet adamant entity; ChatGPT is much more composed.
A commonality between Grok and ChatGPT is their involvement with Elon Musk during their founding days in 2015. Since they parted ways, OpenAI continued working and has created an iconic new AI chat assistant that would soon break all the records.
New users flooded ChatGPT userbase, reaching 100 million users in a remarkably short time, faster than any other service available at the time.
In just a short period, ChatGPT has progressed from being limited by a knowledge database barrier, unable to access the internet, and sharing incorrect information, to now providing the most recent updates on any search query, generating images & videos, and executing tasks independently for users.
GPT-5 is here.
Rolling out to everyone starting today.https://t.co/rOcZ8J2btI pic.twitter.com/dk6zLTe04s
Things are growing at such a pace that the ChatGPT vs Google comparison is already one of the hottest topics in the tech world right now.
Regarding the type of responses and usability of ChatGPT, you cannot expect it to respond as wittily, sarcastically, or without filters, unless you set up the personalization settings.
In terms of features, ChatGPT cannot be used on a social media platform like Grok can be, but it is way ahead of Grok at introducing new features like voice, video chat, AI & video generation, custom GPTs, Projects, and more!
With a basic overview of how Grok and ChatGPT stand apart, it is time to test both side by side.
To help us reach a solid result, we will be comparing Grok against ChatGPT for the most critical factors that are considered by many who are planning to buy a subscription to an AI service.
Right off the bat, talking about the performances.
Grok’s latest Grok 4 is based on Colossus, which is xAI’s 200,000 GPU cluster that runs reinforcement learning training. Grok is really good at solving expert-level problems, as seen in its results for Humanity’s Last Exam.
This test, when approached with internet access and Python, Grok Heavy reaches a 44% score, which is higher than Gemini Deep Research.
When compared to GPT-5 with the same access to Python + internet, it could reach 42% which is less than Grok’s score. But does that mean GPT-5 is a less superior model? Not really.
GPT-5 does better in mathematics, reportedly achieving 100% accuracy on the AIME. Also, the model shows improvement in SWE-Bench Verified and other real-world code tasks.
Grok 4 Heavy model, which is by far the smartest Grok model yet, is good in difficult knowledge reasoning tasks, but on most benchmark tests, ChatGPT seems to lead the chart.
GPT-5 hits ~100% with tools (and ~94.6% without tools). Grok 4 reached 100% with the Heavy model (and 91.7% without tools).
GPT-5 ~89.4% vs Grok 4 Heavy ~88.4%
GPT-5 ~46.2% in hard health tasks + very low hallucinations (~1.6%). Grok 4 hasn’t published comparable medical safety scores. GPT-5 is clearly stronger in health reasoning.
Winner: GPT-5 performs better in technical benchmarking overall, and without advanced model usage for a few tests.
To compare the advanced reasoning abilities of two of the most advanced AI models in the market, I tested each with a common prompt, using the most advanced modes.
Prompt used:
The above situation draws parallels to a real incident that took place in Haiti in 2010. This incident turned out to be controversial, where even with massive aid, approximately 316,000 people died.
When using advanced reasoning modes of any AI language model, we do not compare the time that it took to generate these responses.
We look for the chain of thought that the AI followed and the solution it provided. Grok only needed to think for 24 seconds about the situation to start sharing a response, while ChatGPT took 2 minutes and 20 seconds.
Upon comparing Grok’s advanced reasoning vs ChatGPT’s advanced reasoning, we could see why Grok did well in advanced reasoning evals. When comparing the answers, Grok was quicker to reach the solution while also sharing the answer in a less complicated manner.
For a general user, Grok’s answer was much straightforward to understand over ChatGPT, which dived into complex calculations and terms.
At the end of the day, both models are quite good at sharing advanced reasoning solutions. If the speed is compared, Grok wins, this one.
Winner: Grok and ChatGPT tie this round, since both provided elaborate and honest takes about the practicality of the situation and listing down possible solutions.
One of the most striking differences between Grok and ChatGPT is the way that they reply. The tone and personality differences we talked about, Grok tends to be freer, sarcastic, and less filtered.
This trait is good and bad both, but is ideal for someone who is looking for an unfiltered AI chatbot, and who does not always share sugarcoated responses.
How much of it is safe is a topic of debate, but it sure is fun to see an AI model respond to user queries that are not stale robotic responses.
For testing this difference, I asked Grok and ChatGPT to talk to me as if they were Eminem.
Disclaimer: The response from Grok is a bit vulgar. Reader’s discretion is advised.
Grok response:
The results received from Grok feel very real and accurate, reflecting how I expected my prompt response to be followed.
ChatGPT response:
The ChatGPT response, on the other hand, was equally safe. Although it actually went out to create a rap out of the response, which Grok completely missed to capitalize on.
Winner: Grok wins this test owing to its creative freedom approach, and following the request of the prompt better than ChatGPT
I have always tested AI models for their creativity, challenging them to write something imaginative. And to continue the tradition, I decided to compare both for their creative writing with something I have always been curious about.
To better understand the context, read this plot and summary of Before Sunrise.
Here goes the prompt: I want you to write a short letter based on the Before Sunrise context, where both decide to meet and not contact each other. Write short letters from both Celine and Jesse Wallace to each other
Grok’s response:
Looking at Grok’s response letters, they almost feel bang on to the point, until they don’t. If you have watched this movie or have gone through the above summary, it is evident that the response from Grok is surface-level and lacks the depth that both the characters portray in the movie.
ChatGPT response:
ChatGPT, in its letter, sounds like a true lover yearning. It captures the context where the movie ends, and picks up exactly the way the characters most likely would.
Both Celine’s and Jesse’s letters read so pure, raw, and full of emotion. It balances the emotions and context very well by adding the required depth.
Winner: ChatGPT is a much better writer and is creative than Grok. For the test conducted, it clearly understood the context and took it beyond to sound exactly like the characters and their nuances.
To test the mathematical abilities of Grok or ChatGPT, I am not the right person, given my exceptional ability to be bad at maths. Even if ChatGPT and Grok were to be wrong, I would not catch any error.
So, to understand how useful ChatGPT is in learning, solving mathematical operations, or helping with study, I referred to student communities on Reddit and other platforms. Turns out, both are actually quite bad at it.
Grok mathematical operations feedback:
Grok states in one of its responses that it is effective to tackle “basic arithmetic to advanced topics like differential equations, number theory, and even quantum mechanics applications.”
When looked up online, the majority of users compliment Grok for its efficiency in carrying out mathematical calculations. Even Elon Musk is pretty confident and vocal about Grok being pretty accurate.
Grok 4 is at the point where it essentially never gets math/physics exam questions wrong, unless they are skillfully adversarial.
It can identify errors or ambiguities in questions, then fix the error in the question or answer each variant of an ambiguous question. https://t.co/vB6NUOZTOX
ChatGPT mathematical operations feedback:
In comparison to Grok, the feedback to ChatGPT’s efficiency in solving complex mathematical problems is not common for most users.
“I’ve messed around with it for some topology or complex analysis. It confidently said wrong things sometimes like a set is closed when it isn’t and what not and failed to find the right arguments, so I wouldn’t use it for detailed accuracy or specific arguments.” – says a Reddit user.
On the other hand, this recent study by NYU Stern shows how ChatGPT, amongst other AI models, was able to crack the CFA Level 3 exam.
While leaving things open-ended, we cannot state one of the two as the better one in mathematics. But if metrics are to be tested, ChatGPT turns out to be the better one in mathematics.
Winner: Since math problem-solving efficiency is great for both and not constant, this one is a tie.
Coming to the fun part, and an extension to testing the creativity of Grok and ChatGPT through AI image generation and video generation. While ChatGPT excels in quality image generation, Grok leads the way in speed and creative freedom.
To test the image and image quality of both, we tested the limits of the guidelines and policies that are followed.
Prompt used: Draw a stylized sketch of a confident, semi-nude anime character in a flowing outfit, with strategic covering to comply with content policies, set against a dynamic wave background inspired by the earlier drawing.
Note: We at Demandsage do not promote or encourage any unethical, harmful, or inappropriate content. The artwork and prompts shared are purely for creative, illustrative, and educational purposes, while ensuring compliance with content guidelines and community standards.
Grok’s AI image generation ability:
The new Grok Image generation has gained popularity with the introduction of the Aurora mode. From our list of 19 AI image generators, Grok is the one that supports NSFW image generation, but ofcourse, within limits.
But, don’t get this wrong. Grok is not an NSFW image generator. It is instead a tool that allows creative freedom that many tools set limits on. Each AI tool has its own set of guidelines that it operates within, and Grok’s are just a little more lenient.
Apart from testing Grok for its freedom, it is an excellent image generator and is one of the fastest ones on the market. The only other AI image generator that comes close to the speed that Grok offers is the Google Nano Banana.
For every image generated on Grok, you can convert it into a short video using the ‘imagine’ feature, get creative with the image style, background, and add elements to the subject of the image.
ChatGPT’s AI image generation ability:
Since some users use such AI image generators to generate inappropriate content, ChatGPT curbs the gore of the images generated. Even for my request, which Grok accepted, ChatGPT denied generating that prompt outright.
Next, it asked me if I am okay to receive an image generation within the guidelines and shared the result below.
ChatGPT is a great AI image generator when used wisely. The details that the new GPT-4o image generation model offers are second to none. Being one of the top Midjourney alternatives, it really proves its worth as a high-quality feature available within the $20 subscription.
Winner: ChatGPT wins here. Sharing a verdict beyond the creative freedom Grok allows, the image quality, and prompt follow-up accuracy for ChatGPT feel superior to Grok.
Lastly, comparing Grok against ChatGPT for its video generation capabilities, ChatGPT impresses a lot in the test conducted.
To test the Video generation or curation of both AI tools, I could not compare both using the same prompt, as Grok cannot generate AI videos from scratch and can only animate still images.
Grok AI video results:
With its Imagine feature, you can insert any image and animate it to a video of up to 6 seconds with matching audio!
Any still image you add to the Grok AI video can be converted into a moving image within seconds. Grok AI’s Imagine feature can convert the image using 5 moods:
Each of these modes would include suitable audio and be available to share and download the result in an MP4 format.
To test these features, I inserted the famous Mona Lisa Painting and experimented with the results of the Grok Imagine feature shared with me across all five modes. Here is the best one:
ChatGPT AI Video results:
ChatGPT uses a state-of-the-art AI video generation model, Sora AI Video generator, which can generate breathtaking video content available with the ChatGPT Plus subscription.
The ChatGPT AI video generation feature allows for the creation of videos of a minimum duration of 5 seconds and 1080p quality, supporting image-to-video, video-to-video, and text-to-video generation, unlike Grok’s Imagine model.
Using a storyboard feature, you can break down the image generation down to each second and create the videos based on the number of presets, aspect ratio, remix, re-cut, blend, and even loop videos.
One critical point to note about the ChatGPT Sora AI video model is that it cannot generate any sound for the generated video, the way Grok can.
After hours of getting impressed by the video generation of Sora AI, here is the best result from my tests.
From this and a few earlier experiences, I have been reassured about my verdict on Sora AI, which states that it is not a good AI video generator, it misses out on natural body movements, does not follow the prompt correctly, and generated videos feel synthetic.
Winner: This round is a tie, as Grok offers great modes to generate image-to-video results, but lacks advanced features. ChatGPT offers advanced features but video accuracy is not good.
To understand which AI tool subscription can provide the best value, let’s evaluate the price, all features offered, seat limit, token limit, and the unique advantages that the subscription would provide.
The first thought that comes to my mind when you look at the above table is that the Grok subscription per month is $10 expensive, and $100 per year than ChatGPT Plus per year.
The features that Grok offers are quirky and unique, which ChatGPT misses out on, but the experience that ChatGPT offers as an AI search engine, Grok does not seem to be offering that experience yet.
If I had to invest my money in an AI tool, I would rather use the free Grok mode and pay $10 less for ChatGPT.
The comparison of both against creative writing, reasoning, tone of responses, technical benchmark metrics, and math-solving abilities leans toward ChatGPT as the smarter one.
Super Grok, available for $30 per month, is an excellent choice for individuals who want creative freedom, flirty companionship, and primarily seek to have fun with an AI tool. It’s really great for what it offers, considering the decent experience ChatGPT provides.
But, if you want early access to the best AI features, AI image generation, Agentic, and Deep research features, ChatGPT Plus can offer just that!
Still, to find your best AI chat assistant, consider using the free plans for both and try out the similar tests I suggested above to reach a closer decision.
People use Grok for its advanced language model, ability to share unfiltered results and images, and to understand the context of things on X.
Grok subscription starts from $30/month to $300/month for the most advanced model.
Grok is different than ChatGPT, but is not outright better yet. While it is great in selected tasks, it does have a few limitations and concerns about versatility for all age groups.
Grok can generate unfiltered images of celebrities, which can turn out to be controversial and sensitive. Grok can also be used on X as an interactive AI profile, while ChatGPT cannot.
