High EQ, advanced reasoning
Grok, developed by xAI, is also a generative AI chatbot, available for handling different missions, and its latest version - Grok 3 supports advanced reasoning ability, real-time data integration and multimodal input processing eg. text, code and images.
How Does Grok Compare to ChatGPT?
ChatGPT and Grok are rapidly accelerating their update cycles to offer better AI chat online experiences. To figure out their performances, we tested four common user needs, including ChatGPT vs Grok price, question-answering task handling, coding, creative writing, and image generation.
Check out the key takeaways in the chart below - or scroll on to dive deeper into the full details.
High quality, matches prompt, multiple styles (Anime, Cyberpunk, etc.)

Core Performance
Here, we will evaluate the chatbot's most essential generative capabilities, focusing primarily on response accuracy, text understanding, speed, and efficiency. We used a scientific question prompt: "Concisely state Marie Curie's top 3 verified scientific achievements (each in 20 words) with her Nobel year, excluding personal details", and let's see their core performance below.
We can observe that ChatGPT accurately understood the instructions and provided a response meeting all requirements within approximately 3.2 seconds. Furthermore, it cited highly authoritative and reliable sources, such as the Atomic Heritage Foundation or official government web pages.
Grok delivers answers a little bit faster than ChatGPT and adeptly interprets the question to provide a relevant response. However, since its underlying source data is not disclosed, the accuracy remains uncertain for us to double check. Alternatively, using Grok's DeepSearch mode reveals its data sources, but it takes longer time to generate a detailed, traceable answer.

In ChatGPT vs Grok 3 core performance test with this prompt, ChatGPT delivers more accurate, reliable, and well-supported responses.
Coding Performance
Then, to test ChatGPT vs Grok for coding, we establish a premise: assume the user has absolutely no coding knowledge and no coding tools installed on their device. Under these conditions, ask both chatbots to provide a simple, pure HTML code example that creates a webpage with a button. When the user clicks the button, the page text should change from "HELLO" to "You clicked me". Additionally, they should clearly explain the code and how to test it online.
ChatGPT took around 13 seconds to generate the code, a clear explanation, and a step by step instruction on how to test the code online for free. The test results were flawless. The illustration of the code was very easy to understand and user friendly, even for someone with absolutely no prior coding knowledge!
In comparison, Grok spent a little bit longer time, and not only did it generate the requested code and explanation, but it also let you run the code directly within the interface and see the result. Even though it was slower, for the coding challenge, from the perspective of a non-experienced rookie, this unique feature gives more credit for its coding performance.
Creative Writing Performance
Next, let's see ChatGPT vs Grok for wiring! We also gave a prompt about creating a story of a musician who loses the ability to see sounds within 250 words, including some writing requirements to test their abilities.
We can see that both pieces are brilliantly written within a very short time, each utilizing different sensory expressions while fully meeting the creative requirements.
Grok's story about Elara captures emotional layers through sensory detail, and instead of the cliché plot - ability restoration, it transitions into experiencing music in a new way.
ChatGPT's Mira story employs even richer sensory descriptions, and the return of her ability through placing the metronome core into the jar brings a fresh twist.
Therefore, in this aspect, they all offer great answers. However, the article appreciation is a personal thing, so every individual might have different views.
Image Generating Performance
Last performance match is ChatGPT vs Grok image generator. We set a detailed prompt: "A joyful brown puppy chewing a bright red ball on a sunny beach, with wet sand on its paws, turquoise ocean waves, and golden sunset light - untethered and text-free", and test if they can generate the picture exactly according to the user's expression.
Although Grok generated two images in a short time, both pictures generated didn't fully match the prompt. ChatGPT took a longer time, but might have had a better understanding of the prompt and delivered an adorable dog image in Anime style. It also provides other image styles like Cyberpunk, Photo Shoot, etc, for users. Despite the speed difference, ChatGPT might have better performance of AI image generator based on quality. But, we must acknowledge that the speed and quality of image generation still depend on the internet connection and the given prompt.
Which Is Better, Grok or ChatGPT?
Based on the comparison across several aspects, we can conclude that ChatGPT generally has a slight edge in core functionality, coding, writing, and image generation. However, Grok also offers an impressive code execution feature and amazing writing potential. If you're looking for a well-rounded and stable overall experience, ChatGPT is a great choice.
