Grok 3 vs ChatGPT: How X and OpenAI’s chatbots compare

Tech companies and governments are investing billions in AI projects, and new models are entering the market with unique features and improvements. If you have heard of the new large language model Grok 3, you may wonder how it compares to ChatGPT. This article compares Grok 3 and ChatGPT o1.

Grok 3 outperforms ChatGPT in benchmark tests

Benchmark tests show that Grok 3 outperforms ChatGPT. In Math (AIME’25), Grok 3 scores 93.3% compared to OpenAI and its o1 at 79%, proving better mathematical reasoning. In Science (GPQA), Grok 3 scores 84.6% while OpenAI o1 scores 78%, reflecting advanced scientific problem-solving. In Coding (LiveCodeBench), Grok 3 scores 79.4% compared to OpenAI o1 at 72.9% and generates clean, functional code. However, benchmarks differ from user experience, so I started prompting tests.

Grok 3 provides more engaging explanations

Prompt: Explain the difference between a meteor, meteoroid, and meteorite in simple terms, with an example of each.

Both models deliver accurate, user-friendly responses. However, Grok 3 is more informative. ChatGPT briefly explains each term and offers examples but lacks details to engage curious readers. Grok 3 generates a vivid explanation using relatable imagery (such as “space pebble” or “grape-sized chunk”) and a natural flow connecting examples from space, sky, and ground. It adds more context by referencing comets and asteroids as origins, enriching the explanation without overwhelming users.

Grok 3 is faster, but ChatGPT offers more detailed and source-backed news analysis

Prompt: What are the latest updates on recent meetings or interactions between Donald Trump and Volodymyr Zelensky? Summarize key points, reactions, and any geopolitical implications. Provide sources.

Both models reference similar key events but differ in how thoroughly they interpret them. Grok 3 response takes seconds, delivering essential headlines with limited context and concise analysis. ChatGPT response takes about five minutes to explore political dynamics by citing multiple sources, direct quotations, and stakeholder reactions. It adopts a methodical approach, referencing various pieces of evidence and situating them within a broader geopolitical framework.

Grok 3 writes more immersive and creative stories

Prompt: Write a short, engaging bedtime story about a cat who accidentally becomes the mayor of a small town.

Grok 3 creates a slightly more dynamic and immersive version. Grok 3 adds more humor, action, and personality to the tale. Additionally, Grok 3 includes a stronger sense of transformation. Grok 3 also adds absurdity with the election chaos part, giving it an edge in creativity and performing better overall.

ChatGPT offers more thorough instructions

Prompt: Explain how to change a flat tire with simple, step-by-step instructions that a beginner can follow.

ChatGPT and Grok 3 provide clear instructions for changing a flat tire that beginners can follow. ChatGPT is more detailed and includes safety precautions like using wheel wedges to prevent rolling and checking the manual for tools and jack points. It explains the reasoning behind each step, such as tightening lug nuts in a star pattern to ensure even pressure.

Grok 3 is concise and conversational but leaves out details. It compensates with an engaging tone, using phrases like lefty-loosey and righty-tighty to make the process approachable. Ultimately, ChatGPT wins because it offers a detailed, safety-conscious guide.

Comedy feels more natural with Grok 3

Prompt: Explain quantum mechanics as if you’re a stand-up comedian performing for an audience with no science background.

Grok 3 uses a fast-paced, classic comedy club style, while ChatGPT combines humor with structured explanations. Grok 3 excels with punchy delivery and relatable humor. ChatGPT is detailed and explains more concepts, such as superposition and entanglement, with metaphors, but its longer set may overwhelm beginners.

Grok 3 delivers rapid, humorous routines. Its explanations remain lean, occasionally sacrificing depth, but humor is the criterion here. Thus, Grok 3 outperforms ChatGPT with a livelier act.

Grok 3 applies more structured reasoning and logic

Prompt: If a person says, “I always lie,” is the statement true or false?

ChatGPT and Grok 3 tackle the classic Liar Paradox with different approaches. ChatGPT identifies the paradox, explaining that if the statement is true, it contradicts itself by implying the speaker does not always lie. If false, it still leads to inconsistency.

Grok 3 analyzes both possibilities. If true, the statement creates an impossible contradiction (a truth-teller who always lies). If false, it indicates that the speaker lies sometimes. Grok 3 concludes that the statement is false, offering a clear resolution. This makes Grok 3 more practical and satisfying for those seeking a definitive answer.

Test both models to find the best fit for your workflow

While Grok 3 impresses with humor, speed, and structured reasoning, ChatGPT excels in depth and detail. As AI models evolve, both will continue to improve. Try them to determine which suits you best.
