Grok 3 vs DeepSeek R1: Which is Better?

Just months ago, DeepSeek's V3, R1, and Janus models made waves in the AI community. Now, Elon Musk's Grok 3 has entered the arena, boasting the title of "smartest AI on Earth." Initial benchmarks from xAI were impressive, showing Grok 3 surpassing competitors in various tests. But how does it perform on everyday tasks? Is the $40 X Premium subscription worth it? This article compares Grok 3 and DeepSeek R1 across five diverse prompts to find out.

Table of Contents:

• Task 1: Python Code Generation
• Task 2: Web Search
• Task 3: Basic HTML Animation
• Task 4: Image Analysis (Chess)
• Task 5: Logical Reasoning (Zebra Puzzle)
• Grok 3 vs. DeepSeek R1: Results
• Conclusion

Task 1: Python Code Generation

Prompt: "Write a Python function to generate a random maze using depth-first search and visualize it using Matplotlib."

(See code and image comparisons in original text. Maintain original formatting and image.)

Observation: DeepSeek R1 produced a clear, well-structured maze. Grok 3's output was pixelated and less defined, despite using DFS.

Verdict: Grok 3 ❌ DeepSeek R1 ✅

Task 2: Web Search

(Note: DeepSeek R1 used its own search function for this task.)

Prompt: "What are the latest advancements in nuclear fusion technology as of 2025? Format: List of advancements source."

(Maintain original video embed.)

Observation: DeepSeek R1 provided verifiable sources for each claim, offering a more comprehensive and trustworthy response. Grok 3 lacked direct source links, relying on less reliable sources like X (formerly Twitter).

Verdict: Grok 3 ❌ DeepSeek R1 ✅

Task 3: Basic HTML Animation

Prompt: "Create HTML CSS code for a red ball rotating continuously inside a square."

(Maintain original code snippets and video embed.)

Observation: Grok 3 struggled to generate the correct code. DeepSeek R1, while slower, provided accurate and functional code.

Verdict: Grok 3 ❌ DeepSeek R1 ✅

Task 4: Image Analysis (Chess)

Prompt: "Analyze this chessboard position. Suggest the best move for White to checkmate Black and explain the reasoning."

(Maintain original image comparisons.)

Observation: Both models failed to correctly identify the checkmate.

Verdict: Grok 3 ❌ DeepSeek R1 ❌

Task 5: Logical Reasoning (Zebra Puzzle)

Prompt: "Solve this zebra puzzle. Give me the output in a table."

(Maintain original image comparisons.)

Observation: DeepSeek R1 correctly solved the puzzle; Grok 3 did not.

Verdict: Grok 3 ❌ DeepSeek R1 ✅

Grok 3 vs. DeepSeek R1: Results

(Maintain original table.)

Conclusion

Grok 3's marketing claims of being the "smartest AI" were not supported by this real-world testing. DeepSeek R1 consistently outperformed Grok 3 in accuracy, structure, and verifiability. While Grok 3 showed potential in some areas, its weaknesses in logical reasoning and complex problem-solving are significant. Whether future updates will improve Grok 3 remains to be seen. The results suggest xAI needs substantial improvements to its training methods.
