AI Face-Off: DeepSeek R1 vs. OpenAI’s o1 — Which One is Smarter?

Ever wondered how different AI models think? What if we put two of them head-to-head in a battle of logic, creativity, and problem-solving? Today, we’re putting DeepSeek R1 and OpenAI’s o1 to the test — who will come out on top?

AI models “think” differently, process data uniquely, and sometimes, even arrive at completely opposite conclusions. So, what happens when we put DeepSeek R1 against OpenAI’s o1 in a direct test of reasoning, problem-solving, and creativity?

In this publication, we compare how DeepSeek R1 and OpenAI’s O1 tackle reasoning challenges using identical prompts. While this article focuses on a single example, you can explore additional comparisons and insights in our full blog, available here.

The Comparative Experiment — DeepSeek R1 and OpenAI’s o1

Let’s see how two AI models — DeepSeek R1 and OpenAI’s o1 — tackle various challenges. For each prompt, the exact instructions along with the responses from both models are shared, and the differences are in detail. Let’s dive in!

Prompt #1: Logical Deduction

Prompt
If all mammals are warm-blooded and dolphins are mammals, what can we conclude about dolphins?

DeepSeek R1 Reasoning & Response

Using deductive reasoning (specifically a syllogism), we can conclude:

Key Logical Steps:

1. Categorical Syllogism:

The argument follows the structure:
All A (mammals) are B (warm-blooded).
C (dolphins) is an A (mammal).
Therefore, C (dolphins) is B (warm-blooded).

1. No Exceptions:

The first premise states “all” mammals, leaving no room for exceptions.
The second premise definitively categorizes dolphins as mammals.

1. Inheritance of Traits:

If a category (mammals) has a universal property (warm-bloodedness), every member of that category inherits the property.

Why This Works:

The logic is valid (the conclusion follows necessarily from the premises).
If the premises are true (as stated), the conclusion must be true.
Thus, we can definitively conclude — Dolphins are warm-blooded. 🐬

o1 Response

If all mammals are warm-blooded and dolphins are mammals, we can conclude that dolphins are warm-blooded. This follows the basic logical principle known as modus ponens:

All mammals are warm-blooded.
Dolphins are mammals.
Therefore, dolphins are warm-blooded.

Final Thoughts

DeepSeek R1 walks you through the entire thought process, making sure you understand every logical step. o1, on the other hand, keeps it short and to the point — perfect for those who just want the answer, no fluff. Which approach do you prefer? Do you like the detailed explanations, or do you just want the answer?

Okay, they can think logically, but can they build? These AI minds aren’t just about abstract logic — they need to be practical too.
