In official benchmarks, GPT o1-preview dominates in reasoning (GPQA: 73.3 vs 62.1) and undergraduate knowledge (MMLU: 90.8 vs 76.4). However, Gemini 2 holds a slight edge in math (MATH: 89.7 vs 85.5) and coding execution.
Real-World Performance Battle
🧩 Logical Reasoning & Riddles
Prompt: Finding patterns in letter-based equations (e.g., aabb = 4, hopq = ?).
GPT o1-preview: Correctly identified the logic of "holes" in typography (e.g., 'a' has 1, 'o' has 1) and reached the answer 3.
Gemini 2: Failed by overcomplicating the logic with case sensitivity and letter pairs, resulting in an incorrect answer.
Winner: GPT o1-preview
🎨 Creative Writing
Prompt: Write a short poem about friendship.
GPT o1-preview: Produced a lyrical, 12-line poem with rich metaphors like "golden thread" and "beacon of serenity."
Gemini 2: Opted for a concise, 6-line poem focusing on intimate gestures like "a knowing glance."
Result: Draw (Style Preference)
💻 Coding & Debugging
In algorithmic challenges like "Minimum Invalid Parentheses," GPT o1-preview provided a perfectly functional BFS solution. Gemini 2 struggled with the logic flow, resulting in non-functional code.
However, in Debugging, Gemini 2 showed superior attention to edge cases (like input validation and try-except blocks), whereas GPT solved only the immediate syntax issues.
Algorithm Winner: GPT | Debugging Winner: Gemini
Pricing & Cost Efficiency
⚠️ Cost Analysis per 1K Tokens:
-
GPT o1-preview: Input $0.015 / Output $0.063
-
Gemini 2.0 Flash: Input $0.0026 / Output $0.0105
Gemini 2 is approximately 6x more affordable than GPT o1-preview, making it the clear choice for high-volume deployments or budget-sensitive projects.
