Claude Sonnet 3.5 VS ChatGPT 4o
The landscape of Large Language Models (LLMs) is evolving at a breakneck pace. This comprehensive guide provides a deep-dive comparison between two of the industry's most formidable titans: OpenAI's ChatGPT-4o and Anthropic's Claude 3.5 Sonnet. By examining raw technical specifications, industry-standard benchmarks, and real-world logic tests, we aim to determine which model holds the crown for your specific development or business needs.
Technical Benchmarks and Specifications
In the realm of high-performance AI, raw specs often dictate the ceiling of a model's utility. Below is a detailed breakdown based on the original data from Benchmarks and specs.
| Specification | ChatGPT-4o | Claude 3.5 Sonnet |
|---|---|---|
| Context Window | 128K Tokens | 200K Tokens |
| Knowledge Cutoff | October 2023 | April 2024 |
| Release Date | May 13, 2024 | June 21, 2024 |
| Tokens Per Second | ~100 t/s | ~80 t/s |
💡 Key Takeaway: Claude 3.5 Sonnet takes an early lead for power users requiring long-context handling (200K) and more recent data. However, GPT-4o remains the king of speed for real-time applications.
Standardized Performance Benchmarks
Benchmarks provide a standardized way to measure "intelligence" across various domains such as coding, math, and reasoning.
| Benchmark Category | ChatGPT-4o (%) | Claude 3.5 Sonnet (%) |
|---|---|---|
| MMLU (General Knowledge) | 88.7 | 88.7 |
| GPQA (Graduate Reasoning) | 53.6 | 59.4 |
| HumanEval (Coding) | 90.2 | 92.0 |
| GSM8K (Grade School Math) | 90.5 | 96.4 |
Real-World Logic and Creativity Tests
Numbers on a chart are one thing, but how do these models perform when faced with human nuance and tricky logic?
🧩 Logic Puzzle: The Siblings Challenge
"Alice has 2 sisters and 3 brothers. How many sisters does Alice's brother have?"
Analysis: Claude demonstrates superior spatial and relational reasoning by including Alice in the count of sisters for her brother.
💻 Coding Performance: Snake & Pacman
While both models can generate functional Python code for simple games, GPT-4o showed a slight edge in "first-shot" perfection for complex UI features like difficulty menus and pause functions. Claude 3.5 remains highly capable but occasionally required minor debugging in specialized game logic (e.g., ghost pathfinding in Pacman).
Vision and Multimodal Nuance
In the "Upside Down Cup" trick question, ChatGPT-4o demonstrated an impressive grasp of physical common sense. When asked what happens to marbles in a cup that is turned upside down, GPT-4o correctly identified that they would fall out, whereas older models or less sophisticated reasoning engines often hallucinate that the marbles stay inside.
GPT-4o Vision Strength: High understanding of physical interaction and nuance.
API Pricing Strategy
For developers building on top of these models via providers like AICC API, cost is a major factor.
Per 1M Tokens (Estimated):
- Claude 3.5 Sonnet: Input: $3.00 | Output: $15.00
- ChatGPT-4o: Input: $5.00 | Output: $15.00
Note: Claude 3.5 Sonnet offers significantly lower input costs, making it ideal for large-scale data processing or RAG (Retrieval-Augmented Generation) applications.
Final Verdict
Choosing between ChatGPT-4o and Claude 3.5 Sonnet depends on your specific use case:
- Choose Claude 3.5 Sonnet if you need high-level logical reasoning, superior coding assistance, or have a tight budget for large input volumes.
- Choose ChatGPT-4o if you require the fastest response times, advanced voice/multimodal features, or highly creative, conversational outputs.
Frequently Asked Questions (FAQ)
1. Which model is better for programming?
