ChatGPT vs Claude vs Gemini: 2025 Comparison
We tested ChatGPT-4, Claude 3.5 Sonnet, and Google Gemini Pro across 50 real business tasks to determine which AI model delivers the best results for different use cases. Here are the findings.
The Testing Methodology
We evaluated each model across five key business categories:

- Data analysis (spreadsheet analysis, trend identification)
- Customer support (FAQ generation, ticket responses)
- Code generation (Python scripts, API integrations)
- Strategic thinking (business planning, problem-solving)
📊 Key Finding:
There is no single "best" model. Each excels in different areas, and most businesses will benefit from using 2-3 models strategically depending on the task.
