In a practical test, Google Gemini 3.6 Flash and OpenAI GPT-5.6 Sol were compared by giving both AI models access to a user’s digital life. The data included calendar entries, messages, receipts, photos, and notes. While Gemini mainly summarized the available information, GPT demonstrated stronger reasoning capabilities. It identified conflicts, calculated expenses, interpreted notes, and created a practical weekly plan.
The test highlighted a key difference between the two systems. Gemini provided condensed information, whereas GPT-5.6 transformed data into concrete recommendations. The comparison suggests that future AI assistants will be judged less by benchmarks and more by their ability to effectively solve real-world problems.
