Introduction

This video explores Google's Gemini 2.5 Flash, a hybrid reasoning model allowing users to toggle "thinking" on or off. The presenter tests the model's performance in various domains (clinical notes, coding, physics, math) comparing results with and without the "thinking" mode enabled to assess the impact of reasoning on accuracy and speed.

Key Takeaways

• Thinking vs. Non-Thinking Modes: Gemini 2.5 Flash offers both "thinking" and "non-thinking" modes, allowing users to control the model's reasoning process. The "thinking" mode may improve accuracy in complex tasks like clinical diagnosis and physical reasoning but often at the cost of increased processing time.
• Variable Performance: The impact of the "thinking" mode varied across different tasks. In some cases, it significantly improved accuracy (e.g., clinical diagnosis), while in others, it made little difference or even yielded worse results than the "non-thinking" mode (e.g., certain math problems, coding).
• Speed vs. Accuracy Trade-off: Enabling "thinking" generally increased processing time. In some instances, the "non-thinking" mode provided faster and equally accurate solutions.
• Experimentation Necessary: The presenter suggests that users experiment with both modes to determine which best suits their specific needs and prompts, considering the trade-off between speed and accuracy.
• Thinking Budget: Gemini 2.5 Flash automatically adjusts a "thinking budget" unless specified by the user. Optimizing this budget might further enhance performance.
