Deep Architectural Overview
Gemini 3.5 Flash integrates thinking budget controls into the Flash architecture. Developers can tune reasoning effort from 0 (instant response) to maximum (deep analytical thinking), matching task complexity on the fly.
Strengths & Considerations
Core Strengths
- Configurable thinking effort levels
- Large 64k token output capacity
- Outstanding price-to-performance ratio
Known Limitations
- Maximum thinking levels increase latency
