Chain-of-Thought Reasoning
Nano Banana 2 features a configurable Thinking Level. By increasing the reasoning depth, the model performs a multi-step internal analysis of your prompt before rendering. This significantly improves spatial logic, ensuring that objects are placed exactly where you requested and that complex, multi-layered descriptions are followed to the letter.
