Google: Nano Banana 2 Lite (Gemini 3.1 Flash Lite Image)

The Google Nano Banana 2 Lite (Gemini 3.1 Flash Lite Image) is an AI model capable of processing both text and images with a context length of up to 65,536 tokens and the ability to reason through complex inputs. It supports text-based reasoning but does not offer structured output or integrate tools. Given its current price point-$0.25 per million input tokens and $1.5 per million output tokens-and the lack of independent benchmark coverage, this model is best suited for users who prioritize multi-modal capabilities and need to reason through textual data without requiring structured outputs or tool integrations. While it may not currently have proven performance metrics, its moderate cost makes it a viable option for those willing to explore its features before extensive evaluation.
