Nano Banana 2 (Gemini 3.1 Flash Image)

Google's lightweight multimodal model for generating and understanding images alongside text, built on the Gemini 3.1 Flash architecture with a 131K token context window.

Strengths

Handles both image and text inputs efficiently, with a larger context window than its Lite variant and predecessor Nano Banana.

Best for

Applications that need multimodal capabilities — processing images and text together — at a lightweight price point without the overhead of larger models.

Limitations

Designed for efficiency rather than frontier reasoning; the Nano Banana Lite variant offers a smaller context window if you need even lighter resource usage.
