Poe API

Nano-Banana

Google DeepMind's Nano Banana (i.e. Gemini 2.5 Flash Image model) offers image generation and editing capabilities, state-of-the-art performance in photo-realistic multi-turn edits at exceptional speeds. Supports a maximum input context of 32k tokens. Optional parameters: Set aspect ratio. Select from (1:1, 2:3, 3:2, 3:4, 4:3, 4:5, 5:4, 9:16, 16:9, 21:9). It is set to 16:9 aspect ratio as default. Image only to only generate image output. It is `off` by default Note: Simply enabling image only will not result in an image unless the prompt is phrased specifically for image generation, but it does guarantee that only a single image (or none) will be produced.
