Generate images using Gemini

Gemini 2.0 Flash Experimental supports the ability to output text and inline images. This lets you use Gemini to conversationally edit images or generate outputs with interwoven text (for example, generating a blog post with text and images in a single turn). All generated images include a SynthID watermark, and images in Google AI Studio include a visible watermark as well.

Note: Make sure to include responseModalities: ["TEXT", "IMAGE"] in your generation configuration for text and image output with gemini-2.0-flash-exp-image-generation. Image only is not allowed.
