Settings generation_config response_modalities with IMAGE

Gemini API
1

I want the model to respond to my query with an image response. I am setting the response_modalities within generation_config with IMAGE parameter. The request always fails. If I set it with only TEXT it succeeds. Is the IMAGE parameter supported?

Hi @arpitm, The image parameter is supported, Could you please let me know which model you are using to generate a image for the given query. Please try to use models/gemini-2.0-flash-exp which will work fine. Thank You.

Hi @arpitm

Welcome to the forum.

This depends on the model you chose.

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.

That model has been added very recently only.

Additionally, the model gemini-2.0-flash-exp also works to generate images.

Cheers
