Hi,
So I have been using the default gemini-2.5-flash for some image generation. I now have it configured as and AI task. This works fine, but I want to move to the newer models such as nano banana. How can I do that?
When I add another AI task service with the nano-banana-pro-preview model it does not show up as a viable option when I am trying the generate image action un developer tools. However, when I choose the generate data action, it shows up as a an option. Is there a way to rectify this?

Hi Teex, you can set the default by entering settings>voice assistant>select your ai>cogwheel>uncheck recommended model settings>submit>select your banana

#

or from settings>devices/services>select gemini>configure

#

do update and backup haos first though

Sorry for the slow response. So I went to the Gemini service. There I have the attached defined.
If I simply go into the one called Google AI Task and uncheck the recommended model, then change it to nano banana. I get an error message saying the model does not support generating images when I try to run it.
