Image Generation

Your assistant can generate images from text descriptions and edit existing images using Google’s Gemini image models.

​

Available models

​

Generating images

Ask your assistant to create an image by describing what you want:

• “Generate a photorealistic golden retriever sitting in a park”
• “Create a minimalist logo for a coffee shop called ‘Brew’”
• “Draw a technical diagram of a microservices architecture”

You can specify aspect ratio and detail level:

• “Generate a 16:9 banner image of a mountain landscape at sunset”
• “Create a square icon for a mobile app”

​

Supported aspect ratios

1:1 · 3:4 · 4:3 · 9:16 · 16:9 · 3:2 · 2:3 · 4:5 · 5:4 · 21:9

​

Editing images

You can also ask your assistant to modify existing images:

• “Remove the background from this image”
• “Change the sky to a sunset in this photo”
• “Add a watermark to the bottom-right corner”

Attach the image to your message or reference one the assistant previously generated.

Credits

Image generation uses credits from your Coral plan, same as text model requests. The cost varies by model and image size.
