How does image generation work in Ceres?
Image generation runs during the conversation. If you have an image project open, generated images can also be saved there. You can create a whole set of images and keep working without manually saving every file.
Image generation currently works through the OpenRouter provider. Choose the image model you prefer from the supported list, including models such as Nano Banana, Flux Dev, or another OpenRouter image model when available.
Can I send images?
Yes. To understand images, select a model that supports vision.
Can I edit images with AI?
Yes, when the selected provider and model support image editing or image generation workflows. You can ask the AI model to transform an image, follow instructions, and create a new image based on one, two, or three previous images.
For direct cropping, resizing, conversion, and local background removal, Ceres is the better tool. For generative image changes, use Ceres with a provider and model that supports the image task you want.
Why does overlay not work when I drop an image into the Ceres sidebar?
If dropped images are not staying as overlays, open Ceres settings from the gear icon and enable overlay images.
When overlay images are disabled, the default action is to clear the temporary image after you crop or drop a new image into the sidebar.
Why is Ceres background removal slow or crashing?
Ceres background removal uses local AI. On older computers it may fall back to CPU processing, which can be very slow. On some older systems, the processor or browser may not support the required features, which can lead to messages such as worker crash, SIMD not supported, or similar errors.
Try updating your browser, graphics drivers, and processor drivers. If possible, test on a newer machine or a computer with better GPU support. At the moment, we do not provide cloud background removal for Ceres unless we build a dedicated cloud service later.
Why is Ceres upscale very slow?
Ceres upscale uses local AI. To increase resolution, the AI must infer likely extra image detail and rebuild a larger version of the image, so the process can be especially slow.
Upscaling starts only after you select the specific area you want to make higher resolution. We use this method so the AI has less image data to process and can finish faster. If needed, you can still select the whole image and upscale everything.
If you do not have a strong graphics card, avoid relying on upscale in a production workflow. Our app does not use a cloud provider for upscale or background removal, so both tasks depend on your local machine.
Drag and drop is not working in Visual Studio Code
When dragging an editor tab into Image Editor, hold Shift. VS Code can otherwise block the normal drop behavior. The same applies when dropping a tab into Ceres IDE Chat.
