gimp-pyrogen is a plugin for GIMP, a free image editing program, that adds AI image generation directly into the editor's menus. Once installed, you can generate a brand new image from a text description or edit part of an existing image, and the result appears as a new layer inside your GIMP project instead of a separate file you have to import. It supports two AI providers: Google's Gemini image model, nicknamed Nano Banana, and OpenAI's image model. You choose which part of your image the AI should look at when generating, whether that is your current selection, the active layer, or the whole picture, and the plugin sends that visible content along with your prompt so the AI can use it as context. The finished result is automatically resized to fit back into the area you selected, either preserving its proportions or stretched to fill the space exactly. You can also attach separate reference images for extra context, and the generation happens in the background with a progress indicator so GIMP does not freeze while you wait. A notable design choice is that the plugin avoids any external Python packages entirely, calling each AI provider's web service directly using only tools built into Python itself. This matters because the Flatpak version of GIMP, a common way people install it on Linux, uses a locked down Python that cannot install extra packages, so this approach lets the plugin work there without any special setup. To use it, you need GIMP version 3.0 or newer, and a paid API key from Google, OpenAI, or both, saved into a small file in your home folder. Installation is done by cloning the code and running an included script that links the plugin into GIMP's plugin folder, then restarting GIMP. This tool is aimed at people who already use GIMP for image editing and want to bring AI generation into their existing workflow, and it is released under the MIT license.
