Nano Banana API: Edit Images with Gemini in Code
Article image or reusable cover for OpenRouter
OpenRouter has enabled image editing with text instructions through its API.
You send a source image and a text description of desired changes in a single request and receive the edited image back. The guide demonstrates how to do this in Python and TypeScript, and explains that you can easily switch to a different editing model by changing a field in the code. You can also make multiple edits in sequence by sending each result back as a new source image.
You send the source image and an edit prompt to google/gemini-3.1-flash-image through the OpenRouter API, and the edited image comes back in the response.
