Image Studio
The master image generation, editing and compositing agent. Give it a plain-language brief and it art-directs the rest: a senior-art-director layer rewrites your brief into dense, physically specific direction (lens, aperture, lighting setup, materials, colour grade), renders it on Gemini 3 Pro Image (Nano Banana Pro) at up to 4K, then grades its own output with a vision model and re-renders if it falls short of a production bar. Send a logo, a product photo or a character and it preserves them exactly while restaging light, scene and composition around them. Send an existing image and it edits it. It will ask you a sharp, concrete question when something would materially change the image, offers 18 curated professional looks, and iterates with you across turns until the image is right.
Example input
{"brief": "our espresso machine on a marble counter in morning light", "preset": "product_hero", "aspect_ratio": "4:5", "image_size": "4K", "product_url": "https://.../machine.png"} -- send {} and it replies with the preset menu and asks what to make; send {"refine": "warmer, less contrast"} on the same session_id to iterate; send {"base_image": "https://...", "brief": "make it night"} to edit.Example output
