Edit inside a 66-megapixel image.
Ideogram 4.5 Precise Edit changes one region of a very large image at that region's own pixels, then puts it back. Set a window, or let it fit one to your mask, and there is no downscaling to fit the model, no cropping and stitching, no seam where the crop went back.
The rest of the picture comes back byte for byte.
Editing a large image usually costs you one of two things: scale it down so the model will take it and lose the detail, or crop the area, edit the crop and paste it back with a visible border and a colour shift. This model takes the whole image, works only inside the window you point at, and returns the edited image at the original's full size.
Measured by us, not quoted. We compared Ideogram's before and after pixel by pixel and ignored differences below compression noise. Everything outside the outlined region matches the original.

The edit window.
An area of at most 2048 × 2048 pixels, anywhere in the frame, in any shape up to 6:1.
The image it sits in.
Inputs up to 67,108,864 pixels and 50 MB. Ideogram's own example is a 14,495 × 4,568 panorama — 66.2 megapixels.
Everything outside it.
Pixels beyond the window come back exactly as you sent them.
What you get back.
With a window set, the full image, not the crop. Nothing to reassemble afterwards.
Three ways to set the window.
The context_window parameter decides which pixels the model reads at full resolution. A mask inside it narrows the edit further, to the pixels allowed to change. The image itself can be up to 67,108,864 pixels and 50 MB.

One image, many rounds.
Ideogram says 4.5 does not build up artifacts from one edit to the next, so the same image can go through round after round. Below are four of Ideogram's own chains. Pick a step to read its prompt, then drag to compare it with the original.

“Make it dusk: deep blue sky, warm interior light glowing in all the windows and doorways, uplights on the columns. Keep everything in place.”

Product photography · 6 edits
“Show the same breakfast scene from a new camera angle: slightly higher and about 35 degrees to the left, a three-quarter view of the toaster with the strawberries and jam in the foreground. The same toaster, props and light.”
The original is generated from a prompt. Each step edits the one before it.

“Turn this into a modern, high-resolution photograph of exactly this moment, as if it were shot today on a full-frame digital camera with a sharp prime lens: the same people with exactly the same faces, expressions, pose, hair, clothes and framing, every edge where it is now; crisp fine detail in the eyes, eyelashes, hair strands and fabric weave; natural real skin with pores and fine lines, no smoothing; a clean, smooth backdrop with no specks, dust, grain, stains or leftover damage patches; rich, natural colour and a full tonal range.”
The original is a damaged old photograph. Each step edits the one before it.

“Translate the marquee line into French: change "FRESH BAGELS EVERY MORNING" to "BAGELS FRAIS CHAQUE MATIN", in exactly the same black marquee letters, size and position. Keep "MAPLE", the building, the sky and everything else exactly as they are.”
The original is an image of a bakery marquee. Each step edits the one before it.

Big file, small change.

Recolour or restyle a product in a catalogue image at full resolution.
A detail in a huge frame.
Aerial and stitched work, where downscaling throws away the reason the file is that size.
Billed per image generated.
The quality you request sets the price, and on Generate so does whether you send reference images. On Precise Edit, neither the size of the image nor the size of the window changes it. An image that Ideogram's safety filter withholds is still generated, and still billed.
