A transparent PNG laid over the first image in an edit request to guide the edit. It can be passed as a file ID, an HTTPS URL, or a base64 data URL, or uploaded as a file.

How is markup different from a mask?

A mask's fully transparent areas mark where the image should be edited. Markup is an overlay that guides the edit. A request can use one or the other, not both.

Can it read arrows, circles, or handwritten notes?

OpenAI has not said. The spec defines the file format and size rules only. We will show tested examples once 2.6 can be called.

Is markup only for GPT Image 2.6?

No. OpenAI's spec says it supports GPT Image 2.5 and 2.6.

How much will GPT Image 2.6 cost?

Not published. GPT Image 2.5 uses GPT Image 2 token rates; nothing has been announced for 2.6.

What can I open on Topview today?

Markup02
Mark the image. Guide the edit.

OpenAI API spec, image edits, 28 Oct 2026.
Aligned03
Your notes sit exactly on the pixels
The markup layer must match the first image's dimensions after orientation and contain transparent pixels, so marks land where you put them. OpenAI has not said how the model reads each mark.
OpenAI API spec. How the model reads each mark is not documented.
Either/or04
Guide it, or mask it
A mask marks the area to replace. Markup is an overlay that guides the edit. One request uses one or the other, never both, so each edit has a single source of direction.
OpenAI API spec: cannot be combined with mask.

Say what should change and what must stay. Then send the approved still to Image to Video. GPT Image 2.6 is not connected yet; GPT Image 2.5 is available now.
