GPT Image 2.5 Flare & Sunburst in Inliner

Inliner supports both specialized variants of OpenAI's GPT Image 2.5 family: GPT Image 2.5 Flare for fast, layout-faithful new image generation, and GPT Image 2.5 Sunburst for surgical local edits and native rectangular context masks. Both models use standard generation credits (4 image credits per completed render) and are available across Studio, the Embeddable Editor, URLs, CLI, API, and MCP.

IMAGE_GEN_GPT_IMAGE_2_5_FLARE · openai/gpt-image-2.5/flare

Inliner's default OpenAI GPT Image 2.5 path for new images. Tuned for speed and strict prompt adherence when you need crisp in-image typography, packaging mockups, UI concepts, posters, or structured infographics.

Auto-selected when prompts ask for readable text, dense layouts, packaging, or UI compositions.
Resolutions: 1024x1024, 1536x1024, 1024x1536, and up to 2048x2048.
Quality controls: low, medium (default), high, xhigh, and max.

Precision Edit · Sunburst

GPT Image 2.5 Sunburst

IMAGE_GEN_GPT_IMAGE_2_5_SUNBURST · openai/gpt-image-2.5/sunburst

Inliner's precision-edit model for "change this, leave the rest" workflows and the GPT 2.5 (Quality) tier inside the Inliner image editor.

Auto-selected when an edit instruction requires preserving surrounding layout, product geometry, or typography while modifying a target detail.
Native Context Masks: Supports rectangular masked edits with surrounding padded context (useContextMask=1) in the Studio and Embeddable Editor.
Non-destructive patch merge: Only the selected patch is merged back onto the canvas, with one-click Undo.

When to Choose Flare vs. Sunburst

Workflow	Recommended Model	Feature Code	Why It Wins
New packaging, posters, UI heroes, infographics	GPT Image 2.5 Flare	`IMAGE_GEN_GPT_IMAGE_2_5_FLARE`	Fast generation with sharp front-of-pack typography and layout hierarchy up to `2048x2048`.
Surgical local edits ("change the label text, keep the bottle")	GPT Image 2.5 Sunburst	`IMAGE_GEN_GPT_IMAGE_2_5_SUNBURST`	Preserves the untouched scene and lighting while applying exact changes to the target element.
Editor region selection with surrounding context	GPT Image 2.5 Sunburst	`editModel=quality` + `useContextMask=1`	Sends a rectangular native mask over a padded crop so the model sees surrounding context before patching.
Legacy GPT Image 2 workflows	GPT Image 2	`IMAGE_GEN_GPT_IMAGE_2`	Still available in the picker and API for deterministic backward compatibility (GPT Image 2 guide).

Native Masked Selection Edits in the Editor

Inside both Inliner Studio and the Embeddable Editor, switching the AI edit model to GPT 2.5 selects IMAGE_GEN_GPT_IMAGE_2_5_SUNBURST:

Open any image in the editor and draw a selection box around the area you want to change.
Select GPT 2.5 from the edit model picker and check Use surrounding context.
Inliner builds a native rectangular mask over a padded crop so Sunburst sees the surrounding lighting, perspective, and edges.
Only the selected patch is composited back onto your layer stack—and Save & Publish exports a lossless WebP, PNG, or JPG CDN URL.
