GPT Image 2.5 Flare vs Sunburst for Scientific Figures

Compare GPT Image 2.5 Flare and Sunburst for scientific figures: 24 outputs reveal differences in labels, layout, focused edits and generation time.

Try Flare for quick layouts; Sunburst corrected the target label in both outputs of our editing example.

Which version helps you finish the scientific figure with fewer revisions? We used six shared tasks, two outputs per version and the same reference for the editing task. The 24 outputs let us compare required content, visible layout and recorded generation time. Both versions are available in SciFig Illustration.

GPT Image 2.5 Flare vs Sunburst: Which Should You Choose for Scientific Figures?

Choose Flare to explore a composition; try Sunburst first for an edit similar to our one-label correction.

Scientific taskStarting choiceObservation in these outputs
Four-panel study workflowFlare for quick layout explorationBoth preserve four panels, five labels and three connectors
Labeled cell illustrationChoose by the visual styleBoth include eight labels; Flare uses flatter fills, Sunburst more shading
Scientific symbolsEither version with exact stringsBoth retain all six strings in both runs
Simple mechanismEither version with explicit arrowsBoth show three nodes, two arrows and two relationship labels
Graphical abstractFlare for framed stages; Sunburst for stages without framesBoth retain three stages and two connecting arrows
Targeted label correctionSunburst for a similar editBoth Sunburst outputs repair the wording; both Flare outputs retain a misspelling
OpenAI positions Flare for fast, high-quality generation and Sunburst for demanding visual detail and editing precision. The task observations above help turn those broad roles into a practical starting choice. For a comparison with Google's model, read Nano Banana 2.1 vs GPT Image 2.5 for Scientific Figures.

SciFig: Continue With the Same Research Content

Start in SciFig Illustration with text, a sketch or a reference image to create a scientific figure. Edit text or icons directly when needed, or vectorize the image to SVG for element-level editing in Canvas. When comparing Flare with Sunburst, keep the content brief unchanged so the version choice is the main difference.

Scientific Figure Layout: Framed or Open Stages?

The graphical abstracts preserve the same workflow but differ in how strongly they separate the three stages.

The prompt requests Synthesis → Characterization → Image analysis, with a beaker and particles, a microscope and an analysis image. In these outputs, Flare puts the stages inside frames; Sunburst uses a layout without frames. Both retain the three labels and two arrows.

Use framed stages when each operation needs a distinct panel. Use an open layout when the workflow should read as one continuous explanation. At your intended figure size, inspect the smallest objects and whether the arrows establish the sequence without competing with the artwork.

Scientific Figure Labels, Symbols and Mechanism Arrows

Both versions supplied the requested cell labels, notation strings and simple mechanism connections in both runs.

TaskExact requirementWhat to check beyond presence
Animal cellEight named structures and labelsEach leader line ends on its intended structure
Scientific notationα, β, ΔG, μm, CO₂, s⁻¹Greek glyphs, subscript and superscript at display size
RAF → MEK → ERKThree boxes, two arrows, two Phosphorylation labelsDirection and meaning of each connection

The cell outputs differ in appearance: Flare uses flatter fills, while Sunburst shows more shading and membrane detail. Choose the style that fits the surrounding scientific figure. For a scientific figure with many labels, allow space outside the objects and avoid crossing leader lines.

The scientific figure examples and prompt structure show these tasks. Copy the actual terms and characters into the brief; “add scientific labels” leaves both content and placement unresolved.

Scientific Image Editing: Correct One Label, Preserve the Layout

Both Sunburst outputs read Treatment group; both Flare outputs retain a misspelling in this correction task.

We supplied the same two-panel scientific workflow image and asked for one change: replace Treatmet group with Treatment group at the top right of panel A. The instruction also names the other labels, objects, arrows, panel positions and colors to preserve.

Both attempts from each version are shown directly. Read the target wording first, then compare the tubes, arrows and panel boundaries with the input. Sunburst is the useful starting choice for an edit like this; that observation applies to this correction task.

For your own scientific image edit, state the old wording, exact replacement and location. Then describe what should remain. Select an output to open the full prompt, copy it or generate in SciFig; upload the supplied reference when trying the editing task.

Tip

Make one focused change per instruction. After correcting a label, review the result before changing the panel layout or palette.

Scientific Figure Generation Time and the Next Editing Step

Flare's recorded median was 36 seconds and Sunburst's was 40 seconds; combine time with the revision needed.

Recorded generation timeFlare: 12 outputsSunburst: 12 outputs
Median36 seconds40 seconds
Range15–53 seconds35–80 seconds
Shared settings2K request, landscape 16:92K request, landscape 16:9

The ranges overlap. A faster first output helps when exploring scientific figure layouts; a correct targeted edit can save an additional revision. Inspect required objects, labels and relationships, then choose the output that is easier to finish.

In SciFig Illustration, edit text or icons directly when needed. For element-level editing, you can also vectorize the scientific image to SVG and open it in Canvas. An existing SVG can also be imported directly. The earlier discipline comparison provides more examples of inspecting scientific content and structure.
