GPT Image 2.5 Sunburst cutaway diagram promptVolcano Cutaway

The exact text-to-image prompt behind this picture, made with GPT Image 2.5 Sunburst.

Prompt

Vertical 4:5 portrait frame. A clean 3D cutaway diagram of a volcano showing the magma chamber, main conduit, side vents, layers of ash and lava and an ash cloud rising, textbook-clean render with soft colors, small neat labels on leader lines: MAGMA CHAMBER, CONDUIT, VENT, ASH CLOUD, cream background.

Style prompt guide

Style traits to keep

A textbook-style geological cross-section reveals the inner workings of an erupting volcano with clean lines and soft lighting. GPT Image 2.5 Sunburst excels at rendering crisp callout typography alongside smooth, semi-matte 3D geometry. The combination of muted educational palettes and structured layout produces a diagram that looks straight out of an earth sciences manual.

The textbook diagram style uses distinct structural and aesthetic traits to communicate complex anatomy with maximum clarity.

Composition
A crisp cross-section bisects the subject, revealing internal layers and plumbing alongside a partial view of the exterior.
Line
Delicate, horizontal leader lines extend outward from internal elements to tether annotations neatly outside the main subject.
Palette
Restrained, educational tones with soft oranges, muted reds, and cool greys rest against a neutral cream background.
Texture
Surfaces are rendered with smooth matte shading, avoiding photorealistic volcanic grit to keep each geological strata legible.

What defines this look

  1. composition and formatVertical 4:5 portrait frame. A clean 3D cutaway diagram of a volcano

    Establishes the aspect ratio and cross-section perspective. Removing cutaway turns the volcano into a solid exterior mountain landscape without exposing internal chambers.

  2. subject anatomyshowing the magma chamber, main conduit, side vents, layers of ash and lava

    Lists the exact scientific layers and pathways needed inside the rock face. Removing these parts leaves the cross-section flat or filled with generic solid rock.

  3. style and finishand an ash cloud rising, textbook-clean render with soft colors,

    Enforces an educational, non-photorealistic aesthetic with restrained saturation. Swapping this for cinematic or dramatic lighting introduces harsh shadows and gritty realism that obscure the diagram.

  4. typographic and backdrop detailssmall neat labels on leader lines: MAGMA CHAMBER, CONDUIT, VENT, ASH CLOUD, cream background.

    Prompts the model to draw thin connector lines paired with legible uppercase text against a clean backdrop. Omitting the labels produces an unannotated cutaway model.

Same style, new subjects

Urban street cutaway

Replaces volcanic geology with municipal infrastructure while retaining the educational diagram style.

Prompt

Vertical 4:5 portrait frame. A clean 3D cutaway diagram of a city street showing the subway tunnel, water mains, sewer pipes, foundational bedrock and road traffic above, textbook-clean render with soft colors, small neat labels on leader lines: SUBWAY, WATER MAIN, SEWER, BEDROCK, cream background.

Espresso machine diagram

Applies the cutaway cross-section and leader-line callouts to consumer mechanics and industrial design.

Prompt

Vertical 4:5 portrait frame. A clean 3D cutaway diagram of a manual espresso machine showing the water reservoir, brass boiler, pressure pump, portafilter basket and internal heating element, textbook-clean render with soft colors, small neat labels on leader lines: RESERVOIR, BOILER, PUMP, PORTAFILTER, cream background.

Feline paw anatomy

Translates the textbook cutaway aesthetic into biological and veterinary illustration.

Prompt

Vertical 4:5 portrait frame. A clean 3D cutaway diagram of a cat paw showing the phalange bones, flexor tendons, retractable claw mechanism, protective sheath and leathery pad, textbook-clean render with soft colors, small neat labels on leader lines: CLAW, TENDON, PHALANGE, PAD, cream background.

Model and settings

Keep the ratio set to 4:5 in portrait orientation, as vertical space is necessary to stack the underground magma chamber, mountain cone, and ash plume comfortably. Leave quality on high so GPT Image 2.5 Sunburst renders sharp lettering on the leader lines instead of blurred glyphs. Text-to-image mode is ideal here because the scene relies on pure structural generation rather than an existing photo.

When the style drifts

The cutaway looks like a real photographed rock face with heavy dirt, losing the clean diagram style.
Replace soft colors with vector infographic illustration or matte 3D textbook model, and remove words like realistic or photo.
Text labels merge together or appear misspelled across the volcano face.
Reduce the label request to just three uppercase terms, for example: labels on leader lines: MAGMA, CONDUIT, ASH.
The leader lines float aimlessly or cross over each other into a tangled web.
Add horizontal straight leader lines and generous margins around the cutaway to give the typography room to breathe.

Questions about this style prompt

Why does the model sometimes misspell diagram labels?

Generating readable text inside 3D spaces requires significant spatial planning. Keep text prompts short, uppercase, and limited to three or four words. Placing them at the end of the prompt helps the model prioritize character accuracy.

Can I swap the cream background for a black chalkboard?

Yes, changing cream background to slate chalkboard background works well. When doing this, specify white chalk leader lines and bright callout text to maintain high contrast and legibility against the dark field.

How do I make the cross-section look more schematic and less 3D?

Replace clean 3D cutaway diagram with flat 2D vector technical cross-section. This instructs the model to flatten depth cues, drop ambient occlusion, and emphasize crisp planar line work typical of engineering blueprints.
