GPT Image 2 image generation and editing capabilities

Use the documented image workflows for new visuals, reference-led edits, and production-ready creative variants.

Text-to-image creation

Generate new product, editorial, and campaign visuals from a structured natural-language prompt.

Reference-based editing

Supply an image input to revise an existing visual while preserving important subject and composition details.

Flexible image composition

Create square, portrait, or landscape assets with flexible image sizes for different placements and channels.

High-fidelity visual input

Combine text and image context in one workflow for richer visual direction; audio and video inputs are not supported by this model.

From first test to production

Use the same request contract in the Playground and API, then handle validation, balance, task state, and output retrieval explicitly.

Request lifecycle

  1. 1

    Validate the model, prompt, references, and output settings.

  2. 2

    POST the image request with the documented fields.

  3. 3

    Read the generated output or asynchronous task result returned by the route.

  4. 4

    Store the generated file and request metadata in your own workflow.

Production checks

Parameter validation

Reject unsupported sizes, durations, ratios, formats, or reference counts before submitting.

Authentication and balance

Handle invalid keys, insufficient balance, rate limits, and account-group pricing separately.

Input or policy rejection

Surface the rejected prompt or asset clearly so the user can replace only the failing input.

Task failure or timeout

Keep the task ID, use bounded retries, and never treat a timeout as a successful generation.

Prompt library

GPT Image 2 prompt examples for product and marketing visuals

Start with a concrete subject, composition, output size, and brand constraint; adjust the request fields separately.

Game UI interaction and equipment switching
Game UI interaction and equipment switching

Generated with Image 2

Scene: A 16:9 sci-fi game loadout screen in a blue-purple spaceship hangar. A female armored character stands centered with a glowing violet rifle; armor slots line the left, three weapon slots line the right, and the lower slot is highlighted. Keep the HUD hierarchy, pose, lighting, and equipment geometry fixed for an exact equipment-switch frame. No readable words, logos, invented stats, or watermark. Composition and rendering: Deliver one 16:9 game-interface keyframe. Separate the character, held equipment and HUD into clear depth layers; keep slot spacing and icon scale consistent, with the selected item visually dominant. Preserve the scene-specific game art style. Let material edges catch the existing light without letting interface glow obscure the silhouette. Keep all equipment fully inside the frame. Avoid: warped perspective, malformed anatomy, merged objects, inconsistent shadows, excessive sharpening and watermarks. Follow the scene-specific text and branding restrictions above.

Generated with Image 2

Scene: A rainy night soccer broadcast frame under bright stadium floodlights. A black-uniform player strikes the ball while two white-uniform defenders close in, with the goal and a blurred crowd behind. Keep the broadcast camera angle, blank blue score bars, spray, and motion blur consistent; leave overlays abstract and text-free. No real teams, athletes, logos, or watermark. Composition and rendering: Deliver one 16:9 broadcast still at the decisive instant. Use coherent perspective for the playing surface and equipment, readable separation between competitors, and a softer crowd behind the action. Keep the principal subject sharp, with directional blur limited to fast extremities and spray. Preserve the specified broadcast angle and reserve overlay areas clear of the action. Avoid: warped perspective, malformed anatomy, merged objects, inconsistent shadows, excessive sharpening and watermarks. Follow the scene-specific text and branding restrictions above.

Generated with Image 2

Scene: A closed matte-black square smartwatch with a black strap rests on a wet glossy black tabletop. Water droplets catch a cool blue rim light and a soft reflection sits beneath the watch. Use a low three-quarter product camera and preserve the case, strap, highlights, and empty dark background. No readable branding, extra products, hands, or watermark. Composition and rendering: Deliver one 16:9 commercial product still. Keep the complete product silhouette inside generous crop-safe margins. Resolve edges, seams and material transitions precisely; shape highlights to describe volume without clipping bright surfaces or crushing dark details. Align reflections with the object and light source. Retain the stated camera angle and existing negative space; add no decorative props. Avoid: warped perspective, malformed anatomy, merged objects, inconsistent shadows, excessive sharpening and watermarks. Follow the scene-specific text and branding restrictions above.

Generated with Image 2

Scene: On a rain-soaked observatory roof at sunrise, a lone figure in a long dark coat walks toward a large telescope beside an open dome. Wet stone reflects the warm doorway light; cloud-covered mountains sit beyond. Hold the screen direction and end on the telescope and figure in the same wide composition. No readable text, logos, or watermark. Composition and rendering: Deliver one 16:9 storyboard keyframe, not a collage or an action sequence. Separate foreground, character plane and background through the existing light and atmospheric depth. Keep the stated pose and eyelines readable, and retain environmental landmarks for continuity. Match the described photographic, illustrated or puppet medium; give fabric and surfaces texture appropriate to that medium. Avoid: warped perspective, malformed anatomy, merged objects, inconsistent shadows, excessive sharpening and watermarks. Follow the scene-specific text and branding restrictions above.

Scene: In a bright home kitchen, a surprised cook in a blue shirt and cream apron reaches toward pancakes, a frying pan, flour, bowl, and whisk suspended midair. Freeze the comic cause-and-effect moment with believable weight, warm daylight, and a clear path for each object. No injury, logos, readable words, or watermark. Composition and rendering: Deliver one 16:9 physical-comedy still at the described instant. Make the cause of the gag readable through body balance, grip and object spacing. Separate the reaction from the airborne props; retain believable gravity and contact points. Keep the face and important props sharp, with only restrained directional blur on fast edges. Preserve the stated lighting and room or stage layout. Avoid: warped perspective, malformed anatomy, merged objects, inconsistent shadows, excessive sharpening and watermarks. Follow the scene-specific text and branding restrictions above.

Generated with Image 2

Scene: A rainy period harbor platform shelters people in era-appropriate coats and umbrellas as a vintage green tram arrives on wet tracks. Wooden waterfront buildings and misty mountains sit behind the reflections. Preserve the historical clothing, tram shape, rain direction, and stable wide composition; no readable signage, logos, or watermark. Composition and restoration: Deliver one 16:9 archival-style still. Preserve the original framing, period-specific construction and restrained tonal range; retain monochrome, sepia or faded color as described. Recover modest detail in faces, clothing and architecture without synthetic sharpening. Keep fine grain and authentic aging consistent across the frame; repair damage without replacing historical features. Avoid: warped perspective, malformed anatomy, merged objects, inconsistent shadows, excessive sharpening and watermarks. Follow the scene-specific text and branding restrictions above.

Why use Flatkey for GPT Image 2?

A repeatable GPT Image 2 workflow for product images

Keep image controls and image-input token dimensions together so a prompt test can become a reproducible API request.

All documented controls in one place

Set n, size, quality, output format, background, and moderation before you hand the request to the console.

Image input stays explicit

The catalog exposes token and image-input dimensions; this is not a separate fee for output pixel size, and the final amount depends on request and usage fields.

Marketing-ready starting points

Use product, ad, and storyboard examples as editable starting prompts rather than generic image filler.

No unsupported promises

The page does not promise transparent output, free generation, or a fixed per-image price when those facts are not verified.

API

Use the GPT Image 2 API for generation and edits

Send the model ID with the supported image controls through the documented generation or edits route.
