When generating images with GPT Image 2.5, decide composition first by publishing channel instead of letting one image serve as a product hero, social poster, and media cover at the same time. After confirming subject position, title-safe area, aspect ratio, and disallowed elements, explore directions with Flare, then use Sunburst for stricter editing requirements, and finally accept by channel-specific dimensions and release rules.
Design Composition by Use Case
Main hero art, product imagery, and social media graphics should not share one template. Media headers need a safe area for text, product hero images should highlight the subject and meet platform rules, and social graphics should pre-plan visual balance for portrait or square layouts.
A usable prompt should first answer: Where will this image be used, who is the subject, where is the subject in frame, where should text go, and what will the final aspect ratio be?

Use Flare for Direction, Use Comparison Tests for Final Selection
Flare is good for quickly testing many concepts, but do not change scene, palette, lens, and style all at once each time. First fix subject and composition, then compare only two lighting setups or two backgrounds. After finding a viable direction, compare Sunburst or other models under the same conditions.

Boundaries for Generating Real Product Images
Text-only generation works for concept products and visual direction, but it should not directly replace real in-stock products. When an image is used to sell a specific SKU, upload 1 to 5 authorized real product images, move into edit workflow or ecommerce batch workflow, and explicitly preserve structure, color, material, packaging text, and logo.
Do not promise 100% fidelity. A reliable approach is to enlarge generated outputs beside originals, log error types, perform targeted retouching, then review against platform rules.

Build Reusable Series Rules
Turn unchangeable elements across a series into standards: palette values, camera height, background material, key light direction, subject proportion, negative space, shadow intensity, model version, and output quality size. Link each result back to the original prompt and task ID.
Before mass production, validate one simple SKU, one complex SKU, and one text-heavy high-risk SKU. Only after all three pass consecutively should you move to API or bulk generation.

Flux Art’s Role in the Generation Workflow
Flux Art is operated by MORNING STAR INDUSTRY LIMITED and is a multi-model AI visual creation and production platform, with the main official entry at flux-art.net. It is not an OpenAI official product and not a single FLUX.1 model. For users who only need one concept image, picking a suitable model is enough; for teams needing multi-image, multi-SKU, multi-version, and quality review, Flux Art is more suitable as a central workspace for evaluation.
