How to use GPT-4o

Use GPT-4o here for text-to-image and reference-based image editing

Begin with a detailed prompt, add up to five reference images if your project needs them, and refine your final result with follow-up instructions all on this single page.

Write the image brief like a layout request

Clearly outline your core subject, desired composition, material textures, lighting style, and any exact text that must be included in the final image.

Upload references when the model should follow them

Add up to five images when you want GPT-4o to match an existing product, brand palette, specific environment, or your desired creative visual direction.

Refine with follow-up instructions

Narrow down your prompt, request layout adjustments, or clarify which elements need to stay fixed until your final image meets your requirements.

Core strengths of GPT-4o

What stands out about GPT-4o as a hosted image model

GPT-4o differentiates itself from other hosted image models when your project requires adherence to long detailed briefs, clean readable on-image text, or integration of multiple reference inputs in a single streamlined workflow.

Readable text and layout control

OpenAI prioritizes text rendering as a core differentiator, making GPT-4o far more reliable for text-inclusive designs like posters, menus, product labels, and annotated assets compared to most general-purpose image-only models.

This capability is critical when both your main headline and supporting text need to remain intact and readable after generation.

It is especially useful for posters, menus, packaging labels, diagrams, and ad creatives with short copy blocks.

You can explicitly define layout hierarchy directly in your prompt instead of leaving element placement up to random chance.

Detailed instruction following in one hosted tool

GPT-4o is ideal when you need consistent composition, targeted styling, clear callouts, and exact copy all handled within a single prompt request, so you don’t have to split your workflow across multiple disconnected tools.

It processes creative-brief style prompts far more reliably than image tools that are only optimized for short, keyword-focused prompts.

This makes it perfect for drafting ad creatives, building educational explainers, and putting together product concept boards.

You can refine your idea iteratively without ever leaving the hosted generation session, streamlining your creative workflow.

Multiple reference images in one request

OpenAI natively supports image generation and editing with multiple image inputs, and this page allows up to five separate reference images per GPT-4o request.

This flexibility is extremely helpful when different references define your product, brand palette, desired styling, or spatial layout direction.

It works far better than single-single-reference workflows when multiple input references all need to influence the final output.

Your final output will stay much closer to your original design brief when each reference contributes a clear, specific part of the creative direction.

Useful for diagrams, explainers, and labeled visuals

GPT-4o isn’t limited to photorealistic marketing ads. It also excels at creating clear diagrams, numbered process flows, and information graphics where structural clarity matters just as much as visual style.

This expands its utility far beyond standard product beauty shots or cinematic concept art pieces.

It is one of the strongest hosted options when your image needs to explain a process or compare multiple items clearly for an audience.

This makes it ideal for user onboarding content, educational materials, packaging guides, and internal product communication.

Best use cases

Where GPT-4o is most useful

GPT-4o delivers the most value for text-aware creative layouts, annotated assets, reference-aligned edits, and visuals that require a detailed prompt to stay organized and on-brief.

Poster and campaign layouts with real copy

Use GPT-4o to create event launch posters, restaurant menus, retail signage, and announcement creatives where the on-image text is a core functional part of the final design.

Product concept boards and branded ad drafts

Quickly build product concept boards, labeled product mockups, and marketing visuals that balance clean visual structure, detailed product rendering, and short explanatory text labels.

Reference-based edits with multiple inputs

Input multiple reference images when you need product identity, brand palette, or existing design direction to carry through consistently to your final output or edit.

Instructional graphics and explainers

Generate clear numbered diagrams, short educational explainers, and annotated visuals where the image needs to communicate information, not just serve an aesthetic purpose.

When to choose GPT-4o

Choose GPT-4o when readable text and multi-reference editing matter more than open weights

GPT-4o is the right choice for your project when you need readable on-image text, multiple reference inputs, or multiple rounds of iterative editing within a streamlined hosted product. It prioritizes structured creative work with reliable prompt adherence over local self-deployment capabilities.

Choose GPT-4o when the brief is detailed and the layout has to survive

Pick GPT-4o when you’re working from a detailed creative brief and need your layout structure to stay intact. It is the best option when your prompt requires clear structure: exact text, intentional annotations, multiple reference inputs, and a defined visual hierarchy. It shines when your image needs to communicate specific information, not just serve an aesthetic purpose.

Use another model when you care more about open weights or a different default style

Opt for a different model when open weights or local deployment are higher priorities than hosted workflow convenience, or when you prefer a different default visual style. Choose Z-Image when open weights and local deployment are part of the decision. Choose Seedream 4 or Flux 2 when you want a different built-in visual style and do not specifically need GPT-4o's text and multi-reference strengths.
