Grok Imagine guide: write better AI image prompts

A useful AI image prompt starts with a subject, an action or setting, and a clear visual direction. In Grok Imagine, you can start from text or use a reference photo, then review the model and credit estimate before creating an image.

Start with a picture you can describe

“Make something beautiful” leaves most decisions to the model. A more specific prompt gives you a result that is easier to judge. Try this structure:

Subject + setting + composition + lighting + details to preserve.

For example: “A ceramic coffee cup on a pale wooden table, close-up product photograph, soft morning light from the left, neutral background, keep the cup shape simple and leave room on the right for a headline.”

The prompt describes a concrete goal without requiring the model to interpret a long list of conflicting styles. When a first result is close, change one important detail at a time, such as the camera angle or background color.

Choose text generation or a reference edit

Open the AI Image Generator. Text to Image creates a new image from your prompt. Image to Image starts with uploaded reference media and a description of the change you want.

Use a reference when an existing composition, product or portrait matters to the task. Describe both the requested change and what should remain recognizable. AI editing can still change nearby details, so compare important features with the source before publishing.

Review settings and credits before generating

Select a model, a supported aspect ratio and a priced resolution. Image quantity affects the total estimate: two images cost twice the per-image rate for the selected settings.

For example, the configured GPT Image 2.5 rate at 1K is 6 credits per image, so two images have an estimated total of 12 credits. Model prices can change; check the estimate shown for your current selection rather than relying on an old example.

Use a square format for a square placement or a portrait format for a vertical layout. Avoid requesting a larger output simply because it is available; start with the size needed for the project and review whether the generated detail is useful.

Use a focused editing tool for the next change

The Object Remover starts an edit around an unwanted item. Name the target and its position clearly. The Background Remover helps prepare a different background treatment. Transparency depends on the model and output format, so inspect the downloaded file. The Image Upscaler prepares an enhancement workflow, but generated detail should be checked against the source.

Check the result at its intended size

Look at hands, eyes, lettering, product labels and repeating textures. A convincing thumbnail can hide a problem that becomes obvious in a full-size layout. Keep the original, compare versions and download important results to your own storage.
