How to Use GPT Image 2.5 on iWeaver

Using GPT Image 2.5 on iWeaver only takes a few steps.

Step 1: Open iWeaver

Sign in to iWeaver. Free users receive 3 free conversations every day.

Step 2: Select GPT Image 2.5

Open the model selector and choose GPT Image 2.5.

Step 3: Write Your Prompt

Avoid prompts that are too vague.

Instead of:

Create an AI SaaS cover.

Try:

Create a premium 16:9 AI SaaS blog cover with a clean futuristic workspace, floating documents, blue and violet accents, minimal flat design, and enough empty space for a headline. No logo or watermark.

You don't need a very long prompt. You just need enough detail to guide the model.

Step 4: Generate and Refine

Generate your image and check the composition, style, colors, and unwanted elements.

If most of the image already works, refine it instead of starting over.

For example:

Keep the current style. Simplify the background, make the main object larger, and add more empty space above it.

Step 5: Make the Most of 3 Free Conversations

A useful workflow is:

Generate → Correct → Polish

Use your first conversation to create the image, the second to fix major issues, and the third for final adjustments.

This is usually more effective than generating three completely different versions.

A Simple GPT Image 2.5 Prompt Formula

A practical prompt structure is:

Subject + Composition + Style + Colors/Lighting + Format + Constraints

For example:

White wireless speaker on a gray pedestal, centered composition, premium product photography, soft studio lighting, neutral colors, 4:5 portrait, no text or branding.

That's often enough.

You don't need to describe every tiny detail unless the result requires precise control.

4 GPT Image 2.5 Prompts You Can Copy

SaaS Blog Cover

Create a modern 16:9 AI SaaS blog cover with a clean digital workspace, floating documents, blue and violet accents, minimal flat design, and negative space for a headline. No logo or watermark.

Product Photo

Create a realistic product photo of a matte white wireless speaker on a light gray pedestal, soft studio lighting, minimal background, centered composition, 4:5 portrait, no text.

Social Media Graphic

Create a square AI productivity graphic with notes, charts, and a futuristic workspace, bold editorial style, strong contrast, clean composition, 1:1 format.

YouTube Thumbnail

Create a 16:9 YouTube thumbnail showing a simple sketch transforming into a polished AI-generated image, dramatic contrast, clear focal point, minimal background, and space for a headline.

How to Edit Images With GPT Image 2.5

For image editing, clearly explain both what should change and what should stay unchanged.

For example:

Keep the person's face, pose, and clothing unchanged. Replace the background with a modern coffee shop and match the original lighting and depth of field.

This works better than simply saying:

Put this person in a coffee shop.

For precise edits, changing one or two things at a time usually gives you more control.

Common GPT Image 2.5 Prompt Mistakes

Avoid prompts that are too vague, overloaded with words like “beautiful” or “8K,” or missing basic composition instructions.

Instead of:

Make a beautiful AI image.

write:

Create a 16:9 editorial illustration of a person working with an AI assistant, clean flat design, white background, blue accents, and a centered composition.

Also tell the model where important elements should appear if you're creating a banner, blog cover, or ad.

For example:

Place the main object on the right and leave the left side clear for headline text.

A Reusable Prompt Template

Use this simple template:

Create a [image type] featuring [subject].

Composition: [placement/framing].

Style: [visual style].

Colors or lighting: [details].

Format: [aspect ratio].

Avoid: [unwanted elements].

For most images, filling in these six fields is enough.

How to Add Text to GPT Image 2.5 Images

If you want text inside the image, provide the exact wording.

For example:

Create a minimalist 16:9 AI SaaS blog cover. Add the exact headline "How to Use GPT Image 2.5" in the center using large bold sans-serif text. Do not add any other text or logo.

Be specific about the wording, placement, and whether additional text should be avoided.

Short Prompts vs Long Prompts

Short prompts are useful when you want the model to be more creative.

For example:

Cozy Japanese reading room on a rainy evening, warm cinematic photography.

Longer prompts are better when you already know exactly what you want.

For production images, focus on useful constraints rather than simply making the prompt longer.

Final Tips

Before generating, make sure your prompt answers four questions:

  1. What is the main subject?
  2. What style do you want?
  3. How should the image be composed?
  4. What should the model avoid?

If those are clear, your first result will usually be much closer to what you want.
