Run one real GPT Image 2.5 test instead of only reading a launch article
Tutorial-intent visitors need the next action. This page connects prompts, references, image output, pricing, and downloads directly to the generator workspace.
Start with real jobs: product photos, portraits, posters, and ad assets are closer to search intent than a pure feature summary.
For each test case, compare the prompt, reference image, output quality, editability, download quality, and credit cost.
If the first image is close, continue with prompt tweaks, reference control, or upscaling.
Send tutorial visitors into the generator, prompt library, pricing page, and gallery so content traffic does not stop at reading.

始める前の確認
What should a GPT Image 2.5 tutorial start with?
Start with the case closest to your job, such as product photos, portraits, posters, or ads, then copy a similar prompt into the online generator.
Why include pricing in a GPT Image 2.5 test?
A single image only proves output quality. Repeat production also depends on credit usage, upscaling, reference edits, and batch output cost.
When should I use a reference image?
Use references when product shape, identity, packaging, brand color, or layout must stay stable across outputs.
