什麼是 GPT Image?
GPT Image 2.5 is OpenAI's current image generation family and the strongest option on FlyAIgh for any image where readable text is part of the deliverable — posters, ad creatives, product labels, slide graphics, infographics. Where most image models render text as noisy lookalike glyphs, it produces clean letterforms that match what you typed.
It ships in two lines that cost exactly the same. **Sunburst** is the finest line: the one to pick when the lettering has to be exact, the layout is complex, or you are rendering at the Max quality tier. **Flare** is the fast everyday line for quick, stable edits. They differ in model behaviour, not in billing — there is no premium to pay for choosing Sunburst.
Both lines take five quality tiers (Low, Medium, High, Extra high, Max), render at 1K, 2K or 4K, and support 15 aspect ratios from 1:1 through 21:9 and 1:3. Both do text-to-image and image editing, accepting up to 16 reference images in edit mode, and both can output a transparent background.
Pricing is token-based, so the credit cost moves with what you ask for rather than sitting at a flat rate. At Low or Medium quality a 1K image is 1 credit; High 2K is 7; Max 4K at 1:1 is 40. Each reference image adds roughly half a credit. **One effect worth knowing: aspect ratio changes the price**, because a square image spends the full pixel budget and a wide one does not — at Max 4K, 1:1 costs 40 credits while 21:9 costs 14. Symmetric ratios cost the same (16:9 and 9:16 are identical). The exact total is always shown before you generate.
GPT Image 2, the previous generation, remains available on the same page at 2 credits per image with 4 reference images and five aspect ratios. Pick it when the job is simple and cost per image matters more than resolution or layout control.
The family is particularly strong at faces, hands, on-image text, structured layouts and any prompt with explicit lettering ('a poster that reads ...'). It is weaker than Midjourney v7 for distinctive artistic style. On FlyAIgh it ships under the same credit wallet as every other model — no separate OpenAI subscription or API key.
