Straight Answers on GPT Image 2.5 Before You Spend a Credit
You get the honest version here. You learn what a GPT Image 2.5 render costs, what 4K really means on this page, and which plan allowance does not cover it.
What is GPT Image 2.5?
GPT Image 2.5 is the image model OpenAI released on 8 September 2026. On Seadanse it runs as a hosted browser tool. Type a prompt or add up to three reference images, choose 1K, 2K or 4K, and download a JPG. It does not output video.
Is GPT Image 2.5 the same as ChatGPT Images 2.5?
Same release, two names. ChatGPT Images 2.5 is what OpenAI calls it inside ChatGPT, where it lives in a chat thread under that plan's limits. GPT Image 2.5 is the developer name for the same model. You need neither a ChatGPT seat nor a GPT Image 2.5 API key to use this page.
Is GPT Image 2.5 free to use on Seadanse?
Sign-up is free and needs no card. You get 40 one-time starter credits, which covers about 6 renders on GPT Image 2.5 Flare at 6 credits each, or 4 on Sunburst at 10. Top up with a credit pack, or take a Pro plan, which renders both checkpoints without spending credits for the length of its unlimited-images term.
How many credits does a GPT Image 2.5 image cost?
A flat rate that never moves with size: 6 credits on GPT Image 2.5 Flare and 10 on Sunburst, at 1K, 2K and 4K alike. For comparison, GPT Image 2 costs 4, Grok Imagine Image 2 costs 5, Seedream 5 Lite costs 6, and Nano Banana 2 costs 7 to 16 depending on size — so a 4K Nano Banana 2 image is 16 against Flare's 6. A failed render returns its credits automatically.
Is GPT Image 2.5 included in the Pro plan's unlimited images?
Yes, both checkpoints. On Pro, Flare and Sunburst render without spending credits for the length of the unlimited-images term, one at a time and at a slower queue than a paid render. Off Pro, or once that term ends, each render bills its own rate — 6 credits on Flare, 10 on Sunburst.
Does GPT Image 2.5 really render 4K, and which aspect ratio can I pick?
Yes. Choose 1K, 2K or 4K before you render, then one of eight framing options: 1:1, 2:3, 3:2, 3:4, 4:3, 9:16, 16:9, or auto. The image comes back in the framing you picked, at the size class you picked. Finished GPT Image 2.5 images download as JPG. There is no upscaler here — the size is set before the render, not after.
How many reference images can I upload to GPT Image 2.5?
Up to three, and they compose into one new frame rather than running as separate jobs. Other sites quote higher counts taken from OpenAI's raw API; three is what we verified on this surface. References cost no extra credits, and leaving the upload empty gives you text-to-image from the prompt alone.
How is GPT Image 2.5 different from GPT Image 2 on Seadanse?
Both stay on the model pill, so nothing you built on GPT Image 2 goes away. GPT Image 2.5 is the newer release. It adds a real 1K, 2K and 4K size picker, takes up to three composed references instead of one, and bills 6 credits on Flare or 10 on Sunburst against GPT Image 2's 4. Stay on GPT Image 2 when your prompts are already tuned to its look.
What is the difference between GPT Image 2.5 Flare and Sunburst?
They are OpenAI's two GPT Image 2.5 checkpoints, and the model pill offers both. OpenAI positions Flare as the fast everyday default, and Sunburst as the one built for work where editing precision matters most, at longer generation times. On Seadanse the difference you can see is the price: Flare bills 6 credits an image, Sunburst 10. Both take the same prompts, the same eight framing options, up to three reference images, and 1K, 2K or 4K.
