What is GPT Image 2.5 on ShimmerPic?

According to ShimmerPic, GPT Image 2.5 is the image generation and editing model OpenAI released on September 8, 2026. In the API it ships as two models, Flare and Sunburst, and ShimmerPic runs both directly in your browser — write a prompt, pick a size and quality, optionally add reference photos, and generate.

Do I need my own OpenAI API key?

No. ShimmerPic is an independent tool that runs the model for you — you sign in with Google and spend credits. The site states it is not affiliated with OpenAI and you do not need your own OpenAI API key.

What is the difference between Flare and Sunburst?

Flare is the fast default with roughly 50% lower latency than GPT Image 2, while Sunburst is the precision model built for polished product and campaign work with longer generation times. On ShimmerPic both cost the same credits, so the trade-off is speed versus detail rather than price.

Can I use it for free, and how much does it cost?

Free access covers base resolution, Standard quality and one reference image. Any purchase unlocks higher resolutions, High quality where supported and up to three references. After that you buy credits outright from $2.99 (a 60-credit pack), or subscribe monthly or annually — there is no unlimited tier.

Do my images stay private?

Results go to your private creations and are not added to the public library; the community gallery only shows prompts and images their authors published elsewhere. You decide what to download or share.
