ShimmerPic

What is ShimmerPic?

ShimmerPic is an independent, browser-based creative tool that runs the GPT Image 2.5 image generation and editing models released by OpenAI on September 8, 2026. In the API these appear as two models — Flare, described as the fast default, and Sunburst, described as the precision model — and ShimmerPic makes both available in the browser without requiring an OpenAI API key.

ShimmerPic states it is not affiliated with OpenAI. A prompt library is curated from the open awesome-gpt-image-2 collection, and each prompt card credits its author and links to the original post.

How to use ShimmerPic?

1. Sign in (the page mentions signing in with Google) and start with 6 free credits for a new account.
2. Write your own prompt, or open one of 531 community prompts from the library, which fills the text in for you.
3. Optionally add up to three reference photos, each up to 10 MB and 4,096 px on the long side.
4. Choose a model (Flare or Sunburst), an aspect ratio, a resolution tier, and Standard or High quality. The page states the price updates as you change settings, before you generate.
5. Generate the image. The page suggests trying Flare while exploring and switching to Sunburst for a version to keep.
6. Refine by opening any result as a reference and describing the change. Results are saved to your creations and can be downloaded or reused as references.

Core features of ShimmerPic

GPT Image 2.5 Flare and Sunburst in the browser

ShimmerPic runs both GPT Image 2.5 models without an API key. Flare is presented as the fast default; Sunburst is presented as the precision model for polished product and campaign work. Credits cost the same for both models.

Prompt library

The library contains 531 community prompts, sorted by output type such as product shots, posters, characters and brand boards, and each card is shown with the image its author shared. Opening a prompt fills in the text.

Reference photos

Up to three reference photos per image can be added, each up to 10 MB and 4,096 px on the long side. Each reference photo adds 3 credits.

Sizes, settings and limits

Six aspect ratios are available: 1:1, 4:5, 3:2, 2:3, 16:9 and 9:16. Resolution tiers are 1K, 2K and 4K, in Standard or High quality. The page states the prompt is submitted in full without silently cutting it.

Editing across turns

Any result can be opened as a reference and edited by describing the change. The page says the model follows editing instructions across multiple turns and keeps what was not mentioned.

Private creations

Results are saved privately in your creations at full resolution and are not added to the public library. The community gallery only shows prompts and images their authors published elsewhere.

Reported credit costs

Base price per image is identical for Flare and Sunburst. On the published table, 1K costs 3 credits Standard or 12 High; 2K costs 6 Standard or 24 High; 4K costs 12 Standard or 40 High. Prompts over 500 bytes add 2 credits per further 1,000 bytes, and each reference photo adds 3 credits. The Studio shows the exact quote before generating. Failed generations are refunded, and the page states there is no unlimited tier.

Use cases of ShimmerPic

Product photography

Upload one photo of a product and describe the surface, light and camera; the page says the product stays recognisable while the studio is rebuilt around it, for packshots, lifestyle scenes and hero crops.

UGC-style visuals

Generate the product in a hand, on a desk or in a car cupholder, shot like a phone photo rather than a studio image, to produce variations for ad testing.

Posters and flyers

Quote the headline and small print and describe where each sits, so the model renders the words in the described layout, for event one-sheets, sale flyers and typographic prints at print resolution.

Mockups

Use a logo or label as a reference and place it on a T-shirt, box, tote or wall in a requested angle and light, without a template library.

Frequently asked questions about ShimmerPic

What is GPT Image 2.5?

The page describes it as the image generation and editing model OpenAI released on September 8, 2026, coming as two models, Flare and Sunburst, in the API. ShimmerPic runs both in the browser.

Can I use it for free?

Every new ShimmerPic account gets 6 free credits, described as enough for two 1K images with a short prompt on either model. After that, credits are bought in one-time packs from $9 or via monthly and annual plans. There is no unlimited plan and no per-model surcharge.

What is the difference between Flare and Sunburst?

Flare is the fast default, described as having 50% lower latency than GPT Image 2. Sunburst is the precision model with longer generation times, built for polished product and campaign work. They cost the same credits on ShimmerPic.

Do I need my own OpenAI API key?

No. ShimmerPic is an independent tool that runs the model for you; you sign in, use credits, and images stay private in your creations until you download or share them.

Do my images stay private?

Yes. The page states results go to your private creations and are never added to the public library; the community gallery only shows prompts and images their authors published elsewhere.

Can I edit an image after generating it?

Yes. Open any result as a reference and describe the change. The model follows editing instructions across multiple turns and keeps what you did not mention.
