GPT-Image-2.5 in Adobe Firefly: Flare vs Sunburst for Product Photos and Ads

Adobe added GPT-Image-2.5 Flare and GPT-Image-2.5 Sunburst as partner models in Firefly after OpenAI launched ChatGPT Images 2.5 on September 8, 2026. Adobe’s partner-model list, updated September 9, 2026, puts Flare on text-to-image, Prompt to Edit Image, Style generator, and Firefly Boards. Sunburst sits on text-to-image, Prompt to Edit Image, and Boards. Partner models are not Adobe models. Pick the surface from the job. Review lighting, labels, and rights before you publish.

A new dropdown is not a new brief. One subject, one crop, one honest claim still wins. You can draft in FreeGPTImg, generate with GPT Image 2 or the AI text-to-image generator, keep materials honest in AI product photography, recrop a winner in AI social media ads, or keep a ChatGPT-style loop on the ChatGPT image generator free alternative.

What Adobe listed on September 9, 2026

OpenAI shipped ChatGPT Images 2.5 for ChatGPT, ChatGPT Work, and Codex, plus two API models: GPT-Image-2.5 Flare and GPT-Image-2.5 Sunburst. Adobe is a launch customer. In OpenAI’s announcement, Adobe said the GPT-Image-2.5 models are now in Firefly.

Adobe’s own help page is the inventory to trust, not a recap headline. Partner models are not developed by Adobe. You decide whether a model fits the job. Availability can vary by country or region.

Surface	Where Adobe lists it	Best job	Speed / control	Do not treat it as
GPT-Image-2.5 Flare in Firefly	Text to image, Prompt to Edit Image, Style generator, Firefly Boards	Fast variants, social drafts, transparent cutout tests	Faster iteration; Adobe notes generation/editing quality and native transparency	A Firefly-trained Adobe model, or a listing photo you have not reviewed
GPT-Image-2.5 Sunburst in Firefly	Text to image, Prompt to Edit Image, Firefly Boards	Product stills, faces you must keep, campaign polish	Slower, tighter; Adobe notes facial preservation, aesthetics, transparent-image quality	A high-volume mood board where speed beats control
GPT Image 2 in Firefly or elsewhere	Already a separate partner / API model	Existing briefs you do not want to relabel	Known GPT Image 2 loop	“Generated with Images 2.5”
ChatGPT Images 2.5	ChatGPT, Work, Codex	Conversational edits, Sketch, Poster/Merch templates	One Images 2.5 experience, not a Flare/Sunburst toggle	Firefly Boards, Style generator, or Adobe libraries
Adobe Firefly’s own models	Firefly image models	Brand-safe Adobe workflows, Content Credentials inside Adobe	Follow current Firefly terms	Cover for partner-model output

Flare is the default OpenAI API choice: higher quality than GPT-Image-2 at up to 50% lower latency. Sunburst is the slower model for production-ready campaign creative and polished product imagery. Firefly exposes those names as partner models. ChatGPT does not. If you are chatting in ChatGPT, you get Images 2.5. If you are in Firefly, pick the model in the dropdown and write down which one you used.

Volume is not a pass. Product photos still fail on warped labels. Ads still fail on invented prices.

Partner model rules that change the workflow

Adobe’s partner-model note matters more than the launch quote: these models are not Adobe-developed. Do not assume Firefly’s own-model commercial terms, indemnification, or Content Credentials behavior automatically cover a Flare or Sunburst file. Read the current partner-model help page and your plan’s generative terms before you send a file to a client, a store, or an ad account.

OpenAI still attaches C2PA metadata and an invisible watermark to GPT Image outputs. Downstream platforms may keep, strip, or flag that provenance. Do not call a file “clean” because it sat inside Firefly.

Native transparency is useful for stickers, infographic objects, and layout assets. It is the wrong export for most storefront banners and marketplace main images. Flatten when the destination fills transparency with black or junk.

Sketch (@Sketch) and ChatGPT templates such as Poster and Merch stay in ChatGPT. They are not a Firefly feature. In Firefly, start from text-to-image, Prompt to Edit Image, Style generator (Flare), or Boards.

Pick the surface from the job

Write the job in one sentence before you touch a model menu.

1. Catalog still. One SKU, one angle, empty label panel if type must be exact. Prefer Sunburst in Firefly, or GPT Image 2 if that is the generator in front of you.
2. Social ad still. Same object, new crop, empty headline band. Prefer Flare for many variants. Recrop later. Do not stretch a 1:1 catalog shot into 4:5.
3. Transparent asset. One object, crisp edge, no drop shadow unless you want it. Flare lists native transparency; Sunburst lists transparent-image quality. Export PNG or WebP if the API or Firefly gives you an alpha channel. Inspect the edge at 100%.
4. Face-preserving edit. Keep the person. Change only background, wardrobe, or light. Sunburst is the partner model Adobe tags for facial preservation. One noun per edit.
5. Style exploration. Flare is the one Adobe lists on Style generator. Lock the subject first. Style second. If style eats the product, discard the file.

If Firefly is not available in your region, or the partner model is missing from the dropdown, do not invent a workaround that relabels GPT Image 2 as 2.5. Use the model you actually have.

Creator workflow inside Firefly or GPT Image 2

Use the same sequence in Firefly, ChatGPT, or a GPT Image 2 workspace.

1. Name the slot. Amazon-style main image, 4:5 ad, 9:16 story, 2:3 poster, or cutout asset. One slot.
2. Name the model. Flare, Sunburst, GPT Image 2, ChatGPT Images 2.5, or an Adobe Firefly model. Write it in the file name.
3. Lock the brief. Subject, crop, background, lighting, what must not move, what type stays empty.
4. Generate three options on the same crop. Changing aspect ratio between option A and option B is a new job.
5. Edit one noun. “Keep the bottle. Change only the background to matte seamless white.” If the label warps, stop. Go back to the better base.
6. Overlay real words in an editor. Prices, dates, URLs, and legal lines never belong in the generator if they must be exact.
7. Export for the real slot. Flatten when the destination hates transparency. Recrop in the matching tool instead of stretching.
8. Review the pixels. Zoom to 100%. Check extra fingers, melted logos, fake seals, and whether provenance metadata is acceptable for that channel.

Prompt formula

Create a [catalog still / social ad still / poster concept / transparent cutout], not a collage and not a store screenshot.
Surface: Adobe Firefly partner model [GPT-Image-2.5 Flare / GPT-Image-2.5 Sunburst] or GPT Image 2.
Crop: [1:1 / 4:5 / 9:16 / 16:9 / 2:3].
Subject: [one real product, person, or object].
Materials: [accurate finish, color, and shape].
Background: [seamless white / real-use surface / transparent / empty poster field].
Lighting: [soft studio / window side light / even catalog light].
Reference rule: preserve [silhouette, label panel, handle, face identity]. Do not add [extra SKUs, badges, hands, invented packaging].
Text handling: leave a clean empty band for [headline / price / date]. No readable URLs, ratings, or logos.
Edit mode if this is a follow-up: change only [background / angle / shadow / style]. Keep everything else.
Must avoid: warped labels, fake certifications, celebrity likenesses, transparent corners unless this file is a cutout asset.

The two fields that matter after this Firefly listing are “surface” and “reference rule.” A partner-model dropdown will not save a vague “make it more premium” prompt.

Prompt examples you can copy

1. White-background catalog still in Sunburst

Create a catalog product still, not a lifestyle ad.
Surface: GPT-Image-2.5 Sunburst in Firefly, or GPT Image 2 if that is the generator in use.
Crop: 1:1.
Subject: one matte stainless water bottle, lid closed, no condensation, front label panel empty.
Background: seamless white, faint contact shadow only.
Lighting: even catalog light, no colored gels.
Reference rule: keep the bottle silhouette and lid thread. Do not add extra bottles, ice, gym equipment, or logos.
Text handling: no type.

Keep the materials honest in AI product photography or the white-background product photo tool. Sample a corner later if a marketplace wants pure white.

2. Fast ad variants in Flare

Create a 4:5 social ad still, not a poster and not a marketplace main image.
Surface: GPT-Image-2.5 Flare in Firefly.
Crop: 4:5.
Subject: the same water bottle on a kitchen counter, one bottle only.
Hero: bottle in the lower third, large empty band in the upper third for a two-word overlay later.
Lighting: window side light, realistic wood grain.
Text handling: empty headline band, no price, no URL, no “50% off”.
Must avoid: fake app UI, invented reviews, extra products.

Recrop the winner in AI social media ads. Generate three lighting variants. Do not change the bottle. If you later need a poster crop, start a new 2:3 brief in the AI poster generator instead of stretching the ad.

3. Transparent cutout for a layout

Create a single-object cutout asset, not a scene.
Surface: GPT-Image-2.5 Flare or Sunburst with transparent background.
Crop: 1:1.
Subject: the same water bottle, lid closed, front label empty.
Background: transparent, crisp edge, no halo, no drop shadow.
Lighting: even studio light.
Reference rule: keep the silhouette. Do not add a table, reflection, or second bottle.
Text handling: no type.
Export: PNG or WebP with an alpha channel. Inspect the edge at 100%.

Use a cutout in a layout tool. Flatten before you upload to a banner slot that fills transparency with black.

Limitations you should not skip

Firefly hosting OpenAI models does not make those files Adobe Firefly models. If a client asked for Firefly’s own-model terms, say which partner model you used.

Availability can vary by country or region. If Flare or Sunburst is missing, use GPT Image 2 or ChatGPT Images 2.5 and keep the names honest.

Better edits are not infinite edits. If turn four warps a face or a label, revert. Do not stack adjectives.

Transparency is a file setting, not a style. A “transparent look” on an opaque JPEG is still an opaque JPEG.

FreeGPTImg continues to offer GPT Image 2 generations with 20 daily free credits and no credit card required. That is a GPT Image 2 workspace. It is not a claim that GPT-Image-2.5 Flare or Sunburst is the on-site default. Match the model name to the tool you actually used.

Do not promise Amazon, Shopify, Meta, or Adobe-indemnity compliance from a prompt. Generate the still. Read the current listing, ads, and partner-model terms. Overlay only claims you can stand behind.

FAQ

Is GPT-Image-2.5 available in Adobe Firefly?

Adobe’s partner-model list, updated September 9, 2026, includes GPT Image 2.5 Flare and GPT Image 2.5 Sunburst for Firefly text-to-image, Prompt to Edit Image, and Firefly Boards. Flare is also listed on Style generator. Availability can vary by country or region.

Should I use Flare or Sunburst in Firefly?

Use Flare for fast variants, social drafts, style tests, and many transparent-asset tries. Use Sunburst when the still must keep a face, a product silhouette, or campaign-level polish. Write the model name into the file name so nobody relabels it later.

Does this replace GPT Image 2?

No. GPT Image 2 remains a separate model, including as a Firefly partner model and in other GPT Image 2 workspaces. Use 2.5 where you have it. Use GPT Image 2 where that is the generator in front of you.

Do partner models get Adobe’s own-model commercial terms?

Not automatically. Adobe says partner models are not developed by Adobe and that you are responsible for deciding whether a model fits the project. Read the current partner-model help page and your plan terms. Do not assume Firefly indemnification covers OpenAI output.

Can I use a Firefly transparent PNG as an Amazon main image?

Usually no. A marketplace main image is typically an opaque product photo on a specified background, not a cutout. Generate the catalog still opaque, or flatten a cutout onto pure white and inspect the file. Do not upload an alpha channel into a slot that forbids it.

Should I regenerate every GPT Image 2 asset today?

No. Regen when the old file fails a real job: warped label, wrong crop, or an edit that will not hold. Keep files that already passed review. A partner-model listing is not a reason to throw away a working catalog shot.
