GPT Image 2.6 on VdoBloom: Flare vs Sunburst, Credits and Limits

GPT Image 2.6 is live on VdoBloom in two variants, Flare and Sunburst. Generating an image costs 3 credits at 1K, 4 at 2K and 7 at 4K. Editing a photo costs 5 credits at 1K, 8 at 2K and 10 at 4K. Both variants cost the same: Flare is the faster one for everyday work, Sunburst is the precision one for detail, layout and text inside the image. Open the AI image generator or the AI photo editor and pick GPT Image 2.6 in the model list.

Updated 10 November 2026.

What changed from GPT Image 2.5

GPT Image 2.5 stays on VdoBloom, so you can use either. These are the differences that matter when you choose.

	GPT Image 2.5	GPT Image 2.6
Aspect ratios	auto + 12	auto + 15 (adds 5:4, 4:5, 2:1, 1:2, 9:21, 3:1, 1:3)
Ratios limited to 1K	Four (27:16, 16:27, 9:8, 8:9)	None
Prompt length	20,000 characters	32,000 characters
Photos per edit	16	16
Generate, 1K / 2K / 4K	3 / 5 / 8 credits	3 / 4 / 7 credits
Edit, 1K / 2K / 4K	3 / 5 / 8 credits	5 / 8 / 10 credits

Read the last two rows together. For making new images, 2.6 costs the same at 1K and less at 2K and 4K. For editing your own photos, 2.6 costs more than 2.5, so GPT Image 2.5 remains the lower-priced choice for edits. Four ratios that 2.5 had (27:16, 16:27, 9:8 and 8:9) are not in 2.6; if you rely on one of those, stay on 2.5 for that job.

Flare vs Sunburst

Variant	Built for	Speed in our tests	Credits
Flare	Everyday images and quick tries	About 20 to 35 seconds at 1K	Same as Sunburst
Sunburst	Fine detail, tight layouts, text that must be right	About 30 to 60 seconds at 1K	Same as Flare

The times are from our own test runs on 10 November 2026 and will vary with load. 4K takes longer on both: our 4K tests took roughly one to one and a half minutes. Because the two variants cost the same, the choice is only about speed against precision. Start with Flare, and switch to Sunburst when a result is close but a detail or a word is off.

Sizes and aspect ratios

You pick a resolution tier and an aspect ratio; the pixel size follows from the two. A few examples:

Ratio	1K	2K	4K
1:1	1024 x 1024	2048 x 2048	2880 x 2880
16:9	1536 x 864	2048 x 1152	3840 x 2160
9:16	864 x 1536	1152 x 2048	2160 x 3840
4:5	1024 x 1280	2048 x 2560	2576 x 3216
3:1	1536 x 512	3072 x 1024	3840 x 1280

The full list is auto, 1:1, 3:2, 2:3, 4:3, 3:4, 5:4, 4:5, 16:9, 9:16, 2:1, 1:2, 21:9, 9:21, 3:1 and 1:3. The new wide and tall ratios are useful for website banners (3:1), phone wallpapers and story backgrounds (9:21), and Instagram feed posts (4:5).

How to use it

Open the AI image generator to make a new image, or the AI photo editor to change a photo you upload.
Open the model list, choose the GPT Image family, then GPT Image 2.6 Flare or Sunburst.
Write your prompt. Put any words that should appear in the picture inside quotes.
Pick the aspect ratio and the resolution. The credit cost for your choice shows on the button before you start.
Generate. If the run fails, the credits come back on their own.

Prompts to try

Sign with exact words. “A cozy bookshop window at dusk, a hand-painted wooden sign that reads "OPEN LATE", warm lamp light inside, photo.” In our test Flare spelled the sign correctly on the first run.
Feed post, 4:5. “Flat-lay photo of a breakfast table from above, one plate of pancakes in the centre, a cup of coffee top right, linen napkin bottom left, soft morning light, empty space at the top for a caption.”
Website banner, 3:1. “Wide illustration of a mountain ridge at sunrise, three pine trees at the far right, empty sky across the left two thirds for a headline, muted teal and amber.”
Background swap (edit). Upload a portrait, then: “Keep the person exactly the same. Change the background to a sunny beach with palm trees.” In our test the subject, pose and outfit stayed unchanged.
Product with a label. “Studio photo of a matte black coffee jar on a pale oak shelf, label reads "SLOW ROAST" in thin capital letters, soft window light from the left, no other props.”

Getting better results

Say what stays the same when you edit. “Keep the face, hair and clothes unchanged” protects the parts you care about.
Count and place things. “Three jars, the front one sharp” works better than “a few jars”.
Draft at 1K, finish at 4K. Two 1K tries cost 6 credits, less than one 4K image. Only render 4K once the picture is right.
Use fewer photos when editing. One or two clear photos usually edit faster than many.

Frequently asked questions

How many credits does GPT Image 2.6 cost on VdoBloom?

Generating costs 3 credits at 1K, 4 at 2K and 7 at 4K. Editing costs 5 credits at 1K, 8 at 2K and 10 at 4K. Flare and Sunburst cost the same.

Is Sunburst more expensive than Flare?

No. Both variants have the same prices. Flare is faster; Sunburst is aimed at precision.

Should I use GPT Image 2.6 or 2.5?

For new images, 2.6: it has more aspect ratios, longer prompts, and costs the same or less. For editing photos, 2.5 costs fewer credits (3, 5 and 8), so try it first if price matters, and move to 2.6 when you want the newer model.

How many photos can I upload for one edit?

Up to 16.

Can I try it free?

New accounts get 10 free credits with no card, which covers three 1K images on GPT Image 2.6. Free downloads carry a watermark; it is removed after any credit pack or plan. See pricing for packs, which start at $10.39 for 200 credits that never expire.
