GPT Image 2.5 Generator, Successor to GPT Image 2

GPT Image 2 is the OpenAI image model behind ChatGPT Images 2.0, released in April 2026. MacRumors reported it as OpenAI’s first image model with thinking, with better text in scripts such as Japanese, Korean, Chinese, Hindi and Bengali, and images up to 2K.

On September 8, 2026 OpenAI followed it with GPT Image 2.5 in two variants. fal’s model page sums them up: "Flare is the default for most work, at higher quality than GPT Image 2 with half the latency. Sunburst spends longer to hold intricate detail." Both cost the same. Wikipedia’s history of the model lists the same dates.

This page runs those two variants through fal.ai. It does not run version 2 itself, so if you need that exact model, use OpenAI’s own products or API. The name stays on this page because most people still search for the model by that name.

Start on Sunburst. It holds fine detail and small type: botanical drawings, many lines of small print or a layout you will look at closely. It usually takes 25 to 50 seconds here and costs the same as Flare, which is why every AI design page on Pack AI Studio starts on it.

Switch to Flare when speed matters more than detail: quick drafts, bold posters and simple labels, usually in 20 to 40 seconds. In our own test on October 9, 2026 it made a packaging design in about 25 seconds and printed "MOSS & CO" and "NET WT 4 OZ (113 g)" correctly.

Credits: 10 an image at 1K, 12 at 1.5K and 15 at 2K, 1 to 4 images a run, for either variant. Size: about 1, 2.4 or 4.2 megapixels; fal allows larger files, but 2K is the largest size we offer. Shapes: all 11 aspect ratios from 21:9 to 9:21, inside the model’s 3:1 limit. Quality is always set to high.

References: up to 4 images here, such as a logo or a product photo. fal accepts more, but each reference adds to the cost of a run, so we keep the number low and the price fixed. Output is one PNG per image, not a layered file.

Credits come with the plans on pricing. If a run fails, takes too long or an image is not made, its credits go back to your balance.

Seedream 5.0 Pro (ByteDance) costs 11 credits at 1K or 1.5K and 22 at 2K, takes up to 10 references and is the pick for photo real materials and crowded layouts. Nano Banana 2.1 (Google) costs 8 or 11 credits, takes up to 10 references and is built for editing from photos; it has no 9:21. Muse Image (Meta) makes a 2 credit draft at one size, about 2.5 megapixels, and is best kept to short words.

So Flare and Sunburst are the default whenever text decides the job. Try the others on their own pages: Seedream 5.0, Nano Banana 2 and Muse Image.

Quote everything that must print, once. The text fields do this for the brand, product name, net quantity and tagline; for extra lines, put them in double quotes in the description, as in "ISSUE 02". Words outside quotes are a description the model may reword.

Write the net quantity the way it must appear. On US food packages it sits in the bottom 30% of the front panel in bold type (21 CFR 101.7) and gives both US and metric units (15 U.S.C. 1453), such as "NET WT 32 OZ (907 g)". The model copies what you type, so type it right.

Fewer, larger lines read better than a paragraph. Keep ingredient lists, Nutrition Facts and barcodes out of the image and build them exactly with our free nutrition label generator, food label maker and UPC barcode generator.

Treat the PNG as artwork, then place it on a real dieline from our free dieline generator and keep text inside the safe area. To design a whole box on its dieline from the start, use AI packaging design, which sends the flat dieline to the model as a reference; Sunburst is its default model too.
