Question 1

What is GPT Image 2.5?

Accepted Answer

GPT Image 2.5 is OpenAI's image model released on September 8, 2026. It comes as two models: GPT Image 2.5 Flare, optimized for speed, and GPT Image 2.5 Sunburst, optimized for precision. Both take text and image inputs and output images. In ChatGPT the same upgrade is called ChatGPT Images 2.5.

Question 2

GPT Image 2.5 Sunburst vs Flare: which should I use?

Accepted Answer

Start with Flare. OpenAI calls it the default for most applications, with higher quality than GPT Image 2 at 50% lower latency, so it suits drafts, social content and batches. Switch to Sunburst when a single image needs careful work, such as a campaign hero image or a product shot you are editing in several steps. It takes longer per image in exchange for tighter control.

Question 3

What is GPT Image 2.5 Sunburst?

Accepted Answer

Sunburst is the quality-first GPT Image 2.5 model. OpenAI describes it as built for premium visual workflows that benefit from tighter control across edits, with longer generation times. In LazyKiwi it costs the same credits as Flare.

Question 4

What is GPT Image 2.5 Flare?

Accepted Answer

Flare is the speed-first GPT Image 2.5 model and OpenAI's default recommendation. OpenAI says it produces higher-quality images than GPT Image 2 at 50% lower latency and suits creator content, product experiences, rapid prototyping and high-volume generation.

Question 5

When was GPT Image 2.5 released?

Accepted Answer

OpenAI announced ChatGPT Images 2.5 and released GPT Image 2.5 Flare and GPT Image 2.5 Sunburst in its API on September 8, 2026. Both variants are available in the LazyKiwi image generator.

Question 6

How much does GPT Image 2.5 cost on LazyKiwi?

Accepted Answer

LazyKiwi charges credits per image by resolution, and Flare and Sunburst cost the same: 13 credits at 512 or 1K, 17 at 2K and 20 at 4K. Those prices are currently discounted from 130, 130, 170 and 200 credits. The Generate button shows the exact cost before you run a prompt, and plans are listed on the pricing page.

Question 7

Is there a GPT Image 2.5 API on LazyKiwi?

Accepted Answer

No. LazyKiwi is a web workbench, not an API reseller: you use GPT Image 2.5 in the browser from the image generator. If you want to call the model from your own code, OpenAI offers both GPT Image 2.5 Flare and Sunburst in its own API, with pricing published by OpenAI.

Question 8

How is GPT Image 2.5 different from GPT Image 2?

Accepted Answer

OpenAI says Images 2.5 produces more natural lighting and richer textures, preserves subjects from reference photos better, and follows edit instructions more reliably across several turns. Flare in particular generates higher-quality images than GPT Image 2 at 50% lower latency. GPT Image 2 is still available in LazyKiwi if you want to match older work.

Question 9

Can I edit my own photo with GPT Image 2.5?

Accepted Answer

Yes. In the image generator, upload a reference image next to your prompt and describe the change, such as a new background or a different setting. OpenAI says Images 2.5 is better at changing only what you ask for while keeping the rest of the image the same.

Question 10

What sizes and aspect ratios does GPT Image 2.5 support in LazyKiwi?

Accepted Answer

You can choose 16:9, 9:16, 1:1, 4:3 or 3:4, and a resolution of 512, 1K, 2K or 4K. Higher resolutions cost more credits per image.
