What GPT Image 2.5 Changes

OpenAI shipped GPT Image 2.5 on September 8, 2026 in two API flavours — Flare and Sunburst. Both are wired into this page, and you never have to think about which endpoint you're hitting.

⚡

Flare: the fast default

OpenAI positions Flare as the default for most applications, delivering higher-quality images than GPT Image 2 at up to 50% lower latency. It's the tier we preselect for social posts, thumbnails, and high-volume runs.

🎯

Sunburst: precision editing

Sunburst trades speed for control across edits. Use it for production-ready campaign creative and polished product imagery where a small change must not disturb the rest of the frame.

🔁

Edits that hold across turns

The headline upgrade is multi-turn consistency: subjects, textures, and approved regions survive repeated edits far better, which is what kills most AI retouching workflows.

🖼️

Up to 16 reference images

Drop in a face, a product, and a style frame together. Reference fidelity improved in 2.5, so recognizable subjects stay recognizable instead of drifting into a lookalike.

🔤

Sharper text and layouts

Early testers singled out text rendering and complex layouts — useful for posters, packaging, and ad frames where a headline has to be readable, not decorative.

📐

1K to 4K, nine aspect ratios

Pick 1K for drafts and 4K for hero frames, across square, portrait, landscape, and 21:9 cinematic crops. Credits update live so the cost is never a surprise.

🚀

No mode switching

Most GPT Image 2.5 sites make you choose text-to-image or image-to-image first. Here you just write a prompt; uploading a reference is what turns a generation into an edit.

🍌

Next to the rest of your stack

GPT Image 2.5 sits beside Nano Banana and Seedance on NanoBananaTool, so a still can go straight from prompt to edit to video without leaving the workspace.

GPT Image 2.5 — Frequently Asked Questions

What shipped, how the two tiers differ, and how this page works.

  • Yes. OpenAI released it on September 8, 2026 — as ChatGPT Images 2.5 inside ChatGPT and as two API models, gpt-image-2.5-flare and gpt-image-2.5-sunburst. Both tiers are live on this page.
  • Flare is OpenAI's recommended default: the 2.5 quality and editing improvements at markedly lower latency, ideal for everyday and high-volume generation. Sunburst is the precision option for detailed creative work and takes longer to generate. On this page they're a single toggle, not two different products.
  • No, and that's deliberate. Write a prompt and we run text-to-image. Upload one or more reference images and the same button becomes an edit, using the matching GPT Image 2.5 endpoint behind the scenes.
  • Up to 16 per generation. Use one for a straightforward edit, or combine a subject, a product, and a style frame when you need the model to respect several constraints at once.
  • 1K, 2K, and 4K output across auto, 1:1, 3:2, 2:3, 4:3, 3:4, 16:9, 9:16, and 21:9. Higher resolutions may require a paid plan; locked options tell you which plan unlocks them before you spend anything.
  • The credit cost is shown on the generate button and updates as you change tier and resolution. Flare costs less per image than Sunburst, and 1K costs less than 4K — no hidden per-token maths.
  • OpenAI reports sharper detail, more natural lighting, better preservation of reference subjects, and more reliable multi-turn edits, with Flare running up to 50% faster than Images 2.0. GPT Image 2 is still available and has no announced retirement date, so keep it as your baseline while you compare on your own prompts.
  • Images you generate are yours to use within our terms and OpenAI's usage policies. For campaign work, review brand-sensitive details — small text, logos, and labels — before publishing, as with any generative model.
