GPT Image 2.5 on Image 2 — Flare, Sunburst & How to Use Them

GPT Image 2.5 is OpenAI’s successor to GPT Image 2 / ChatGPT Images 2.0. Announced September 8, 2026 as ChatGPT Images 2.5, the generation ships to developers as GPT-Image-2.5 Flare and GPT-Image-2.5 Sunburst. On Image 2, both routes live in the same generator you already use—so you do not rebuild prompts, references, or billing when you upgrade a run.

What changed with Images 2.5

OpenAI positions Images 2.5 around fidelity and control:

• Subjects from reference photos stay more recognizable
• Local edits are less likely to unwind the rest of the frame
• Multi-turn chains hold earlier instructions more reliably
• Latency can drop by up to about 50% versus Images 2.0

Those gains matter for social teams iterating daily and for marketers polishing a single campaign hero.

Flare vs Sunburst

• Flare — everyday quality for creator content, product frames, prototyping, and high volume. The fast default.
• Sunburst — campaign creative, polished product imagery, and tighter multi-turn edits. Usually longer generation.

On Image 2 you switch routes by changing the model field only. Credits, aspect ratios, and reference uploads stay shared.

A practical Image 2 loop

1. Write or load a prompt (gallery Use prompt works the same way)
2. Optionally attach up to 16 reference images
3. Pick Flare or Sunburst
4. Confirm credits and generate
5. Refine in history—or start a new edit turn

Failed jobs surface readable reasons so you revise instead of guessing. Favorites and published gallery pieces stay tied to your account across model upgrades, which keeps a reusable prompt library intact.

Prompting tips that still matter

• Describe subject, setting, and lighting before stacking style adjectives
• Quote exact on-image text in quotation marks
• Name layout hierarchy when posters or UI comps matter
• Prefer one local change per edit turn on Sunburst
• Start from a clear reference when identity or packaging must survive style shifts—GPT Image 2.5’s stronger preservation is built for that

Credits and pricing

Signup bonuses help you try GPT Image 2 and GPT Image 2.5. Packs and subscriptions live on the pricing page with clear per-image costs before you click generate. OpenAI publishes separate API token pricing for Flare and Sunburst; on Image 2, trust the credit total shown in the UI for that run.

Affiliation and safety

Image 2 is not affiliated with OpenAI. Model names describe generation capability; the product brand is Image 2. Safety measures such as prompt and image checks, C2PA metadata, and watermarking may still apply upstream—always review outputs before client delivery. AI images can be imperfect even when instruction following is strong.

Migrating from GPT Image 2

Keep your best prompts and references. Try the same brief on Flare first for speed and quality, then move stubborn edit chains to Sunburst. Explore the gallery for layout patterns, then open the generator on the GPT Image 2.5 landing page to run a test.

The goal is a short loop: inspire, generate, refine, save—now with Images 2.5 in the picker.
