GPT Image 2.5 FAQ
Twelve questions we get most often — release date, free access, Flare vs Sunburst, prompts, pricing, and more.
When was GPT Image 2.5 released?
GPT Image 2.5 (ChatGPT Images 2.5) was released on September 8, 2026, together with two API models: gpt-image-2.5-flare and gpt-image-2.5-sunburst.
Is GPT Image 2.5 free?
In ChatGPT, image generation is available on every tier including Free, with usage limits that vary by plan. The API is pay-per-use: text input $5 per million tokens, image input $8 per million, image output $30 per million (same for both variants).
How do I access GPT Image 2.5?
Two ways: in ChatGPT, start a chat and choose the GPT Image 2.5 image model; or via the API using the model IDs gpt-image-2.5-flare or gpt-image-2.5-sunburst. Our how-to-access guide walks through both.
What is the difference between Flare and Sunburst?
Flare is the speed-optimized variant for fast, everyday generation (up to 50% lower latency than GPT Image 2, per OpenAI). Sunburst is the quality-first variant, strongest for strict product geometry, faces, dense typography, and long edit chains. They share the same token pricing.
How many prompts are on this site?
104 original prompts across 8 categories, all free to copy and use. No sign-up or payment is required.
Do I need an API key to use the prompt generator?
No. The generator runs entirely in your browser and assembles your prompt with plain JavaScript. It never calls an AI API, which is why it is free and instant.
Can GPT Image 2.5 render text in images?
Yes — layout and infographic accuracy improved in 2.5. Put the exact wording in double quotes inside your prompt, keep it short, and specify the type style (for example, bold condensed sans-serif).
What image sizes and aspect ratios are supported?
Common sizes are 1024×1024, 1536×1024, and 1024×1536, plus custom sizes: multiples of 16, up to 3,840 px per side, aspect ratio up to 3:1.
How long should a prompt be?
For most images, 50–120 words of structured detail outperform both one-liners and long essays. Follow the five-part formula: deliverable, subject, composition, visual direction, constraints.
Can I use these prompts and generated images commercially?
The prompts on this site are free for personal and commercial use. Images you generate are subject to OpenAI's terms of service and your local law — review them for your use case.
