GPT Image 2.5 is the latest AI image generation model from OpenAI, available right here to use online — fast, free to preview, and with more control than the official app. Powered by the new flare engine, it generates high-quality images in seconds, supports up to 4K resolution, 15 aspect ratios, and lets you edit existing images by uploading reference photos. No subscription, no waitlist — just type a prompt and create. This page is also fully compatible with the previous GPT Image 2 model, and includes batch generation, multiple channels, and below-retail pricing groups that the official tool doesn't offer.
GPT Image 2.5 is OpenAI's newest image generation model. It builds on GPT Image 2 with a faster engine (branded "flare"), higher resolution (up to 4K), and more aspect ratio options. You can use it here in your browser without installing anything or paying for a subscription — just enter a prompt and it generates the image in seconds.
The main differences are speed and quality. GPT Image 2.5 uses the new flare engine, which generates images noticeably faster than GPT Image 2. It also supports higher resolution output (up to 4K) and 15 aspect ratios. GPT Image 2 remains a solid, popular option, and this page lets you use either model. If you need speed and sharp detail, 2.5 is the better choice.
Using GPT Image 2 or 2.5 here is simple. First, describe what you want in the prompt box. Second, optionally upload reference images to guide the style or edit an existing photo. Third, choose a channel and select your resolution (1K, 2K, or 4K) and aspect ratio. Fourth, click generate and download the result. No account is needed for trial, and batch generation is supported.
This page offers a free preview of GPT Image 2.5 so you can test the quality before paying. The full generation runs on credits or a paid plan, with below-retail pricing available in the special discount groups. Pricing depends on the resolution you choose — 1K is the cheapest, 4K costs more per image. Check the pricing table on this page for the current numbers.
To edit or modify an existing image, upload it as a reference image in the input area, then describe the change you want in the prompt (for example, "change the background to a beach" or "make this person smile"). GPT Image 2.5 understands the reference image and applies your edits while keeping the original subject. You can upload multiple references for more complex edits.
GPT Image 2.5 supports 15 aspect ratios, including 1:1 (square), 16:9 (widescreen), 9:16 (portrait/vertical), 4:3, 3:4, and more. You can pick the ratio that matches your use case — square for social posts, 16:9 for thumbnails and presentations, 9:16 for Stories and Reels.
These are output resolution levels. 1K is the base resolution and is the fastest and cheapest to generate — good for quick previews. 2K gives a noticeable boost in sharpness, ideal for most web use. 4K is the highest quality, best for printing or large displays, but takes longer and costs more credits per image. Choose based on how you plan to use the image.
Yes. GPT Image 2.5 on this page supports batch generation, so you can create multiple images in one go and download them together. Use the "batch" option after entering your prompt, and the generator will produce a set of variations based on your input.
