OpenAI's most advanced AI image generator. Create 4K images from text or edit photos with AI using GPT Image 2.5. Sunburst & Flare variants, transparent backgrounds, and 13 aspect ratios.
Every image below was created with GPT Image 2.5 in this playground — two portraits generated from text prompts, and two photos edited with natural language instructions using GPT Image 2.5 image to image.

Prompt: “Cinematic studio portrait of a confident female entrepreneur in her early 30s, tailored charcoal blazer, dramatic golden rim lighting, deep teal backdrop, 85mm editorial photography.”

Prompt: “Candid lifestyle portrait of a young man laughing warmly at golden hour in a city park, soft natural sunlight through autumn leaves, shallow depth of field, documentary style, 50mm lens.”
Before
AfterPrompt: “Replace the background with a softly blurred modern glass office with warm bokeh lights. Keep her face, hairstyle, pose and outfit exactly the same.”
Before
AfterPrompt: “Transform into a professional corporate headshot — navy suit, crisp white shirt, neutral light-gray studio backdrop, soft even lighting. Keep his face and smile exactly the same.”
Try these prompts yourself in the GPT Image 2.5 playground above — switch between Sunburst and Flare, or upload your own photo to edit.

GPT Image 2.5 is OpenAI's most advanced AI image generation model, released in 2026 as the successor to GPT Image 2. GPT Image 2.5 upgrades every part of the pipeline: native 4K resolution output, transparent background generation, 13 aspect ratios including cinematic 21:9, and two specialized variants — GPT Image 2.5 Sunburst and GPT Image 2.5 Flare. Whether you need text-to-image creation or image-to-image editing, GPT Image 2.5 delivers professional results in seconds.
On this page you can try GPT Image 2.5 free — no setup required. Generate images from text prompts, upload photos for AI editing, switch between Sunburst and Flare variants, and download watermark-free results in up to 4K resolution.
GPT Image 2.5 text to image generation turns detailed descriptions into high-fidelity visuals. The model accepts prompts up to 20,000 characters, so you can describe complex scenes, brand guidelines, typography requirements, and composition notes in a single request. GPT Image 2.5 then renders photorealistic images with the industry-leading text rendering the GPT Image family is known for — logos, posters, and UI mockups come out with correctly spelled, readable text.
Choose from 13 aspect ratios: auto, 1:1, 3:2, 2:3, 16:9, 9:16, 4:3, 3:4, 21:9, 27:16, 16:27, 9:8, and 8:9. That covers Instagram posts, YouTube thumbnails, website hero banners, print layouts, and ultrawide cinematic frames — all from the same GPT Image 2.5 online playground.
GPT Image 2.5 image to image editing lets you upload up to 10 reference images and describe the transformation you want. Change styles, replace backgrounds, remove objects, restyle products, or merge concepts across multiple inputs. Unlike older editors that require masks and layers, GPT Image 2.5 works entirely through plain-language instructions like "make the background a sunset beach" or "turn this into a watercolor painting."
A standout workflow is background removal: set the background option to transparent and GPT Image 2.5 returns a clean transparent PNG ready for e-commerce listings, stickers, and design composites — no Photoshop required.
OpenAI ships GPT Image 2.5 in two variants with identical APIs and pricing: GPT Image 2.5 Sunburst and GPT Image 2.5 Flare. The variants differ in their aesthetic tuning — Sunburst tends toward bright, high-energy compositions with punchy contrast, while Flare leans into softer, more naturalistic lighting and gradients.
The best approach is A/B testing: our playground has a one-click variant switcher, so you can submit the same prompt to both GPT Image 2.5 Sunburst and GPT Image 2.5 Flare and pick the output that fits your brand. Both variants support the full parameter set: 4K resolution, transparent backgrounds, and all 13 aspect ratios.
Comparing GPT Image 2.5 vs GPT Image 2, the headline upgrade is resolution: GPT Image 2.5 generates natively at 1K, 2K, and 4K, while GPT Image 2 tops out at 2K. GPT Image 2.5 also adds native transparent background output, doubles the aspect ratio selection from 6 to 13 options, introduces the Sunburst and Flare variants, and improves fine detail rendering in skin, fabric, and typography.
GPT Image 2 remains a solid, lower-cost choice for standard-resolution work. But for print-quality output, product photography with transparent backgrounds, or ultrawide 21:9 compositions, GPT Image 2.5 is the clear upgrade.
In the GPT Image 2.5 vs Nano Banana comparison, each model has clear strengths. GPT Image 2.5 leads in photorealism, prompt adherence, and in-image text rendering — the reasons the GPT Image family dominates marketing and design work. Nano Banana models (powered by Google) are strong at fast iteration and multi-reference consistency.
With GPT Image 2.5 now supporting 4K resolution, transparent PNGs, and up to 10 reference images, most of Nano Banana's former advantages have closed. For a detailed feature-by-feature breakdown, see the comparison table above.
GPT Image 2.5 4K generation produces images suitable for large-format print, retina displays, and professional product catalogs. Resolution is a single click (1K, 2K, 4K), and credit cost scales with quality — 1 credit for 1K, 2 for 2K, 3 for 4K — so you only pay more when you need more pixels.
Note that the 27:16, 16:27, 9:8, and 8:9 aspect ratios support 1K resolution only; 2K and 4K are available for all other ratios. When generating transparent backgrounds at 2K or 4K, include an instruction describing an isolated subject for the cleanest cutout.
The GPT Image 2.5 API uses an async job pattern: create a task with your prompt and parameters, then poll for the result URL. Both Sunburst and Flare variants expose the same contract — prompt, aspect_ratio, resolution, and background for text-to-image, plus input image URLs for image-to-image. Every playground feature on this page maps 1:1 to the GPT Image 2.5 API, so what you test here is exactly what you can automate.
