Image generation powered by OpenAI's gpt-image-2.5-sunburst (GPT Image 2.5 Sunburst), the next-generation flagship image model after GPT Image 2, with sharper detail, richer lighting, better composition and stronger prompt adherence. Describe the picture you want in a few sentences and receive a high-resolution illustration or photo-style output; style, aspect ratio and subject are all controllable via prompt. A quality selector above the input box defaults to auto (the model decides from the prompt) and also offers low, medium, high, xhigh and max; higher levels render more detail and take longer. You can also upload up to sixteen pictures and edit them with plain-language instructions such as "replace the background with a city at night" or "change the jacket to red"; if the result is not quite right, just send another instruction and the previous output is reused for continuous refinement, and you can also upload another picture in the same conversation as a reference for editing the previous result. Great for marketing banners, slides, blog headers and product concept art. To compare styles, try GPT Image 2 or Nano Banana Pro as well. The generated image size is chosen automatically by the model from your prompt: commonly 1024x1024 (square), 1024x1536 (portrait), or 1536x1024 (landscape), and other resolutions are possible, with the longest edge up to 3840 pixels. Prompt example 1: Create a realistic product photo: a white ceramic mug on a marble table with scattered coffee beans, slanting morning light, shallow depth of field, fine textures. Prompt example 2: (Upload a photo of a living room) Swap the sofa for a dark green velvet one, repaint the walls off-white, and add a floor lamp; keep everything else the same. Prompt example 3: Portrait music festival poster: a lawn stage with string lights, fireworks in the night sky, the title Starry Music Fest on top and the date 8/16 below, cinematic light. Prompt example 4: Create a realistic interior render: a Scandinavian open kitchen with light oak cabinets, white quartz counters and three pendant lights, afternoon sun from a window on the right. Prompt example 5: Draw a portrait infographic titled Benefits of Drinking Water in four blocks: metabolism, kidney health, better skin, sharper focus, each with a simple icon, blue-green palette. Prompt example 6: Design the front of a craft beer can: deep blue with gold mountain lines, Starlight Brewing in the center and small text IPA 5.5% below, shown as a realistic 3D can. Prompt example 7: (Upload a model photo and four jewelry product photos) Have the model wear the necklace, earrings, watch and ring together, with the lighting of a luxury magazine cover. Prompt example 8: Create a cinematic film still: a middle-aged detective in a trench coat holding a black umbrella under neon signs on a rainy Taipei street at night, 35mm film look. Prompt example 9: Design a landscape homepage banner: Smart Warehouse Solutions and a one-line subtitle on the left, a realistic 3D automated warehouse with robot arms and conveyors on the right, tech blue tones. Prompt example 10: (Upload a photo of a ring) Remove fingerprints and dust from the metal, enhance the diamond's sparkle and reflections, and keep a pure white background for an online store.
