# GPT Image 2.6 Sunburst GPT Image 2.6 Sunburst is OpenAI's image model for detailed work and precise edits, released with GPT Image 2.6 Flare on 4 November 2026. In Sloosh it takes a prompt and up to 16 reference images, renders at 1K, 2K or 4K, and offers five quality levels up to max. It also makes animated GIFs and SVG files.

OpenAI's model page names detailed compositions and image editing workflows as this model's job ([OpenAI](https://developers.openai.com/api/docs/models/gpt-image-2.6-sunburst)). - Edits that need precision. OpenAI calls Sunburst "the base model for workflows that need more detail or precise edits" ([OpenAI image prompting guide](https://developers.openai.com/api/docs/guides/image-prompting)). - Composites built from several references (a product, a model, a background), since Sloosh accepts up to 16 per generation. - Labels and packaging: the Label Designer Space ([sloosh.ai/spaces/label-designer](https://sloosh.ai/spaces/label-designer)) and Packaging Mockup Pack Space ([sloosh.ai/spaces/packaging-mockup-pack](https://sloosh.ai/spaces/packaging-mockup-pack)) fit this job. - Short looping GIFs for social posts, stickers and reactions. Describe the subject, the motion and the loop in the prompt ([OpenAI image generation guide](https://developers.openai.com/api/docs/guides/image-generation)). - Logos and icons as SVG, which you can scale or recolor by editing the paths ([OpenAI image prompting guide](https://developers.openai.com/api/docs/guides/image-prompting)). ## How to use GPT Image 2.6 Sunburst in Sloosh 1. Open [Image Studio with Sunburst selected](https://sloosh.ai/studio/image?image-model=gpt-image-2.6-sunburst), or pick GPT Image 2.6 Sunburst in the model chip. 2. Add references if you have them (up to 16): from the drawer, by pasting, or with Use as reference on an earlier result. 3. Write the prompt. Name each reference by number and job, for example "Image 1: product photo". 4. Set aspect ratio, resolution (1K, 2K or 4K) and quality (low to max). 5. For an animated GIF or a vector SVG, pick it under Format. 6. Check the cost on the Generate button, then generate. ## GPT Image 2.6 Sunburst prompting tips - Moving from GPT Image 2.5 Sunburst? OpenAI suggests trying 2.6 Sunburst first with the same work ([OpenAI](https://developers.openai.com/api/docs/guides/image-prompting)). - Once Sunburst gives you what you need, try the same prompt, references and quality on Flare. OpenAI suggests this because Flare is built for speed ([OpenAI](https://developers.openai.com/api/docs/guides/image-prompting)). - For a GIF, describe the subject, the motion and how the loop ends. Nine frames at 200 ms each make a 1.8 second loop ([OpenAI](https://developers.openai.com/api/docs/guides/image-generation)). ## GPT Image 2.6 Sunburst example prompts **Prompt 1** ```text Image 1: a product photo of a ceramic mug. Place this exact mug on a linen tablecloth by a window with soft morning light. A small plate of biscuits sits behind it, slightly out of focus. Vertical image for a product page. Keep the mug's shape, glaze and handle exactly as in image 1. ``` **Prompt 2** ```text Change only the label text in image 1 from "DAILY GLOW" to "NIGHT REPAIR", same typeface, size and colour. Keep the jar, the lid, the lighting and the background of image 1 unchanged. ``` **Prompt 3** ```text Image 1 is the jacket. Image 2 is the model. Put the jacket from image 1 on the model in image 2, zipped halfway. Change only her top. Keep her face, hair, pose, the background and the light exactly as in image 2. ``` ## How it compares in Sloosh | Model | Resolution | Quality levels | References | Prompt | | --- | --- | --- | --- | --- | | GPT Image 2.6 Sunburst | 1K, 2K, 4K | low to max (5) | 16 | 32,000 | | [GPT Image 2.6 Flare](https://sloosh.ai/models/gpt-image-2.6-flare) | 1K, 2K, 4K | low to max (5) | 16 | 32,000 | | [GPT Image 2.5 Sunburst](https://sloosh.ai/models/gpt-image-2.5-sunburst) | 1K, 2K, 4K | low to max (5) | 16 | 32,000 | | [GPT Image 2](https://sloosh.ai/models/gpt-image-2) | 1K, 2K, 4K | low, medium, high | 16 | 32,000 | OpenAI calls Flare "the smaller model for workflows where speed matters most" and Sunburst the one for more detail or precise edits ([OpenAI](https://developers.openai.com/api/docs/guides/image-prompting)). ## Where else it runs - OpenAI API, model GPT Image 2.6 Sunburst, with image generation and image edit endpoints (OpenAI model page, accessed 2026-11-05). ## Frequently asked questions ### What is GPT Image 2.6 Sunburst? OpenAI's image model for detailed compositions and precise edits, released on 4 November 2026 ([OpenAI](https://developers.openai.com/api/docs/changelog)). In Sloosh it makes 1K, 2K or 4K images from a prompt and up to 16 references. ### What is GPT Image 2.6? OpenAI's image release of November 2026, in two API models: Sunburst for detail and Flare for speed. ### Sunburst or Flare: which should I use? OpenAI calls Flare the smaller model for speed and Sunburst the one for more detail or precise edits. Start with Sunburst, then try [Flare](https://sloosh.ai/models/gpt-image-2.6-flare) on the same work if the result holds. ### How is GPT Image 2.6 Sunburst different from GPT Image 2? It came out in November 2026, seven months after [GPT Image 2](https://sloosh.ai/models/gpt-image-2). In Sloosh both take 16 references and render up to 4K, and Sunburst adds xhigh and max quality. ### Can I use GPT Image 2.6 Sunburst without an API key? Yes. In Sloosh you pick it in Image Studio; the exact price shows on the Generate button before you run it. ### Is GPT Image 2.6 better than 2.5? OpenAI's guide says to try 2.6 Sunburst first for work you ran on [2.5 Sunburst](https://sloosh.ai/models/gpt-image-2.5-sunburst). In Sloosh both have the same settings, so you can compare them on one prompt. ### Can GPT Image 2.6 make GIFs? Yes. Pick GIF under Format in Sloosh, then set the frame size, frame count and frame duration. A GIF can run up to 16 frames. ### Can GPT Image 2.6 make SVG files? Yes. Pick SVG under Format in Sloosh. It writes a static vector file you can scale and recolor. SVG works from a prompt only, so it isn't offered once a reference image is attached. ## Related - Models: [GPT Image 2.6 Flare](https://sloosh.ai/models/gpt-image-2.6-flare), [GPT Image 2.5 Sunburst](https://sloosh.ai/models/gpt-image-2.5-sunburst), [GPT Image 2](https://sloosh.ai/models/gpt-image-2), [Nano Banana Pro](https://sloosh.ai/models/gemini-3-pro-image-preview) - Spaces: [Label designer](https://sloosh.ai/spaces/label-designer), [Packaging mockup pack](https://sloosh.ai/spaces/packaging-mockup-pack) ## Sources - [OpenAI: GPT Image 2.6 Sunburst model page](https://developers.openai.com/api/docs/models/gpt-image-2.6-sunburst) - [OpenAI: API changelog](https://developers.openai.com/api/docs/changelog) - [OpenAI: Image prompting guide](https://developers.openai.com/api/docs/guides/image-prompting) - [OpenAI: Image generation guide](https://developers.openai.com/api/docs/guides/image-generation) - [OpenAI: Introducing Images 2.6](https://openai.com/index/introducing-images-2-6/)
