Meet GPT Image 2.6 Sunburst and Nano Banana Pro
GPT Image 2.6 Sunburst is OpenAI's GPT Image 2.6 model for detailed visual work: brand and B2B creative, product imagery and text-heavy layouts, tuned by reasoning effort and temperature. Nano Banana Pro is Google DeepMind's top-tier image model, known for 4K images with precise multilingual text and a thinking budget control. Both generate and edit at up to 4K from text and source images. Try them both in our AI Playground.
Text rendering: layouts vs multilingual text
Both models put readable text into images, with a different emphasis. GPT Image 2.6 Sunburst is built for text-heavy layouts such as posters, menus, packaging and infographics, where long copy and complex layouts have to hold together. Nano Banana Pro is known for precise multilingual text in its 4K output. For dense layouts, try Sunburst at a higher reasoning effort; for text in several languages, try Nano Banana Pro.
Reasoning effort vs thinking budget
Both models let you decide how much reasoning goes into an image. GPT Image 2.6 Sunburst uses reasoning effort, from low to max, with high as the default. Nano Banana Pro uses a thinking budget from 128 up to 24,576, starting at 128. Sunburst adds temperature (0 to 2) to explore more variation on the same prompt; Nano Banana Pro adds a seed, so you can repeat a result.
Editing with up to 16 or 14 source images
Both generate from text or edit and combine images you upload. GPT Image 2.6 Sunburst accepts up to 16 source images, and OpenAI built it to keep details more consistent from one edit to the next. Nano Banana Pro accepts up to 14. For multi-step edits on the same visual, Sunburst is built for consistency; for blending many images, both give you plenty of room.
Both reach 4K, with different outputs
Both render at 1K, 2K or 4K: Nano Banana Pro starts at 2K by default, Sunburst at 1K. Each offers eight aspect ratios; Sunburst includes 3:2, Nano Banana Pro includes 21:9 for wide banners. Sunburst also lets you choose a transparent background and export as PNG, JPEG or WebP, handy for product cutouts and design assets. Both generate up to 10 images per run.
Choose GPT Image 2.6 Sunburst or Nano Banana Pro
Choose GPT Image 2.6 Sunburst for brand, product and text-heavy layouts, transparent assets and consistent multi-step edits. Choose Nano Banana Pro for 4K images with multilingual text, wide 21:9 framing and repeatable results with a seed. Need speed instead? GPT Image 2.6 Flare is the faster GPT Image 2.6 model. Or use both: in Picsart's AI Playground you can run the same prompt through each and keep the better image.
