Features of GPT Image 2

Native 4K Resolution

Generate up to 4K images without upscaling artifacts. Perfect for large-format print, hero banners, and retina-ready product photography that stays crisp when zoomed.

16-Image Reference Control

Blend up to 16 reference images in a single image-to-image call. Mix brand photography, mood boards, and product shots so the model locks onto the exact visual direction you need.

20,000-Character Prompts

Give the model room to breathe. Stack shot list, lighting brief, wardrobe notes, and on-image copy in one prompt — no more trimming instructions to fit a tiny token window.

Production-Ready Aspect Ratios

Six ratios covering every modern canvas: Auto for model-decided framing, 1:1 squares, 9:16 vertical for TikTok and Reels, 16:9 for YouTube and hero sections, plus 4:3 and 3:4 for editorial layouts.

Flagship Detail Fidelity

Sharper micro-details, more coherent textures, and better typography rendering than previous OpenAI image models. Built for work that will be scrutinized by art directors, not scrolled past.

Same Generator, Same Credits

Drop GPT Image 2 into the exact workflow you already use. Same generator UI, same credit system, same T2I and I2I tools — only the output quality changes.

Frequently Asked Questions

Find answers to common questions about this model

GPT Image 2 is OpenAI's flagship next-generation image generation model. It introduces native 4K output, six production-ready aspect ratios, up to 16 reference images for image-to-image, and a 20,000-character prompt budget — making it OpenAI's most capable image model to date.

GPT Image 2 adds native 4K rendering (1.5 is single-resolution), six aspect ratios covering vertical social and landscape formats (1.5 has three), support for 16 reference images per image-to-image call (1.5 takes one), and a 20K-character prompt window. It's positioned as flagship quality while 1.5 stays the speed-optimized option.

Six: Auto (model picks), 1:1 (square), 9:16 (vertical — TikTok, Reels, Stories), 16:9 (landscape — YouTube, hero banners), 4:3 and 3:4 (editorial and magazine layouts). This covers every major modern canvas.

Yes. GPT Image 2 supports native 1K, 2K, and 4K resolutions. Note two API constraints: Auto aspect ratio is rendered at 1K only, and 1:1 squares support 1K and 2K but not 4K. For all other aspect ratios, 1K / 2K / 4K are all available.

Up to 16 reference images per call, in JPEG, PNG, or WebP. This is ideal for blending style references, mood boards, product shots, and character references in a single generation.

Up to 20,000 characters. Plenty of room for shot lists, lighting notes, wardrobe direction, on-image typography, and scene-by-scene briefs — no more trimming ideas to fit a small token window.

Pricing is tiered by output resolution: 1K = 6 credits, 2K = 8 credits, 4K = 12 credits. Text-to-image and image-to-image are priced the same within each tier.

Use GPT Image 2 when output quality, resolution, or reference-image count matters — final assets, print, multi-reference brand work. Use GPT Image 1.5 when you need fast, low-cost iterations and the simpler three-aspect set is enough.
