GPT Image 2.6 Sunburst Text-to-Image generates high-quality images from natural-language prompts with a focus on precision, visual fidelity, and consistent detail, making it suitable for polished creative work, brand assets, product imagery, and production workflows. Ready-to-use REST inference API.

Features

OpenAI GPT Image 2.6 Sunburst Text-to-Image turns natural-language prompts into high-quality images. Sunburst is the precision-focused GPT Image 2.6 tier: it takes longer per image for higher fidelity and steadier details across repeated edits.


Why Choose This?

  • Strong prompt fidelity Generate images that closely follow detailed natural-language instructions, including scene layout, visual style, and composition.

  • Accurate text rendering Create images with clearer, more usable in-image text for posters, ads, packaging, and interface mockups.

  • Quality and complexity controls quality sets the rendering detail you pay for; complexity sets how much the model plans the layout before drawing, at no extra cost.

  • Animated GIF and vector SVG output Set output_format to gif for a looping animation of 2 to 16 frames, or to svg for a scalable vector file — icons, logos, flat illustrations.

  • Up to 4K output and flexible aspect ratios Square, portrait, landscape, and panoramic outputs at 1k, 2k, or 4k.

  • Production-ready API Access the model through a ready-to-use REST inference API for fast integration into applications and workflows.


Parameters

ParameterRequiredDescription
promptYesText description of the desired image.
aspect_ratioNoAspect ratio: 1:1, 3:2, 2:3, 3:4, 4:3, 4:5, 5:4, 9:16, 16:9, 21:9, 2:1, 1:2, 3:1, 1:3, 9:21. Defaults to 1:1.
resolutionNoOutput resolution: 1k (default), 2k, or 4k.
qualityNoQuality tier: low, medium (default), high, xhigh, or max. Higher tiers add detail and cost more.
complexityNoPlanning before drawing: low, medium, or high (default). Higher values help detailed, multi-element prompts and take a little longer; the price is the same.
output_formatNopng (default), jpeg, webp, gif (animated), or svg (vector).
frame_countNoGIF only: number of frames, 2 to 16 (default 9).
frame_duration_msNoGIF only: how long each frame shows, 20 to 2000 ms (default 200).

How to Use

  1. Write your prompt — describe the image in detail, including subject, style, lighting, composition, and any text you want to appear.
  2. Pick quality and resolution (optional) — medium / 1k is the default; raise quality for more detail or resolution for larger output.
  3. Lower complexity for simple requests (optional) — high is the default; low or medium returns a little faster on short, simple prompts.
  4. Choose aspect ratio (optional) — 1:1 for square, 2:3 or 9:16 for portrait, 3:2 or 16:9 for landscape, up to 3:1 / 1:3 panoramas.
  5. Submit — run the model and download your generated image.

Example Prompt

A cinematic product photo of an unbranded perfume bottle on a marble surface, soft golden-hour lighting, shallow depth of field, elegant reflections, premium editorial photography style


Pricing

Pricing varies by quality and resolution. complexity does not change the price.

Quality1k2k4k
low$0.045$0.075$0.135
medium$0.075$0.13$0.225
high$0.09$0.15$0.27
xhigh$0.16$0.27$0.48
max$0.36$0.60$1.00
  • GIF: the image price × (1 + frame_count / 16) — for example $0.117 for 9 frames at medium 1k.
  • SVG: the image price + $0.015.

Notes

  • prompt is the only required field.
  • GIF and SVG output are available on text-to-image only.
  • Requests containing sexual content are rejected before generation and are not charged.
