🌞 GPT Image 2.5 Sunburst Text to Image

GPT Image 2.5 Sunburst turns prompts up to 20000 characters into bright, detail-dense imagery across 13 aspect ratios (including ultra-wide 21:9 and 27:16), with 1K / 2K / 4K resolution as the billing tier.

What is GPT Image 2.5 Sunburst Text to Image?

GPT Image 2.5 Sunburst Text to Image on FuseAITools (gpt-image-2-5-sunburst-text-to-image) is the Sunburst variant of the 2.5 family: required prompt (≤20000 chars), 13 aspect ratios, 1K / 2K / 4K resolution as the billing dimension, and optional background handling at 1K for cut-out-ready assets.

🌟 GPT Image v2 & 2.5 on FuseAITools

GPT Image on FuseAITools covers OpenAI's v2 and 2.5 Flare / Sunburst image models, all with 20000-character prompt capacity and selectable 1K/2K/4K resolution as the billing tier. The 2.5 families expand framing to 13 aspect ratios and add an optional background control at 1K, while image-to-image accepts up to 16 reference images.

✨ GPT Image v2 & 2.5 Core Features

20000-Character Prompts

Dramatically increased prompt capacity from v1.5—write detailed scene descriptions, multi-paragraph instructions, or storyboard treatments that the model follows with precision.

1K / 2K / 4K Resolution

Select your output resolution: 1K for fast drafts, 2K for standard quality, or 4K for maximum detail. Credit costs scale with resolution: 6 / 9 / 12 respectively.

Six Aspect Ratios + Auto

Choose from auto, 1:1, 9:16, 16:9, 4:3, 3:4—covers everything from vertical social posts to cinematic landscape framing. The "auto" option optimizes framing for your content.

13 Ratios on 2.5 Flare / Sunburst

The 2.5 models add 3:2, 2:3, 21:9, 27:16, 16:27, 9:8, 8:9 to the v2 set—13 aspect ratios in total. The four extreme ratios are gated to 1K and are disabled in the form at 2K / 4K.

Background Control at 1K

2.5 Flare and Sunburst accept an optional transparent / opaque / auto background, making cut-out-ready assets without a separate matting step. Only available at 1K; unset it to keep the server default.

Multi-Reference Editing (≤16)

Upload up to 16 images in the I2I workflow and prompt GPT Image v2 to fuse visual elements from all references into a single coherent generation.

❓ FAQ (GPT Image v2 & 2.5)

When should I pick GPT Image 2.5 Sunburst over Flare for text-to-image?

Both share the same control surface (20000-char prompt, 13 ratios, 1K–4K resolution billing, 1K-only background), so treat them as two stylistic variants of the 2.5 family. Generate the same prompt on both and keep the output that matches your brief—credits follow the resolution tier you select.

⚙️ GPT Image v2 & 2.5 Technical Specs

Parameters below match the FuseAITools GPT Image form and API (gpt-image-2-* and gpt-image-2-5-* models).

Workflow	Input	Aspect ratios	Resolution & credits	Key controls
v2 Text to Image	Prompt ≤20000 chars	auto, 1:1, 9:16, 16:9, 4:3, 3:4	1K 6 / 2K 9 / 4K 12	Prompt + resolution + aspect ratio
v2 Image to Image	Up to 16 image URLs + prompt ≤20000 chars	auto, 1:1, 9:16, 16:9, 4:3, 3:4	1K 6 / 2K 9 / 4K 12	Prompt + resolution + aspect ratio + up to 16 reference images
2.5 Flare Text to Image	Prompt ≤20000 chars (required)	13 ratios: auto, 1:1, 3:2, 2:3, 4:3, 3:4, 16:9, 9:16, 21:9, 27:16, 16:27, 9:8, 8:9	1K / 2K / 4K — resolution is the billing tier	Prompt + resolution + 13 ratios + background (1K only)
2.5 Flare Image to Image	Up to 16 image URLs (optional) + prompt ≤20000 chars	Same 13 ratios as Flare T2I	1K / 2K / 4K — resolution is the billing tier	Prompt + resolution + 13 ratios + background (1K only) + ≤16 references
2.5 Sunburst Text to Image	Prompt ≤20000 chars (required)	13 ratios, incl. ultra-wide 21:9 / 27:16 / 16:27 and 9:8 / 8:9	1K / 2K / 4K — resolution is the billing tier	Prompt + resolution + 13 ratios + background (1K only)
2.5 Sunburst Image to Image	Up to 16 image URLs (optional) + prompt ≤20000 chars	Same 13 ratios as Sunburst T2I	1K / 2K / 4K — resolution is the billing tier	Prompt + resolution + 13 ratios + background (1K only) + ≤16 references

v2: "auto" requires 1K and 1:1 does not support 4K. 2.5 Flare / Sunburst: resolution (1K / 2K / 4K) is required and is the billing tier; the ratios 27:16, 16:27, 9:8, 8:9 and the optional background (transparent / opaque / auto) are only supported at 1K. Image inputs: JPEG, PNG, WebP (max 10MB each, up to 16) in the I2I workflows.
