Seedream 5.0 Pro Text-to-Image Spicy API

Seedream 5.0 Pro is ByteDance's Seed research team's flagship image generation model released on July 8, 2026. This document covers its Text-to-Image Spicy endpoint: generating high-quality images from natural-language prompts, with native 2K output, layer separation, 14-language text rendering, and precision editing. Spicy mode is the uncensored variant of Seedream 5.0 Pro — it removes standard content restrictions while preserving the same generation capabilities, offering greater creative freedom.

On iCreat, developers call the seedream-5.0-pro/text-to-image endpoint through an asynchronous task-based REST API. Pricing: 2K tier at $0.09/image.

Model Positioning

Seedream 5.0 Pro Text-to-Image Spicy targets uncensored text-to-image generation — the Spicy endpoint of Seedream 5.0 Pro. Compared to the standard version, Spicy removes content moderation filters while maintaining the same generation quality, making it suitable for advertising, art, and concept design that demand freer creative expression. Native 2K resolution output at ~2.1 seconds/image, priced at about one-quarter of GPT Image 2.

Core Capabilities

2K native output

Supports 7 sizes in the 2K tier (square, landscape, portrait), with native resolution output — not upscaled.

Layer separation

Outputs 10+ independent transparent PNG layers (text, subjects, backgrounds, decorative elements separated). Downstream designers can edit individual elements without regenerating the full image. The model automatically inpaints background areas obscured by subjects.

14-language text rendering

Natively supports text rendering in 14 languages including Chinese, English, Japanese, Korean, Thai, Russian, Spanish, French, German, and Arabic (RTL), with ~89.5% typography accuracy.

Complex information visualization

Excels at infographics, data charts, flowcharts, and other structured visual content — ideal for education, business reports, and editorial layouts.

Photorealistic portraits and materials

Micro-detail skin texture rendering (sweat, stray hairs, realistic light behavior), following real lighting logic and shallow depth-of-field control for editorial-grade portrait photography.

Precision editing

Supports four editing modes — point selection, lasso, box, and sketch — plus color replacement and material swap, enabling local modifications without regenerating the entire image.

Fast generation

~2.1 seconds/image (Atlas Cloud benchmark), approximately 2× the speed of GPT Image 2.

Pricing

2K tier supported sizes: 2048x2048, 2304x1728, 1728x2304, 2496x1664, 1664x2496, 2720x1530, 1530x2720

Billed per generated image at $0.09 each.

Use Cases

• Advertising and marketing: posters, infographics, brand visuals — text and graphics in one pass
• E-commerce product display: product images, scene imagery, multi-size adaptation
• Editorial portrait photography: realistic portraits, fashion shots, magazine covers
• Education and information visualization: data charts, flowcharts, multi-panel explanations
• Concept design and art: freer creative expression under uncensored mode
• Multilingual layouts: 14-language text rendering for global market assets

Specifications

Architecture

Seedream 5.0 Pro T2I Spicy uses an asynchronous task-queue architecture. Requests enter the task queue via the submit endpoint and are processed by the Seedream 5.0 Pro generation system. The model performs a reasoning pass before generation (layout, text content, object relationships), then executes image generation. Spicy mode removes the standard version's content moderation filter at the review layer, preserving the same generation backbone and reasoning capabilities. The system supports multi-layer separation output — rendering text, subjects, backgrounds, and decorative elements as independent transparent PNG layers, with automatic inpainting of background areas obscured by subjects. Inference speed is ~2.1 seconds/image, supporting batch task queues.

Notes

• size must be one of the 7 supported 2K-tier sizes; 1K and other sizes are not supported
• prompt max length 32,000 characters; exact text should be in quotes to improve rendering accuracy
• Text accuracy is ~89.5%; complex long strings may still fail — manually verify important text, logos, and packaging details before publishing
• Spicy mode is uncensored; generated content is not subject to the standard version's content restrictions — comply with local laws and regulations when using
• Layer separation output is optional; standard text-to-image requests return a single merged image
• Reference images (up to 10) are optional, for style or content consistency guidance
• Fetch results via the result endpoint promptly after completion

FAQ

What is the difference between Spicy and the standard version?

Spicy is the uncensored variant of Seedream 5.0 Pro, removing the standard version's content moderation filter while maintaining the same generation capability and quality — suitable for advertising, art, and concept design that require freer creative expression. Both share the same price, resolution, and features.

What output sizes are supported?

7 sizes in the 2K tier: 2048x2048 (square), 2304x1728 / 2496x1664 / 2720x1530 (landscape), 1728x2304 / 1664x2496 / 1530x2720 (portrait).

Is text rendering accurate?

14-language text rendering accuracy is ~89.5%. Logos, labels, and short headlines usually pass; multi-paragraph small-size body text may error — manual review is recommended before publishing.

Can it output layered files?

Yes. Seedream 5.0 Pro supports multi-layer separation — 10+ independent transparent PNG layers (text, subjects, background, decorations) that designers can edit individually. Standard text-to-image requests return a single merged image.

What is the difference from Seedream 5.0 Lite?

Pro is the flagship production model (2K, layer separation, 14 languages, precision editing, $0.09/image); Lite is the lightweight batch model (2K/3K, 1–4 images/request, $0.031/image) for low-cost batch generation. Choose Pro Spicy for production-grade assets, Lite for batch volume.

How is billing calculated?

Billed per generated image: 2K tier at $0.09/image. The first reference image is free; each additional reference is ~$0.003 (subject to platform).
