Seedream v5.0 Pro Text-to-Image
ByteDance flagship next-generation image generation model with stronger prompt adherence, refined typography, and photorealistic detail. Single-image output at 1.5K and 2K tiers with JPEG and PNG support.
What it does
Seedream v5.0 Pro Text-to-Image, in practice.
Seedream 5.0 Pro is ByteDance's flagship image generation model, unveiled at the Volcano Engine FORCE 2026 conference on June 23, 2026, alongside Seedance 2.5. Positioned above Seedream 5.0 Lite and Seedream 4.5 in the family lineup, the Pro model concentrates the family's advances in prompt adherence, compositional reasoning, and design-grade output quality into a single-image generation engine tuned for professional creative work. Where Seedream 5.0 Lite optimizes for speed and volume, Seedream 5.0 Pro prioritizes per-image quality: stronger interpretation of long, detailed prompts, more faithful spatial logic, and refined typography and layout handling. It generates exactly one carefully
- Flagship Prompt Adherence: Deep multi-step interpretation of detailed prompts — subject relationships, spatial constraints, lighting direction, and stylistic intent are followed with noticeably higher fidelity than earlier Seedream generations.
- Design-Grade Typography & Layout: The Seedream 5.0 family leads its class in structured visual design — accurate CJK text rendering, clean UI mock-ups, and coherent infographic layouts, the one category where it decisively beat Google's Nano Banana 2 in independent head-to-head testing.
- Two Quality-Matched Output Tiers: A fast, economical 1.5K tier (up to ~2.36M pixels, e.g. 1536×1536, 2048×1152) and a premium 2K tier (up to 2048×2048 total pixels, with 16:9 output reaching 2848×1600 ≈ 2.8K in resolution-keyword mode) let you match resolution to use case within one model.
- Flexible Aspect Ratios: Any aspect ratio from 1:16 to 16:1 across both tiers, with preset sizes covering square, 4:3, 3:4, 16:9, and 9:16 compositions.
- Automatic Prompt Optimization: A built-in `standard` prompt-optimization mode rewrites terse prompts into fully specified generation instructions for higher-quality output without prompt-engineering effort.
- Single-Image Discipline: Always returns exactly one image per request — no group/sequential fan-out — keeping cost per usable asset predictable for production pipelines.

Parameters
What you can set.
| Parameter | What it does | Options |
|---|---|---|
prompt | The positive prompt for the generation. Recommended length: under 600 English words. | |
size | Output image size in 'WIDTH*HEIGHT' pixels. Total pixels must stay within [1,048,576 (1024*1024), 4,194,304 (2048*2048)] and aspect ratio within [1/16, 16]. Billing tier is by total output pixel count: <= 2.36M px bills at the 1.5K tier; la | 2048*2048 2304*1728 1728*2304 2720*1530 1530*2720 2496*1664 1664*2496 1024*1024 1536*1536 1776*1328 1328*1776 2048*1152 |
output_format | Output image file format. Seedream v5.0 Pro supports both JPEG and PNG output. | jpeg png |
thinking | Controls the deep-thinking phase of automatic prompt optimization. Set to 'disabled' to skip prompt-optimization thinking for faster generation (text-to-image completes significantly faster; editing latency is largely unaffected). | enabled disabled |
prompt_optimization_mode | Prompt optimization mode. 'standard' (default) produces higher-quality prompt optimization but takes longer. 'fast' takes significantly less time with slightly lower quality. Billing is identical in both modes. For the fastest generation se | standard fast |
