Start with Seedream 4.5

Dense Text & Typography

Seedream 4.5 is tuned for legible, dense text inside images—headlines on posters, labels on packaging, UI mockups, and editorial layouts where most AI models produce garbled letterforms. ByteDance's research highlights improved typographic rendering across complex layouts, making Seedream 4.5 a practical choice for marketing drafts, social creatives, and design exploration that must include readable copy.

2K & 4K Quality on PixPal

On PixPal, choose 2K for balanced speed and detail or 4K when you need sharper final assets for large displays, print-adjacent workflows, or premium marketing deliverables. Combined with aspect ratios from 1:1 squares to 21:9 cinematic widescreen, Seedream 4.5 covers social feeds, vertical video frames, presentation slides, and hero banners in one generator.

Up to 14 Reference Images

Upload up to 14 reference images per request for image-to-image workflows on PixPal. Seedream 4.5 identifies main subjects across references, preserves identity-relevant details, and composes coherent outputs—ideal for character continuity, product variants, style-matched campaigns, and multi-asset brand systems.

Unified Generation & Editing

Text-to-image and image editing run on one model architecture. Start from a prompt to explore directions, then upload source or reference images to refine backgrounds, adjust styling, or maintain subject fidelity across a series—without leaving the Seedream 4.5 workflow on PixPal.

Introduce

What is Seedream 4.5

Seedream 4.5 is ByteDance's upgraded image generation model, released in late 2025 on Volcengine and integrated into the Doubao and Jimeng ecosystem. Built as an all-round improvement over Seedream 4.0, it scales model capacity to deliver sharper prompt adherence, stronger editing consistency, and markedly better dense-text rendering for posters, packaging, and visual design layouts. On PixPal, Seedream 4.5 is available for text-to-image and image-to-image workflows with up to 14 reference images per request, 2K or 4K quality tiers, ten aspect ratio presets plus Auto framing in image-to-image mode, and batch output from 1 to 15 images. The same architecture handles both generation and editing—so you can create a base visual and refine it without switching models. If you need reasoning layers, live web search grounding, or conversational multi-turn editing, see Seedream 5.0 on PixPal; choose Seedream 4.5 when dense typography, multi-reference composition, and fast production output are your priority.
