We’re excited to bring ByteDance Seedream 4.5 to Pixazo — a powerful new generation of image creation and editing designed for professional-quality visuals with high consistency and exceptional fidelity. Seedream 4.5 API is now live in the Pixazo AI Playground (Beta) for hands-on creation, and available via Pixazo API for developers who want to ship it in production workflows.

Seedream 4.5 is a meaningful upgrade for anyone building real creative outputs — especially where style precision, reference locking, and typography matter. It improves subject identification in multi-image edits, preserves reference details more strictly, and noticeably enhances text rendering for posters and branded creatives.

Why Seedream 4.5 stands out?

Seedream 4.5 is built for the creative tasks that most image models still struggle with — especially reference fidelity, multi-image editing reliability, and text rendering.

1) Better reference locking & multi-image editing

Seedream 4.5 more accurately identifies the main subject when multiple references are involved, and it preserves details from those references more strictly. That translates to higher consistency across edits and iterations, especially for product shots, characters, and branded assets.

2) Professional typography & dense text rendering

Posters, social ads, labels, and brand creatives often fail because AI text turns to mush. Seedream 4.5 specifically improves typography and dense text rendering, making it far more reliable for design-forward marketing outputs.

3) Higher fidelity and predictable aesthetics

Through overall scaling, Seedream 4.5 delivers sharper visuals, stronger compositional stability, and more dependable instruction following — so what you ask for is closer to what you get.
