Seedream 4.5 — ByteDance's Flagship Multi-Reference AI Image Generator
Seedream 4.5 is ByteDance's top-tier image model — the strongest prompt adherence in the family, multi-reference composition with up to 10 inputs, and a wide style range from photoreal to illustration. The model creators reach for when one prompt has to honor several references at once.
Qu'est-ce que Seedream 4.5 ?
Seedream 4.5 is the flagship of ByteDance's Seedream family — the direct successor to Seedream 4.0 (which stays available at /models/seedream-4 for its broader size range and advanced editing behavior). 4.5 raises the bar on prompt adherence and multi-reference composition: up to 10 inputs blended coherently in a single generation, with named subjects that stay consistent across variants.
On animx you use Seedream 4.5 alongside Nano Banana, Flux, GPT Image 2, and the rest of the top image models in the same workspace. Bundled with every top video model on a single subscription — hand off any Seedream 4.5 image directly to Veo, Kling, or Seedance for image-to-video without re-uploading.
Ce qui rend Seedream 4.5 différent
Top-tier prompt adherence
4.5 improves on 4.0's already-strong prompt following. Long, structured prompts hold together — spatial relationships, named characters, prop positions, and style cues all land instead of drifting between regenerations.
Multi-reference composition
Up to 10 input images per generation, blended coherently. Subject reference, style reference, setting reference, prop reference — Seedream 4.5 composes them into a single scene where each source's intent shows through.
Wide style range
One prompt photoreal, the next stylized illustration, the next anime-adjacent. Style cues in the prompt actually steer the output instead of producing the same generic look.

Pour qui Seedream 4.5 est conçu
From reference-driven editors to brand teams composing variants to concept artists working from mood boards — Seedream 4.5 fits any workflow where the brief comes with visual material.
Reference-driven editors
Work where the brief arrives with sample images — match this character, in this style, with this setting. Seedream 4.5's multi-input composition is purpose-built for the workflow.
Brand teams building variant sets
One brief, many variants — same character, different backgrounds; same product, different lighting. Seedream 4.5's reference-driven composition turns "keep this consistent, change only that" into a single prompt instead of a regenerate-until-it-matches loop.
Concept artists composing scenes
Story panels, character sheets, lookbook variants where each frame needs to land specific elements. Pull in a subject reference, a style reference, and a setting reference — Seedream 4.5 composes the scene.
