Show HN: Seedream 4.5 – High-Consistency AI Image Generation for Creators
Hi HN,

we’ve been working on Seedream 4.5, a next-generation image model focused on high consistency, realistic detail, and multi-image creative control. It’s designed for creators who need stable characters, clean structure, and production-grade visuals — not just lucky one-off generations.

Key features:

Multi-Image Consistency: Maintain the same face, style, lighting, and scene logic across batches or sequential renders.

High-Fidelity Rendering: Improved materials, shadows, anatomy handling, and fine-detail realism.

Flexible Workflows: Supports text-to-image, reference-to-image, multi-reference fusion, style transfer, layout-aware generation, and high-res outputs.

Creator-Ready Editing: Modify backgrounds, clothing, mood, and composition while preserving identity and structure.

Fast Iteration: Generate multiple variations, refine style, or re-render consistent character sets in seconds.

Why we built this:

Seedream 4.5 aims to make coherent, editable, production-oriented image generation accessible to artists, designers, marketers, and anyone building multi-shot or multi-style visual workflows.

We’d love feedback on:

How you’d use high-consistency image models in your projects.

What tools or APIs would make Seedream easier to integrate.
