Seedream 4.5: professional AI image generation and editing in one model

Picsart’s AI Image Generator has integrated Seedream 4.5, ByteDance Seed’s newest AI image generation model that unifies image generation and editing into a single workflow. Built for professional creators who need control and consistency, Seedream 4.5 delivers dreamlike visuals, precise text rendering, and character consistency - all at roughly 4x better cost efficiency than competing models.

Seedream 4.5 is ByteDance Seed’s newest AI image generation model. It is a generative image system that unifies image generation and image editing into a single workflow, built for fast iteration and consistency across creative variations. It excels at dense text rendering, character consistency across multiple images, and natural-language image editing with up to 14 reference inputs — making it ideal for professional creators who need control and consistency. For a deeper look at how it stacks up, see our Nano Banana vs Seedream comparison.

Picsart integrates Seedream 4.5 directly into its creative tools, so creators can access its capabilities without interacting with the model itself. It powers Text-to-Image generation, Text-to-Sticker, Logo Generator, and Edit Image with a Prompt. Seedream 4.5 is also available in the AI Playground, where creators can compare results across 132 models with a single prompt.

Seedream 4.5 combines generation and editing in a single model, eliminating the need to switch between separate tools. Its dense text rendering is among the best available — handling headlines, small fonts, and multilingual labels with precision that most competitors cannot match. Character consistency across multiple outputs means campaigns stay visually cohesive. And at approximately $0.04 per image, it delivers roughly 4x better cost efficiency than competing models, making it practical for high-volume professional workflows.

Seedream 4.5 is one of several advanced AI models powering Picsart’s creative ecosystem. It works alongside models from leading AI providers — including Flux 2 Pro, GPT Image 1.5, Ideogram 3.0 Flash, and Nano Banana Pro — to support image generation, editing, and content creation across the platform. This multi-model approach gives creators the flexibility to choose the right model for each project, with Picsart optimizing the experience behind the scenes.
