Seedream 4.5 - Free AI Image Generator

ByteDance's latest photorealistic image model with enhanced detail and composition

Seedream 4.5 is the latest image generation model from ByteDance's Seed Team, leveraging the massive visual training data from TikTok's ecosystem of billions of images and videos. Seedream is the foundation model that powers image generation in Doubao (豆包) and Jimeng (即梦). Seedream 4.5 builds on the 4.0 foundation with significantly improved composition, fine detail rendering, and color accuracy. It offers two quality tiers (2K and 4K) and supports both text-to-image and image-to-image workflows with up to 14 reference images. Unlike FLUX or Imagen which lean toward artistic interpretation, Seedream prioritizes faithful reproduction of real-world textures, lighting, and materials — making it the strongest choice when photorealism is the primary goal. The model also supports seeded generation for reproducible outputs. On Genkee AI, Seedream 4.5 is priced at a flat 2 credits per image regardless of quality tier.
