Overview
Seedream 4.5 is ByteDance's flagship image generation and editing model, and one of the best values in production design. Built by the team behind TikTok's recommendation engine, it specialises in exactly the work agencies do daily: posters, e-commerce key visuals, product detail pages and infographics — anything that needs dense, readable text and on-brand consistency across a set.
Its standout upgrade is typography and dense text rendering, plus multi-image editing that accepts up to 10 reference images and accurately identifies target elements across them. Reviewers call it the best cheap option for design work that has to carry words and stay consistent — a 4K-capable workhorse that beats pricier rivals on cost while matching them on the layouts that matter.
