Typography and graphic design that reads
Seedream 5.0 Pro renders legible headlines, logos, and layout text, so posters, magazine covers, and ads come back print-ready. Dependable text rendering is where it pulls ahead of older image models.
Portraits and characters with reference control
Pass up to ten reference images and the model fuses them into a consistent character or restyled portrait. Multi-reference image-to-image keeps faces and wardrobe on-model across a series.

Why reAPI
Flagship image quality
Seedream 5.0 Pro is ByteDance's top Seedream tier — sharper detail, stronger prompt adherence, and dependable text rendering at up to 2K. It is the model to reach for when the output has to look finished.
Transparent per-image pricing
1 credit equals $0.001. It bills a flat rate per output image by resolution tier — nothing per token, no subscription. Images blocked by moderation are never charged.
Async images API
Submit a prompt to the images endpoint and reAPI returns a task_id. Poll the task until it completes, then read the finished image from output.image_urls. Failed jobs are refunded automatically.
