Seedream 5.0 Pro

Seedream 5.0 Pro is an image generation and editing model supporting text-to-image, one to ten reference images, 1K and 2K tiers, and exact output dimensions. It is suited to product visuals, advertising assets, concept design, image editing, and automated creative workflows that need repeatable API access. Use the playground below to test representative prompts, reference images, dimensions, quality settings, output formats, and image counts that are available for this model. Before production rollout, compare visual quality, instruction following, subject consistency, processing time, failure handling, and estimated cost with your actual workload. The controls shown on this page describe the currently supported integration options.

Capabilities

  • Image generation through the current public endpoint
  • Editing or reference-image controls when exposed by the live schema
  • Current parameters including prompt, image, size

Limitations

  • Capabilities and parameter ranges can change; pin and validate the parameter set used in production
  • Do not assume support for parameters absent from the live request schema
  • Asynchronous jobs require explicit polling, failure, timeout, and safety-status handling

Use cases

  • Product prototypes and automated content workflows
  • Batch media generation and programmatic creative tooling
  • Multi-model applications that need unified authentication, billing, and usage records
