Seedream 5
High-fidelity image generation and editing
Generate images from a written prompt or guide the result with a reference image. Run Seedream 5.0 Pro when fidelity matters most, or Seedream 5.0 Lite while you iterate — both available in the imageat image playground and through the API.
Text to image
Turn a written description into a finished image, with prompt adherence tuned for detailed art direction.
Reference-guided editing
Supply an existing image to guide composition, subject, or style instead of starting from a blank prompt.
Pro and Lite
Pick Pro when you want maximum fidelity, or Lite when speed and cost matter more than the last bit of detail.
Request inputs
What you control per request
Start with a prompt, then decide how much guidance the model gets. A reference image constrains composition and subject; the variant, resolution, and aspect ratio decide cost and delivery format.
- Prompt. Describe the subject, setting, lighting, framing, and visual style.
- Reference image. An optional image that guides composition or subject while the prompt drives the rest.
- Variant. Seedream 5.0 Pro for maximum detail, or Seedream 5.0 Lite for faster, cheaper iterations.
- Resolution. Choose the output size that fits your use — Pro tops out at 2K in the imageat playground.
- Aspect ratio. Portrait, landscape, and square ratios for social, web, and print layouts.
FAQ
Seedream 5 questions
What is Seedream 5?
Seedream 5 is ByteDance's image generation model. On imageat it runs in two variants — Pro for maximum fidelity and Lite for faster, lower-cost generation — for both text-to-image and reference-guided editing.
What is the difference between Seedream 5 Pro and Lite?
Pro prioritizes detail and fidelity, while Lite is tuned for speed and cost. Lite is the better choice while you are iterating on a prompt; switch to Pro for the final render.
Can Seedream edit an existing image?
Yes. Provide a reference image alongside your prompt and the model uses it to guide composition, subject, or style rather than generating from scratch.
Do I need a subscription to use Seedream 5?
No. Signup is free and generation runs on pay-per-use credits, so you are only charged for the images you actually generate.
