Seedream v5.0 Lite
Seedream v5.0 Lite brings the Seedream 5.0 image workflow to faster everyday creation and editing. It is intended for prompt-led visual production where clear composition, usable text, and dependable instruction following matter, without requiring the heavier Pro route for every iteration.
The Lite route is well suited to concept exploration, campaign variants, social assets, and practical image revisions. It generates a fresh image from a written brief and offers direct canvas and output-format controls.
Highlights
- Fast creative iteration. Supports rapid exploration of visual directions before a team commits to final production.
- Instruction-led composition. Uses the prompt to coordinate subject, setting, style, layout, and requested textual elements.
- Practical design output. Targets clear, usable images for marketing, editorial, social, and concept-development workflows.
- Flexible canvas delivery. Offers multiple aspect ratios and common image encodings for different placements.
Pricing
| Configuration | Billing unit | Price |
|---|---|---|
| Base generation | Per request | $0.035 |
When to Use
| ✅ Good fit | ❌ Consider alternatives |
|---|---|
| The project needs creating a prompt-led image | The goal is a different media task or endpoint |
| The available inputs match the required local schema | Required source media or permissions are unavailable |
| The brief can specify subject, composition, style, and delivery | The result must be deterministic at pixel or sample level |
| The supported formats and controls match final placement | Delivery requires unsupported dimensions, codecs, or duration |
| An asynchronous generated result fits the workflow | A live, frame-synchronous, or real-time response is mandatory |
Prompt Guide
Write the request as a production brief: identify the main subject or source material, state the intended transformation, describe composition or timing, and finish with style, atmosphere, and delivery constraints. Keep preservation requirements separate from requested changes, and use only fields exposed by this route.
