The Seedream 5 Lite family on WaveSpeedAI ships 4 REST endpoints covering Text-To-Image, Image-To-Image workflows. Each variant carries its own pricing, parameter knobs, and example outputs — pick the one that matches your input modality and production constraints, or call several from the same API key to compose multi-step pipelines.
Run Seedream 5 Lite through the same API key, billing account, and rate-limit envelope you use for the other 1,000+ AI models on WaveSpeedAI. No separate vendor setup, no per-provider SDKs, no per-vendor rate-limit envelopes — one integration covers everything from text-to-image and text-to-video through audio synthesis, 3D generation, upscaling, and editing.

How to use the Seedream 5 Lite API
Four steps from signup to a finished generation. Full Python, Node.js, and cURL examples are in the API section below.
- 1
Get an API key
Sign up for a WaveSpeedAI account and copy your API key from the dashboard. New accounts come with free starter credits — enough to run the playground a few dozen times before billing kicks in.
- 2
Submit a prediction
POST your input as JSON to https://api.wavespeed.ai/api/v3/bytedance/seedream-v5.0-lite. The endpoint returns a prediction id immediately — generations are async so you don't hold an open connection during inference.
- 3
Poll for completion
GET https://api.wavespeed.ai/api/v3/predictions/{request_id}/result every 1-2 seconds. The response includes a status field; keep polling until it flips from"queued" or"processing" to"completed".
- 4
Read the output URL
Once status is"completed", read the URL from data.outputs[0]. The URL points to your generated media on the WaveSpeedAI CDN — image, video, audio, or 3D file depending on the Seedream 5 Lite variant you called.
What you can build with Seedream 5 Lite
Common workflows developers and creators use the Seedream 5 Lite API for.
Cost-optimized 4K image generation
Among the cheapest 4K-capable image models on WaveSpeedAI. Useful for high-volume marketing, social, and editorial pipelines where per-image cost compounds quickly.
Enhanced typography rendering
Same typography focus as Seedream 4.5 — clear text rendering for posters and brand visuals. Useful for marketing creatives where text quality is the limiting factor and per-image cost matters.
Sequential variants for storyboards
bytedance/seedream-v5.0-lite/sequential generates multi-image sets with consistent characters and objects, unifying palette, lighting, and style across all outputs — useful for campaigns and storyboards.
Edit-Sequential for locked identity
bytedance/seedream-v5.0-lite/edit-sequential performs multi-image editing while locking character and object identity across shots. Detects main subjects, preserves continuity, applies controlled edits across the set.
Edit endpoint with reference preservation
bytedance/seedream-v5.0-lite/edit preserves facial features, lighting, and color tones from reference images during prompt-driven edits — high-fidelity professional editing.
Tips for prompting Seedream 5 Lite
Practical advice for getting better outputs from Seedream 5 Lite — drawn from the patterns that work across image models in production pipelines.
Same variant pattern as Seedream 4.5
5 Lite ships base / edit / sequential / edit-sequential — same workflow surface as 4.5. Pick based on availability and any quality differences in your specific prompts.
Use Sequential for storyboards and campaigns
bytedance/seedream-v5.0-lite/sequential generates multi-image sets with consistent characters and objects, unifying palette/lighting/style across outputs. Useful for campaigns, storyboards, and content series.
Edit-Sequential for identity-locked editing
bytedance/seedream-v5.0-lite/edit-sequential performs multi-image editing while detecting main subjects and preserving continuity. Useful for serialized character-driven work and product catalogs.
Typography focus — same lineage as Seedream 4.5
Catalog calls out "enhanced typography, clear text rendering for posters and brand visuals." Useful for text-heavy marketing creatives where Seedream's typography strength matters.
Edit preserves face/lighting/tone from references
bytedance/seedream-v5.0-lite/edit enables high-fidelity editing while preserving facial features, lighting, and color tones from reference images. Useful for portrait refinement and product re-contextualization.
