Seedream 5.0 Lite API Limits: Resolution, Inputs and Request Boundaries

APIMART serves Seedream 5.0 Lite through POST /v1/images/generations. The current documentation describes an asynchronous submit-and-poll workflow. The boundaries below were checked on September 2, 2026.

Verified boundaries

• The endpoint is asynchronous and returns a task_id.
• The current endpoint documentation lists 2K and 3K output tiers, while the product page markets 4K capability; validate the exact route before promising resolution.
• Output format supports JPEG and PNG.
• The current product page describes one to 15 images per request and up to 10 reference images.
• Reference images must stay within documented dimensions and file-size boundaries; the docs list no more than 10MB per image and total pixels no more than 6000 by 6000.
• sequential_image_generation controls grouped output and automatically enables when n is greater than one.

Minimal integration rule

Send the documented model ID, required prompt and only compatible optional inputs. Persist the returned task_id, implement bounded polling and backoff, and keep 400, 401, 402, 429 and 5xx responses out of completed-output metrics.

FAQ

Which endpoint serves Seedream 5.0 Lite?

Use POST /v1/images/generations with the documented model ID and Bearer authentication.

Is processing synchronous?

No. A successful submission returns a task ID that must be polled for completion.

What is the first production safeguard?

Validate model ID, quantity or duration, resolution and input combinations before submission.

Can documented limits change?

Yes. Treat the live endpoint documentation as the source of truth and version your request profile.

Should a submitted task be counted as completed output?

No. Count success only after the task endpoint reports a completed result.
