Seedream-5-0-260128 API for BytePlus Global Access
Use this route when your documentation, configuration, or logs refer to BytePlus’s shorter global model ID. The sections below identify the endpoint, explain the regional naming difference, and show what must change when moving from a doubao- request.
What Does the seedream-5-0-260128 Model String Mean?
seedream-5-0-260128 is the model ID published in BytePlus ModelArk documentation for Seedream 5.0 Lite. BytePlus also recognizes seedream-5-0-lite-260128 as an alias. The 260128 suffix identifies the January 28, 2026 release; it does not describe image size, quality, or a separate pricing tier.
On GPTProto, the shorter ID has its own text-to-image route because model pages and request paths are generated from the exact model string. Use the ID displayed on this page exactly as written. Adding doubao- inside the URL does not select a higher or lower quality mode—it changes the route to the Volcengine-named version.
Difference Between seedream-5-0-260128 API and Doubao Seedream 5.0 Lite API
| Item | BytePlus / Global Route | Volcengine / Mainland China Route |
| GPTProto model string | seedream-5-0-260128 | doubao-seedream-5-0-260128 |
| Official alias | seedream-5-0-lite-260128 | doubao-seedream-5-0-lite-260128 |
| Naming source | BytePlus ModelArk documentation | Volcengine Ark documentation |
| Underlying release | Seedream 5.0 Lite, dated 260128 | Seedream 5.0 Lite, dated 260128 |
| GPTProto page role | Global model-ID endpoint and migration guidance | Main Lite guide, prompts, use cases, and model comparisons |
The prefix is the only model-name distinction documented for these regional environments. It should not be used to claim different generation quality, reasoning capability, or output style. Upstream base URLs, accounts, authentication, and regional availability can differ when calling BytePlus or Volcengine directly; through GPTProto, follow the route and bearer-key format shown on the selected model page.

The submit call returns a prediction identifier, and the result route is used to retrieve the completed image. Copy the live request from the API tab before deployment, since the displayed schema—not a provider example using another model ID—defines the accepted GPTProto fields.
Migrating from doubao-seedream-5-0-260128
- Change the model slug in the submit URL. Replace doubao-seedream-5-0-260128 with seedream-5-0-260128.
- Keep authentication tied to GPTProto. Continue using the GPTProto bearer key; do not insert a BytePlus or Volcengine key into the GPTProto request.
- Validate the live payload schema. Do not assume every regional provider parameter is exposed by both GPTProto routes. Compare the JSON or API tabs before reusing an existing payload.
- Run a regression set. Test the same prompts, output sizes, error handling, and result polling before changing the route in a customer-facing application.
Do not substitute a 260628 identifier during migration. That suffix belongs to Seedream 5.0 Pro, which is a separate model and price point rather than another alias for this route.
