ByteDance Seed: Seedream 5.0 Lite

Provider-supported parameters

These are upstream capabilities. Jevrouter supports the subset described in the API contract; chat input is currently text only.

Capabilities are imported from OpenRouter’s catalog. This does not mean every model has been independently tested by Jevrouter.

Image prices & options

Prices use each provider’s billing unit. We reserve a conservative amount and settle from the usage receipt, releasing unused balance.
