API de Seedream
ByteDance's Seedream image line, with prompt-optimisation modes and JPEG or PNG output.

modelos en la línea
Seedream is ByteDance's image generation and editing line. All three tiers we serve share the same ten framing options — including an adaptive mode that lets the model choose — a choice of JPEG or PNG output, and a prompt-optimisation switch that decides whether the model rewrites your prompt before generating. Prices sit close together, so the decision is about resolution ceiling rather than budget.

Cuál elegir
Seedream 5.0 Lite
The cheapest tier, and the only one that reaches 3K as well as 2K and 4K.
Seedream 4.5
The previous generation, at 2K or 4K, when you want its rendering rather than 5.0's.
Seedream 5.0 Pro
Quality-focused work at 1K or 2K, with reference images billed separately and cheaply.
Puntos fuertes
- Prompt-optimisation mode is exposed as a parameter, so you can turn the model's own prompt rewriting off when you want literal control.
- Output format is selectable — PNG when you need lossless, JPEG when you need small.
- An adaptive aspect ratio that lets the model pick the framing for the subject.
- On 5.0 Pro, reference images are billed at a fraction of a generation.
Limitaciones
- 5.0 Pro tops out at 2K, so the highest resolutions come from the older 4.5 or from Lite.
- Resolution ceilings differ per tier (1K/2K, 2K/4K, 2K/3K/4K), which makes swapping tiers less transparent than it looks.
- Prices are close together, so there is no genuinely cheap tier for volume drafting.
