seedream-4.5

High-quality text-to-image/image-to-image model, suitable for posters, realism, and creative scenes. Supports prompt + multiple reference images, outputting single high-res images (2K/4K).

Overview

Field	Value
Model ID	`doubao-seedream-4-5`
CLI	`dlazy seedream-4.5`
MCP	`seedream-4.5` (Claude Code surfaces this as `mcp__dlazy__seedream-4.5`)
Type	`image`
Execution	Async task; the CLI polls until completion (`--no-wait` returns `generateId` immediately)
Batch	Supports `--batch <n>` parallel fan-out

Parameters

Arg	Type	Required	Notes
`prompt`	string	Yes	Prompt
`images`	array<url>	No	Images; image (accepts URL, local path, or data: URL); max 10 items
`resolution`	"2k" \| "4k"	No	Resolution; default `"2k"`

MCP is consumed by AI clients, not handwritten. Once dLazy is registered as an MCP server the tool appears in the client's tool list — Claude Code surfaces it as mcp__dlazy__seedream-4.5; generic clients (e.g. OpenClaw) call it as seedream-4.5.

See MCP setup for how to add the server.

Media tools emit image / video / audio / file outputs. Use --output url to print only the URLs on stdout.
