jimeng-i2v-first-tail

Jimeng first/last-frame video model; constrains shot start/end frames. Good for transitions and clearly resolved action.

Overview

Field	Value
Model ID	`jimeng-i2v-first-tail-v30`
CLI	`dlazy jimeng-i2v-first-tail`
MCP	`jimeng-i2v-first-tail` (Claude Code surfaces this as `mcp__dlazy__jimeng-i2v-first-tail`)
Type	`video`
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
`generation_mode`	"frames"	No	Generation Mode; default `"frames"`
`firstFrame`	url	No	First Frame; image (accepts URL, local path, or data: URL)

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__jimeng-i2v-first-tail; generic clients (e.g. OpenClaw) call it as jimeng-i2v-first-tail.

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.
