Midjourney 通过统一异步任务接口 /v1/tasks 调用,用 action 字段区分操作,一个 model 暴露全部能力。 两类操作:

独立生成类 — 不依赖前序任务:imagine(文生图)、blend(多图融合)、describe(图转文)、edits(全图重写)
链式操作类 — 基于前一个任务的产物再加工,需传 ref_task_id 引用前序任务:upscale(放大)、variation / high-variation / low-variation(变体)、reroll(重出网格)、zoom(外绘缩放)、pan(方向平移)、remix-strong / remix-subtle(v8 重塑)

imagine 等生成类返回 2×2 四宫格(一张图含 4 个画面)。要对其中某一张放大 / 变体,用链式操作传 ref_task_id(该网格任务的 task_id)+ index(1-4 选第几张)。详见链式操作。

定价

按操作 + 速度档计费(单位 USD)。speed 取 relax(默认) / fast / turbo。

操作	relax / 默认	fast	turbo
`imagine`	`$0.05067`	`$0.06192`	`$0.1125`
其余全部 action	`$0.06192`	`$0.06192`	`$0.1125`

任务失败自动全额退款。

Action 速查

action	类型	必填	说明
`imagine`	生成	`prompt`	文生图;可加 `image_urls` 做图像引导。出四宫格
`blend`	生成	`image_urls`(2-4)	多图融合,无 prompt
`describe`	生成	`image_urls`(1)	图转文,返回 4 条提示词建议
`edits`	生成	`prompt` + `image_urls`(1)	全图重写(背景替换 / 风格迁移)
`upscale`	链式	`ref_task_id` + `index`	放大网格中第 `index` 张
`variation`	链式	`ref_task_id` + `index`	基于某张出新的四宫格变体
`high-variation`	链式	`ref_task_id` + `index`	强变体(变化幅度大)
`low-variation`	链式	`ref_task_id` + `index`	弱变体(保持主体)
`reroll`	链式	`ref_task_id`	用同 prompt 重出一组四宫格
`zoom`	链式	`ref_task_id` + `zoom_ratio`	外绘缩放(`<2` 用 1.5x,`≥2` 用 2x)
`pan`	链式	`ref_task_id` + `direction`	向 `left/right/up/down` 平移外绘
`remix-strong`	链式	`ref_task_id` + `index`	v8/v8.1 大幅重塑,可改 prompt
`remix-subtle`	链式	`ref_task_id` + `index`	v8/v8.1 保守重塑

可用模型

模型 ID	说明
`midjourney`	Midjourney 全功能,15 种 action(生成 + 链式),支持 v5.1–v8.1 / niji

链式操作

链式 action 基于前一个任务的产物再加工,核心是 ref_task_id 和 index。

先生成网格

调 imagine 拿到响应里的 task_id(例如 task-wave1781770984b950327128),它对应一张 2×2 四宫格。

引用网格 + 选图

链式操作传 ref_task_id(= 上一步的 task_id)+ index(1-4,左上=1 右上=2 左下=3 右下=4)。例如 upscale 放大第 2 张。

继续链式

放大后的单图任务又可作为 zoom / pan 的 ref_task_id,层层叠加。

ref_task_id 必须是你自己、已成功、同一渠道的任务,否则报错(source_task_not_found / source_task_not_owned / source_task_not_success / source_task_channel_mismatch)。引用的是任务 task_id,不是结果图片 URL。

各链式 action 对来源任务的要求:

action	来源任务	选图
`upscale` / `variation`	imagine / reroll 的四宫格	`index` 必填
`high-variation` / `low-variation`	upscale 后的单图	`index` 必填
`reroll`	imagine 的四宫格	不需 index
`zoom` / `pan`	upscale 后的单图	不需 index
`remix-strong` / `remix-subtle`	v8/v8.1 的 imagine 四宫格	`index` 必填
