提交后会返回 task_id。如果提供了 callback_url，当任务状态变为 finished 或 failed 时，系统会向 callback_url 发送 POST 请求。
无论是否提供 callback_url，都可以通过统一的查询任务状态接口获取结果。

使用 Seedream 4.5 发展视觉概念，根据一条提示词生成多张图像，探索不同风格和构图。

模型

bytedance/seedream/v4.5/text-to-image - 根据文本提示词生成图像。

功能

根据文本提示词生成图像。
通过 n 控制输出图像数量。

输出选项

图像尺寸

size：可选。默认：1:1。
预设：2K、4K、1:1、4:3、3:4、16:9、9:16、3:2、2:3、21:9。
自定义尺寸时，提供包含整数 width 和 height 的对象，两者都必须为正数。
自定义尺寸也可以使用 WIDTHxHEIGHT 字符串，两个正数之间用 x 或 X 分隔。

图像数量

n：可选。要生成的图像数量。1 到 15 的整数。默认：1。

高级参数

model 和可选的 callback_url 放在请求根级。所有工作流参数（包括输出选项）都放在 input 内。

提示词

prompt：必填。描述期望的图像。长度：1-3,000 个字符。
至少包含一个非空白字符。

安全检查

enable_safety_checker：可选。设为 true 开启内容安全检查，设为 false 关闭。默认：true。
