使用此路由可在 CometAPI 上启动一个 Replicate 风格的 prediction，并返回一个 prediction id 供后续轮询使用。

​
首次请求检查清单

  • 将所有模型参数放在 input 对象内
  • 首次请求建议从 black-forest-labs/flux-schnell 开始，以获得最快的体验
  • 除非你明确需要 input_image 或 input_images，否则首次请求请仅使用文本
  • 保存返回的 prediction id，用于状态检查

​
任务流程

1

创建 prediction

通过此端点提交路径 model ID 和 input 对象。
2

存储 prediction id

保存返回的 id，因为后续轮询需要用到它。
3

轮询 prediction

继续使用 Replicate 查询状态，直到 output 被填充或出现错误。
