}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 以供后续轮询。
首次请求检查清单
- 将所有模型参数都放在
input对象内 - 使用
black-forest-labs/flux-schnell作为最轻量的冒烟测试起点 - 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
轮询 prediction
继续参考 Replicate 查询状态，直到
output 被填充或出现错误。2026-03-12 的实时验证确认，
black-forest-labs/flux-schnell 接受了纯文本请求，并返回了一个状态为 starting 的 prediction id。授权
Bearer token authentication. Use your CometAPI key.
路径参数
Replicate model id, for example black-forest-labs/flux-schnell or black-forest-labs/flux-kontext-pro.
请求体
application/json
Provider-specific model input. Keep all parameters inside this object.
