Flux 生成图像 - CometAPI Documentation

curl --request POST \ --url https://api.cometapi.com/flux/v1/{model} \ --header 'Authorization: Bearer <token>' \ --header 'Content-Type: application/json' \ --data ' { "prompt": "Hello" } '

概述

/flux/v1/\{model\} 端点使用 Black Forest Labs 的 Flux 模型系列根据文本 Prompt 生成高质量图像。只需替换 URL 路径中的 model ID，即可在不同的 Flux 变体之间切换。

由于 Flux 系列模型之间的参数列表差异较大，请参阅官方文档了解详细使用说明。此处提供的参数列表仅供参考。生成完成后，使用 /flux/v1/get_result 端点查询已生成的图像或监控处理状态。BFL 服务返回的图像 URL 大约会在 10 分钟 后过期。请及时保存生成结果。
