Doubao-Seedream-5.0-Lite Doubao-Seedream-5.0-lite是字节跳动发布的最新图像创作模型。该模型首次搭载联网检索功能，能融合实时网络信息，提升生图时效性。同时，模型的聪明度进一步升级，能够精准解析复杂指令和视觉内容。此外，模型在世界知识广度、参考一致性及专业场景生成质量上均有增强，可更好地满足企业级视觉创作需求。 * 模型ID：`doubao-seedream-5.0-lite` * 模型价格：你可以在[模型广场](https://geekai.co/models?platform=bytedance\&type=image)查看最新价格信息 * 调用入口：`https://geekai.co/api/v1/images/generations` * 模型参数：参考[画图 API 手册](https://docs.geekai.co/cn/api/image/generations) * API认证：[获取 API KEY](https://docs.geekai.co/cn/docs/quick_start) 不支持画图 API 中的以下参数： * `negative_prompt` * `strength` * `aspect_ratio` * `quality` * `n` * `style_preset` * `mask` * `background` 附：[Seedream 5.0 官方 API 文档](https://www.volcengine.com/docs/82379/1824121) Doubao-Seedream-5.0-Lite 不支持设置图片宽高比及分辨率,可以通过 `size` 字段实现，该字段支持两种方式传值： * 指定生成图像的分辨率: `2K`、`3K`、`4K`, 并在 `prompt` 中用自然语言描述图片宽高比、图片形状或图片用途，最终由模型判断生成图片的大小。 * 指定生成图像的宽高像素值，默认值是 `2048x2048`，对应宽高比为 1:1，此外还可以通过如下像素值生成不同宽高比的图片： | 分辨率 | 宽高比 | 像素值 | | --- | ---- | --------- | | 2K | 1:1 | 2048x2048 | | | 4:3 | 2304x1728 | | | 3:4 | 1728x2304 | | | 16:9 | 2848x1600 | | | 9:16 | 1600x2848 | | | 3:2 | 2496x1664 | | | 2:3 | 1664x2496 | | | 21:9 | 3136x1344 | | 3K | 1:1 | 3072x3072 | | | 4:3 | 3456x2592 | | | 3:4 | 2592x3456 | | | 16:9 | 4096x2304 | | | 9:16 | 2304x4096 | | | 3:2 | 3744x2496 | | | 2:3 | 2496x3744 | | | 21:9 | 4704x2016 | | 4K | 1:1 | 4096x4096 | | | 4:3 | 3520x4704 | | | 3:4 | 4704x3520 | | | 16:9 | 5504x3040 | | | 9:16 | 3040x5504 | | | 3:2 | 3328x4992 | | | 2:3 | 4992x3328 | | | 21:9 | 6240x2656 | ### 文生图 通过给模型提供清晰准确的文字指令，即可快速获得符合描述的高质量单张图片： ```bash theme={null} curl --location --request POST 'https://geekai.co/api/v1/images/generations' \ --header 'Content-Type: application/json' \ --header 'Authorization: Bearer $GEEKAI_API_KEY' \ --data '{
