FLUX文生图模型
支持的领域 / 任务:aigc
FLUX模型是由 Black Forest Labs 开源的高质量文本到图像生成模型,它在多个维度上展现了卓越性能,尤其在文本引导的图像生成、多主体场景构建、以及精细的手部细节生成等方面,实现了显著的提升,为文生图领域设定了新的技术标杆。
上线的 FLUX.1 [schnell] 模型作为目前开源最先进的少步模型,不仅超越了同类竞争者,甚至还优于诸如 Midjourney v6.0 和 DALL·E 3 (HD) 等强大的非精馏模型。该模型经过专门微调,以保留预训练阶段的全部输出多样性,相较于当前市场上的最先进开源模型, FLUX.1 [schnell] 显著提升了在视觉质量、指令遵从、尺寸/比例变化、字体处理及输出多样性等方面的可能,为用户带来更为丰富多样的创意图像生成体验。
同时上线的 FLUX.1 [dev] 模型是一款面向非商业应用的开源权重、精炼模型。 FLUX.1 [dev] 在保持了与 FLUX 专业版相近的图像质量和指令遵循能力的同时,具备更高的运行效率。相较于同尺寸的标准模型,它在资源利用上更为高效。
除了为 FLUX 系列的官方模型与基于 FLUX 架构的开源社区模型提供服务化支撑外,我们还针对 FLUX 文生图模型实施了中文 Prompt 的适应性优化。此番调整确保了模型能够深刻理解并精准响应中文指令,进而生成与英文 Prompt 同等质量的图像成果。
快速开始
前提条件
已开通服务并获得api-key:API-KEY的获取与配置。
已安装SDK:安装DashScope SDK。
示例代码
以下示例展示了调用 flux-schnell 模型API进行文生图的快速示例代码。以下示例展示了调用 flux-schnell 模型API进行文生图的快速示例代码。如果要调用 flux-dev 模型,只需要修改 model 为 "flux-dev" 即可。
需要使用您的api-key替换示例中的 your-dashscope-api-key ,代码才能正常运行。
