SDXL 1.0模型开发了使用一个高度优化的培训方法,受益于3.5 billion-parameter基础模型。稳定的人工智能定位作为坚实的基础模型,该公司预计一个生态系统的工具和能力建设。“基础模型是非常有趣的,他们像一个Minecraft释放整个改装社区出现的地方,你看过丰富稳定扩散社区内。但你真的需要有一个坚实的基础的构建,”首席执行官Emad Mostaque稳定AI说。如何稳定扩散的微调已经改良,ControlNet SDXL 1.0 text-to-image代最好的影像的获取通常是一个迭代的过程,和一个SDXL 1.0的目标是简化很多。“微调图像获得的数量急剧下降,“Mostaque说。“现在只有5到10图片一样,你可以很快调整一个了不起的模型。”的一个重要创新,有助于使更容易调整和改进作文SDXL 1.0是一个方法称为“ControlNet。“斯坦福大学研究论文详细今年早些时候这种技术。Mostaque ControlNet可以解释,例如,使输入如骨架图,然后将图像映射到基础扩散噪声基础设施创建一个高精确度和控制。多个参数在SDXL 1.0为什么大不了Mostaque评论说,一个关键的东西帮助启动生成AI的繁荣整体比例,即参数的数量增加导致更多的特性和越来越多的知识。 Mostaque said that the 3.5 billion parameters in the base SDXL 1.0 model leads to more accuracy overall. “You’re teaching the model various things and you’re teaching it more in-depth,” he said. “Parameter count actually matters — the more concepts that it knows, and the deeper it knows them.” While SDXL 1.0 has more parameters, it does not require users to input long tokens or prompts to get the better results, as is often the case with text generation models. Mostaque said that with SDXL 1.0, a user can provide complicated, multi-part instructions, which now require fewer words than prior models, to generate an accurate image. With previous Stable Diffusion models, users needed longer text prompts. “You don’t need to do that with this model, because we did the reinforcement learning with human feedback (RLHF) stage with the community and our partners for the 0.9 release,” he explained. The SDXL 1.0 base model is available today in a variety of locations, including the Amazon Bedrock and Amazon SageMaker Jumpstart services. >>Follow VentureBeat’s ongoing generative AI coverage<< “The base model is open and it’s available to the entire community with a CreativeML ethical use license,” Mostaque said. “Bedrock, Jumpstart and then our own API services, as well as interfaces like Clipdrop that we have, just make it easy to use, because the base model by itself is … a bit complicated to use.” VentureBeat's mission is to be a digital town square for technical decision-makers to gain knowledge about transformative enterprise technology and transact.
