如何以规模化方式使AI生成的图像栩栩如生

We launched Meta AI with the goal of giving people new ways to be more productive and unlock their creativity with generative AI (GenAI). But GenAI also comes with challenges of scale. As we deploy new GenAI technologies at Meta, we also focus on delivering these services to people as quickly and efficiently as possible.

我们推出了Meta AI，旨在为人们提供更多生产力和解锁创造力的方式，通过生成式人工智能（GenAI）。但是，GenAI 也带来了规模方面的挑战。在部署 Meta 的新 GenAI 技术时，我们还专注于以尽快和高效的方式向用户提供这些服务。

Meta AI’s animate feature, which lets people generate a short animation of a generated image, carried unique challenges in this regard. To deploy and run at scale, our model to generate image animations had to be able to serve billions of people who use our products and services, do so quickly – with fast generation times and minimal errors, and remain resource efficient.

Meta AI的动画功能使人们能够生成生成图像的短动画，在这方面带来了独特的挑战。为了能够大规模部署和运行，我们用于生成图像动画的模型必须能够为数十亿使用我们产品和服务的用户提供服务，快速生成时间和最小错误，并保持资源高效。

Here’s how we were able to deploy Meta AI’s animate feature using a combination of latency optimizations, traffic management, and other novel techniques.

以下是我们如何使用延迟优化、流量管理和其他新颖技术来部署 Meta AI 的动画功能。

Optimizing latency for generating image animations

优化生成图像动画的延迟

Before launching the animate feature across our family of apps and on the Meta AI website, making animation models fast was one of our top priorities. We wanted people to see the magic of requesting an animation and seeing it appear in just a few seconds. Not only was this important from a user perspective, but the faster and more efficient we made our model, the more we could do with fewer GPUs, helping us scale in a sustainable way. Our work in creating animated stickers with video diffusion, accelerating image generation with Imagine Flash, and accelerating diffusion models through block caching all helped us develop novel techniques we used to accomplish large latency wins.

在将动画功能推出到我们的应用程序系列和Meta AI网站之前，使动画模型变快是我们的首要任务之一。我们希望人们能够看到请求动画并在几秒钟内看到它出现的魔力。这不仅对用户来说很重要，而且我们使模型变得更快、更高效，我们就可以用更少的GPU做更多的事情，以可持续的方式扩展。我们在使用视频扩散创建动画贴纸，使用Imagine Flash加速图像...
