  • Lots of other features such as in-painting, color sketch, and prompt metric to name a few
  • Thanks to the passionate open-source community, most new features come to this free Stable Diffusion GUI first.

What is Azure?

  • Microsoft Azure, formerly known as Windows Azure, is Microsoft’s public cloud computing platform. It provides a broad range of cloud services, including computing, analytics, storage, and networking. Users can pick and choose from these services to develop and scale new applications or run existing applications in the public cloud.
  • The Azure platform aims to help businesses manage challenges and meet their organizational goals. It offers tools that support all industries — including e-commerce, finance, and a variety of Fortune 500 companies — and is compatible with open-source technologies. This gives users the flexibility to use their preferred tools and technologies. In addition, Azure offers four different forms of cloud computing: infrastructure as a service (IaaS), platform as a service (PaaS), software as a service (SaaS), and serverless functions.

Prerequisites for deploying Stable Diffusion on Microsoft Azure
