Semantic Kernel is an open-source SDK that combines AI services such as OpenAI, Azure OpenAI, and Hugging Face, enabling developers to create AI apps by integrating them with their existing code. It supports Java, Python, and C# and offers connectors for adding memories and AI services to simulate the "brain" of the application. Additionally, AI plugins can be added as the "body" of the app. The SDK simplifies the integration of AI services, allowing developers to leverage recent AI advancements and build intelligent pipelines. This workshop focuses on how to use Semantic Kernel within your existing application and how to build and orchestrate AI applications.
