In this session, we will explore the API Assistants in Azure OpenAI Service. This new feature in Azure OpenAI Service, is now available in public preview. Assistants API represents a new cognitive architecture from OpenAI embedded in a product that makes it simple for developers to create high quality copilot-like experiences within their own applications. Previously, building custom AI assistants needed heavy lifting even for experienced developers. While the chat completions API is lightweight and powerful, it is inherently stateless, which means that developers had to manage conversation state and chat threads, tool integrations, retrieval documents and indexes, and execute code manually. Assistants API, as the stateful evolution of the chat completion API, provides a solution for these challenges.
