Summary:

• **What is Azure Cosmos DB?** Azure Cosmos DB is a powerful database that stores and manages large amounts of information very quickly. In this article, Microsoft shows how developers can use it with special AI tools to create smart applications that can think and learn, making apps more helpful and intelligent.

• **Working Together with AI Tools** Microsoft's Azure Cosmos DB works together with Vercel's AI SDK (a set of tools for building artificial intelligence) to make it easier for programmers to build apps that use AI. When these tools work together, developers can create applications faster and more efficiently, kind of like having a helpful assistant while building something new.
