Cosmos DB Embeddings Generator Sample
Ever since our first preview announcement for vector indexing and support for DiskANN and then again when we announced the GA for these features, customers have been asking us to make it easier to generate Azure OpenAI embeddings on their data in Azure Cosmos DB. So we did just that and created the Azure Cosmos DB Embeddings Generator sample application and hosted it on GitHub. This sample shows how to use an Azure Cosmos DB Trigger and Output Binding in Azure Functions to automatically generate Azure OpenAI embeddings on a new or updated item, then save it back to the same item in Cosmos DB. There is bo...
An introduction to Multi-Agent AI apps with Azure Cosmos DB and Azure OpenAI
Azure Cosmos DB was named by Bloomberg as the no. 1 Database of choice for Retrieval Augmented Generation (RAG) and Large Language Model (LLM) customization. It is used by OpenAI to scale it’s ChatGPT service, and by many thousands of customers worldwide, serving billions of end-users with globally distributed apps at planet scale. In this blog we will explore a simple example for lightweight multi-agent orchestration in Python using OpenAI Swarm. We’ll also see the benefits of being able to use Azure Cosmos DB as both a vector store and an operational database. What are multi-agent apps? Multi-agent AI apps...
