Real-world Applications of Gen AI and Databases

Speaker:

Sailesh Krishnamurthy

System: 

AlloyDB

In this talk we will explore the transformative potential of integrating databases and generative AI in enterprise applications. As Large Language Models (LLMs) are being rapidly adopted, it's clear that they need to interact with a plethora of other systems in the enterprise and agentic applications have emerged as the primary integration mechanism. Of these integration targets, databases are critical,... Read More
