Systems for AI
Serving AI is expensive. We build systems that reshape how models execute, from adaptive execution to smarter placement, to deliver more useful work from bounded compute, memory, and network capacity.
We research and build the systems infrastructure behind efficient and reliable AI, from serving models on bounded hardware to scaling graph learning and running agents dependably.
NExt-gen X Systems is a research group in the School of Computer Science at Georgia Institute of Technology. The X stands for whatever the next generation of systems is built for. Today, X is AI.
Serving AI is expensive. We build systems that reshape how models execute, from adaptive execution to smarter placement, to deliver more useful work from bounded compute, memory, and network capacity.
AI agents are moving from answering questions to carrying out long tasks. We are building the systems infrastructure necessary for the reliable and efficient operation of agents.
Graph neural networks power recommendation, fraud detection, and drug discovery, but real graphs are large, heterogeneous, and constantly changing. We build systems and models that scale GNN training and serving.
Our research is supported by generous contributions from Adobe, Cisco, Dolby, Google and Zulip.
