Vortex: Efficient and Programmable Sparse Attention Serving for AI Agents
arXiv 2606.06453·high signal
Vortex is a serving system that makes sparse attention programmable and efficient for long-generation LLM agent workloads, where generation lengths keep growing and dense attention becomes a bottleneck. It targets the practical inference-cost problem builders hit when deploying agents that produce very long outputs. Directly actionable for anyone serving agentic LLMs at scale.
