Cosmonic is demonstrating how WebAssembly could dramatically change the economics of deploying AI agents on Kubernetes. At KubeCon + CloudNativeCon North America 2026, the company showcased a wasmCloud deployment capable of supporting 1.42 million sandboxed environments on a single 64-core server. The demonstration highlights the potential for lightweight WebAssembly isolation to reduce infrastructure overhead as enterprises prepare to deploy large numbers of task-specific AI agents.
