+              OpenXLA Project develops StableHLO, a portable ML compute
+              operation set that makes frameworks easier to deploy across
+              different hardware. WebNN API targets diverse hardware platforms
+              and defines an operation set whose high-level operations can be
+              decomposed to low level primitives that can map to StableHLO
+              operations. Coordination and alignment between these two
+              operation sets is beneficial to the open ML ecosystem.
