IREE (Intermediate Representation Execution Environment) is an MLIR-based end-to-end compiler and runtime that lowers Machine Learning (ML) models to a unified IR that scales up to meet the needs of the datacenter and down to satisfy the constraints and special considerations of mobile and edge deployments.

IREE is a sandbox-stage project of LF AI & Data Foundation. IREE was donated to LF AI & Data Foundation by Google and AMD in May 2024.
