IREE (Intermediate Representation Execution Environment, pronounced as "eerie") 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.
See our website for project details, user guides, and instructions on building from source.
- 2025-04-02: AMD submitted an IREE-based SDXL implementation to the MLPerf benchmark suite
- 2024-05-23: IREE joins the LF AI & Data Foundation as a sandbox-stage project
