A detailed explainer on MLIR argues that it has become a unifying layer across modern AI and accelerator compilers.

• The post explains what MLIR is, what it is not, and why it matters.
• It traces how stacks such as XLA, Triton, Mojo, Torch-MLIR, IREE, and ONNX-MLIR all connect through MLIR.
• The key idea is the dialect system: tensor operations are progressively lowered toward machine code through a shared compiler infrastructure.
• The article also clarifies what MLIR does and does not provide, and why its seams matter for how modern compilers are built.
