A programming language for all AI developers

Modular's Python-superset combining Python ergonomics with systems-level performance: fully open source since 2025.

Modular's language by Chris Lattner (Swift, LLVM): Python's syntax and ecosystem compatibility with systems-level speed via MLIR compilation. Open sourced fully in 2025, it targets AI kernels and performance-critical Python replacement.

Who it's for

AI engineers who want Python syntax with systems-level performance for ML workloads.
