Mojo 1.0 Beta
Modular’s Mojo hits 1.0 beta: a compiled, statically-typed language blending Python syntax with Rust-style memory safety and unified CPU/GPU kernel programming.
What Matters
- GPU and CPU code runs in the same language with no vendor-specific libraries and no separately-compiled kernels.
- Python interop works via direct import in both directions; SIMD-vectorized Mojo functions callable from existing Python code.
- Compile-time metaprogramming uses runtime Mojo syntax, enabling hardware-specific conditional compilation at zero runtime cost.
- Roadmap: Phase 1 (current) targets CPU/GPU kernels; Phase 2 adds guaranteed memory safety; Phase 3 adds Python dynamic class compatibility.
- Compiler open-source planned for 2026; standard library already on GitHub.

[HN: @ainch] Basic string indexing
var x = 'hello'; x[3]failed in testing, signaling Python dev ergonomics aren’t there yet. - [HN: @fibonacci112358] Nvidia’s CuTile for Python (CUDA Tile IR, MLIR-based) is a direct competing path, heavily integrated into existing CUDA tooling and promoted by Nvidia itself.
