Mojo🔥, the programming language that has been open source since May 2023, has finally delivered on its initial promise. The compiler and toolchain for Mojo have been released under the Apache 2 license today, August 18th, 2026.

However, by August 2025, the project's direction became uncertain, and it is now uncertain if Mojo will evolve into a full Python superset.
Despite this, the Mojo team remains optimistic about the progress of AI-assisted coding tools that assist in migrating Python code to Mojo, making the transition smoother in the future. Mojo now stands as its own language, tailored for GPU programming with syntax inspired by Python, but not entirely compatible with existing Python code.
