Mojo 🔥 — the programming language for all AI developers.

Mojo combines the usability of Python with the performance of C, unlocking unparalleled programmability of AI hardware and extensibility of AI models.

Mojo is a new programming language that bridges the gap between research and production by combining the best of Python syntax with systems programming and metaprogramming.

With Mojo, you can write portable code that’s faster than C and seamlessly inter-op with the Python ecosystem.

Available on Mac 🍎, Linux, and Windows (WSL)

The Next Big Step in Mojo🔥 Open Source

March 28, 2024

At Modular, open source is ingrained in our DNA. We firmly believe for Mojo to reach its full potential, it must be open source. We have been progressively open-sourcing more of Mojo and parts of the MAX platform, and today we’re thrilled to announce the release of the core modules from the Mojo standard library under the Apache 2 license!

We have always believed that building Mojo in the open will lead to a better result, because it allows its design to be shaped by the feedback from the broader community. We released Mojo very early and have been driving steady improvements since May of 2023 (see the changelog). Building a language and its infrastructure is hard work and takes time, and we’re excited to move from sharing our work to collaborating with Mojo developers worldwide.
