The Mojo language (by Modular, now Qualcomm) is now open-source

Mojo 1.0 has been released as fully open-source software under the Apache 2.0 license, making its compiler, tooling, and standard library publicly available for extension to new platforms. The Modular Platform now supports AWS Trainium, Google TPUs, Qualcomm Cloud AI 100 and Dragonfly accelerators, and native Windows support is in development through a partnership with Microsoft. Modular Cloud is publicly accessible, offering OpenAI-compatible shared endpoints and dedicated deployments for enterprise customers such as MiniMax.
