Modular open-sources Mojo and MAX; no adoption data is given

Modular co-founder Chris Lattner announces that the Mojo language and the MAX inference platform are fully open source and allowed for commercial use, with public support today for NVIDIA, AMD and Apple hardware. Modular makes an AI programming language and inference software; Qualcomm announced its acquisition of Modular in June 2026, expected to close in the second half of 2026. Mojo is Modular's language for writing high-performance AI code, and MAX is Modular's inference platform. Lattner is the principal creator of the LLVM compiler framework and the Swift language. Lattner writes that these components are "fully open - for development, extension, and commercial use" (Chris Lattner, 2026-10-23). Support for Qualcomm, Google TPU and AWS Trainium is still on the roadmap. The post gives no adoption or performance figures; the full license on Modular's site wasn't read. Our reading: open-sourcing settles the licensing question. CUDA is NVIDIA's proprietary software ecosystem. Dependence on it falls only when the same code runs on other vendors' hardware. For Qualcomm, Google TPU and AWS Trainium, that support is still on the roadmap. How we checked →

Concept illustration on a pale green background: on the left, three grey chips lettered NVIDIA, AMD and APPLE, each with an emblem beside the word, are joined by solid lines to a dark-framed central panel showing a red open padlock above two columns headed MOJO and MAX, each with a grey box of placeholder lines. On the right, a grey plate lettered ROADMAP sits above three empty dashed-outline boxes, each linked to the panel by a dashed line.
