At 14 Justine Tunney published software. Now she makes AI models run from a file

Justine Tunney, who began publishing software at 14 and later worked at Google on TensorBoard, created Cosmopolitan Libc, a five-year project enabling a single binary to run natively across Linux, Windows and macOS. In 2023 she combined Cosmopolitan with llama.cpp to create llamafile, which packages an AI model and the software needed to run it into a single executable file, announced by Mozilla's innovation group in November 2023. Her other projects include the single-file web server redbean and tools such as blink and sectorlisp.
