llamafile review

llamafile takes a different approach from every other app here: the model and the software ship as one executable file. Mozilla.ai combines llama.cpp with Cosmopolitan Libc so the same file runs on most operating systems and CPU architectures with no installation. You download a pre-built llamafile, make it executable on macOS, Linux or BSD, or add .exe on Windows, and run it. You can also run the llamafile binary with any GGUF weights you already have, and the companion whisperfile does speech-to-text and translation the same way. That makes it the easiest way to move a model onto an offline or air-gapped computer. Version 0.10 moved to a new build system that tracks recent llama.cpp releases, and the project notes it may miss some features of the classic builds, which stay available. The main limits are a basic interface and Windows refusing executables over 4GB, which rules out larger bundled models there.
