llamafile
llamafile is a speech (TTS/STT) tool - Distribute and run LLMs with a single file.
Overview
llamafile lets you distribute and run LLMs with a single file.
llamafile is a Mozilla Builders project (see its announcement blog post), now revamped by Mozilla.ai.
Our goal is to make open LLMs much more accessible to both developers and end users. We're doing that by combining llama.cpp with Cosmopolitan Libc into one framework that collapses all the complexity of LLMs down to a single-file executable (called a "llamafile") that runs locally on most operating systems and CPU archiectures, with no installation.
llamafile also includes whisperfile, a single-file speech-to-text tool built on whisper.cpp and the same Cosmopolitan packaging. It supports transcription and translation of audio files across all the same platforms, with no installation required.
llamafile is open-source, written primarily in C++, with 24,689 GitHub stars under the Other license. The latest release is 0.10.3 (2026-06-02).
How it fits a local-AI stack
llamafile runs on your own hardware, so pair it with a model and a GPU sized to your needs. Use the VRAM calculator to pick a model that fits your card, and see what you can run for hardware guidance. Related speech (TTS/STT) tools in the directory:
