What each one is
llamafile
llamafile from Mozilla packs a model and llama.cpp into a single portable executable: download one file, run it, and get a local chat UI plus an OpenAI-compatible API.
- Absolute simplest distribution: one file, six OSes
- Built-in web chat UI and OpenAI-compatible endpoint
- No dependencies, no installer, no Docker required
exo
exo turns the devices you already own — Macs, PCs, phones — into a self-organizing AI cluster, splitting large models across them with automatic peer discovery.
- Aggregates the memory of all your devices automatically
- ChatGPT-compatible API on your own cluster
- No expensive GPU server needed for large models

Their licenses differ (Apache-2.0 vs GPL-3.0), which matters if you ship a commercial product. llamafile leans more beginner-friendly, whereas exo is more suited to intermediate users. In short, llamafile fits sharing a model that runs anywhere with zero install, and exo fits running models too large for any single machine at home.
