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
Nexa SDK
Nexa SDK runs text, vision, audio and image models locally across CPU, GPU and NPU backends, with a single unified API and OpenAI-compatible server.
- Runs on NPUs, not just CPU and GPU
- One API for text, vision and audio models
- OpenAI-compatible local server
Key differences
