Nanotune

A simple, interactive CLI for fine-tuning small language models on Apple Silicon — built by the Nano Collective, a community collective building AI tooling not for profit, but for the community. Everything we build is open, transparent, and driven by the people who use it.

No YAML configs, no complex flags — just an interactive TUI that guides you through each step. Nanotune handles the MLX and llama.cpp tooling for you automatically.

Quick Start

npm install -g @nanocollective/nanotune
nanotune init
nanotune data add
nanotune train
nanotune export
nanotune chat        # talk to your fine-tuned model
