Not for profit. For the community.
Nanotune is a simple, interactive CLI for fine-tuning small language models on Apple Silicon. No YAML configs, no complex flags - just an interactive TUI that guides you through each step.
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.
Premium capabilities.
Zero paid tiers.
Apple Silicon Native
Optimized for MLX to leverage unified memory architecture, delivering blazing fast local fine-tuning on Mac.
Interactive TUI
No complex YAML configs or endless CLI flags. A clean, interactive interface guides you through every step.
End-to-End Pipeline
Automatically handles dataset validation, ChatML formatting, training loops, and LoRA fusion.
Built-In Evaluation
Validate model performance with integrated LLM judge and benchmarking suites directly from the CLI.
