Mull does its thinking on your iPhone, and it does it with open models and open software built by other people. Those are named here, with their licences.
The AI models
Built with LlamaSummaries, titles and tags are produced on your phone by Llama 3.2 3B Instruct, from Meta.
Llama 3.2 is licensed under the Llama 3.2 Community License, Copyright © Meta Platforms, Inc. All Rights Reserved.
Speech is turned into text on your phone by Whisper, from OpenAI — the multilingual small model. Whisper is released under the MIT licence, Copyright © 2022 OpenAI.
Both models are downloaded once and then live on your device. Neither one sends anything anywhere: there is no inference server behind Mull, which is the entire point of it.
The software
Mull is built on these open-source projects:
MIT licence
- WhisperKit — Argmax, Inc. Runs Whisper on Apple silicon.
- MLX Swift and MLX Swift LM — Apple. The array framework and language-model runtime that execute Llama on the phone.
- ZIPFoundation — Thomas Zoechling. Makes your backups ordinary zip files you can open anywhere.
- yyjson — Yaoyuan Guo.
- EventSource — Mattt.
Apache licence 2.0
- swift-transformers and swift-huggingface — Hugging Face. Tokenising, and fetching models to your device.
- swift-jinja — Hugging Face.
- swift-argument-parser, swift-collections, swift-numerics, swift-atomics, swift-system, swift-syntax, swift-nio, swift-crypto and swift-asn1 — Apple.
Copies of these licences are distributed with the source of each project. If you think something is missing or wrongly attributed here, please tell me and I will put it right.
