How to read this table
One line per chip of this family and per memory size it comes with: the memory decides which models fit, the chip how fast they write.
- Strongest that runs comfortably
- The strongest model that fits comfortably there and writes at least at your reading speed, 5 tokens per second; under its name, whether it installs in one click in Twoody.
- Writes
- Its speed there, in tokens per second: an estimate from public llama.cpp benchmarks, not a measurement made with Twoody.
- Suggested by Twoody by default
- The model the app installs first on that computer, and the memory it needs there. Not always the strongest: one Twoody has measured with its memory, its tools and your documents.

The Mac mini is the least expensive way to run a local LLM on a Mac: a model of 8 billion parameters with 16 GB, a mixture of experts with 48 GB and a Pro chip.
Silent and always on, a Mac mini is also the kind of computer the iPhone and Android apps, in private beta, are made to use from afar.
The Pro versions read their memory more than twice as fast as the base chips: larger models, and faster answers.
