Outlier Nano on Mac mini M1: fits comfortably. Minimum unified memory required: 6 GB. Disk size: 2.37 GB. Default context window: 32K tokens. On Mac mini M1 the Outlier Nano bandwidth-scaled estimate is ~6.1 tok/s [estimated from family-bandwidth ratio]; derivation: 71.7 tok/s on M1 Ultra × (68.25 / 800) bus ratio for the Apple M1. Treat as a first-order projection — the Outlier Nano number on this 2020 machine has not been formally measured.
The pairing under examination is Outlier Nano (2.37 GB MLX 4-bit, Qwen3.5-4B base, 32K default context, 6 GB unified memory minimum) on a Mac mini M1 (Apple M1, 8 CPU cores, 8 GPU cores, 8|16 GB unified memory, 68.25 GB/s, 2020). Outlier loads this tier as one mlx_lm process inside the bundled FastAPI sidecar. Apple Silicon decode on dense 4-bit weights is bandwidth-bound, so the ceiling on this exact Mac mini M1 scales as the ratio 68.25 / 800 = 0.09× the published M1 Ultra number.
The Mac mini M1 is a desktop with active cooling, which is the configuration that comes closest to holding the figure above through a sustained back-and-forth session. There is no battery to trade against and no lap to keep cool, so the limit on Outlier Nano here is the 68.25 GB/s memory bus rather than the thermal envelope. This is the shape of machine to pick if the job runs unattended.
Outlier’s Outlier Nano has a measured peak generation footprint of about 3 GB. The rule of thumb is to leave roughly 4 GB for the OS and one open browser tab, so across the Mac mini M1 memory options that leaves 8 GB → 1.0 GB free; 16 GB → 9.0 GB free. On Mac mini M1 the Outlier Nano bandwidth-scaled estimate is ~6.1 tok/s [estimated from family-bandwidth ratio]; derivation: 71.7 tok/s on M1 Ultra × (68.25 / 800) bus ratio for the Apple M1. Treat as a first-order projection — the Outlier Nano number on this 2020 machine has not been formally measured.
The 2020 Mac mini M1 ships with 8|16 GB of unified memory, so headroom for the 6 GB Outlier Nano requirement is 2 GB on the base SKU. Step-by-step install instructions live on the install guide; the part that varies for this Apple M1 machine is that the 2.37 GB pull from Outlier-Ai/Outlier-Nano-4B-MLX-4bit over HTTPS lands in ~/Library/Application Support/Outlier/models/nano/ and download time is bandwidth-limited by the network, not by the 8-core Apple M1 CPU.
The Outlier Nano tier defaults to 32K context and caps at 256K. KV cache scales linearly with context length on dense models, so longer contexts trade headroom for capacity. On a 8|16 GB Mac mini M1, the default context is the safe starting point.
2.37 GB on disk against 8|16 GB unified memory means the weights alone consume about 30% of the base SKU’s RAM on the Mac mini M1.
For heavier work, the Lite tier is the next step up; check that the 8|16 GB SKU you have can fit its weights before installing. The unified-memory explainer works the bandwidth math out, and the bandwidth ratio for Mac mini M1 is 0.09× M1 Ultra reference.
