Which AI models can the Mac mini M5 Pro 48GB run?
Memory decides whether a model fits on the machine at all; bandwidth decides how fast it answers. The selected configuration has 48GB of memory and 307GB/s of bandwidth.
| Memory | Available to the model | Max model size | What it can do |
|---|---|---|---|
| 16GB | ~12GB | ~19B parameters | Small models: summarizing, drafting, trials — a handful of users |
| 24GB | ~18GB | ~28B parameters | Small models: summarizing, drafting, trials — a handful of users |
| 32GB | ~24GB | ~38B parameters | Mid-size models, internal document Q&A — small team |
| 48GB | ~36GB | ~57B parameters | Mid-size models, internal document Q&A — small team |
| 64GB | ~48GB | ~76B parameters | Larger mid-size models, the highest memory tier of Mac mini |
Estimates based on: a 4-bit quantized model takes ~0.5 bytes per parameter; macOS lets the GPU use ~75% of memory; 20% is reserved for context. These are not benchmark results — we test on real hardware for you before you commit.
Who the 48GB configuration is for
Trials and a handful of users
Up to 24GB · your 48GB configuration
Try out local AI with small models: summarizing, drafting short documents and document Q&A for a few people. A good fit when your business wants to test the waters before a larger investment.
Small team, internal document Q&A
32–48GB · your 48GB configuration
Mid-size models, longer context: a Q&A assistant over your internal document library for a small team on the same company network.
Larger mid-size models in a compact machine
From 64GB · your 48GB configuration
The highest memory tier of Mac mini: larger mid-size models and longer context. If you need larger models or many people asking at once, look at Mac Studio.
There is no fixed user count per tier: it depends on the model, prompt length and how many people ask at once. Namtech measures against your real workload before you commit to a configuration.

Mac mini M5 Pro 18/20 48GB FAQ
What size AI model can the Mac mini M5 Pro 18/20 48GB run?
About 57B parameters at 4-bit quantization. With 48GB of unified memory, about 36GB is available to the model, after leaving room for the operating system and conversation context. This is an estimate to help you choose a machine; real figures depend on the specific model, context length and number of concurrent users.
Can the Mac mini M5 Pro 48GB run a 70B model?
No, not at 4-bit quantization. The 48GB configuration holds models up to about 57B parameters. The lowest-priced Mac mini that can run 70B is the Mac mini M5 Pro 15CPU 16GPU 64GB 512GB (~76B) at 90.600.000₫ (VAT included).
How many users is the 48GB configuration suitable for?
Small team, internal document Q&A. Mid-size models, longer context: a Q&A assistant over your internal document library for a small team on the same company network. The real number of concurrent users depends on the model and prompt length, so Namtech measures on real hardware against your use case before you commit to a configuration.
How much does the Mac mini M5 Pro 18/20 48GB cost?
84.000.000₫, VAT included, with the default 512GB SSD and 2.5Gb Ethernet. Storage can be upgraded from 512GB to 8TB; 10Gb Ethernet costs an extra 3.300.000₫. The price updates instantly in the configurator at the top of the page.
Can I upgrade the RAM after purchase?
No. Mac mini memory is built into the chip, so you must choose the right amount when you order. That is why you should work out the size of the models you plan to run before you decide.
Should I choose 48GB or step up to 64GB?
Choose 48GB if the models you need to run are under about 57B parameters. The Mac mini M5 Pro 18CPU 20GPU 64GB 512GB runs up to about 76B, at 97.200.000₫ (13.200.000₫ more), VAT included. Because RAM cannot be upgraded after purchase, choose the next tier up if you are unsure.
