How it works
01 — Discover
ZMatrix recommends models made for your Mac and tells you up front how each one will run: smoothly, slowly, or not at all.

02 — Shrink
Create several compact versions at once. ZMatrix compares them for you and recommends the smallest one that still answers well.

03 — Customise
See where a habit like refusing to help lives inside the model, then decide what to change. You stay in control of every edit.

04 — Understand
Watch what the model is thinking at every step on its way to an answer, in views that explain themselves as you go.

05 — Compare
Test how fast and how good each version is, compare answers side by side without knowing which is which, and keep every result.

06 — Chat
Chat with any version you've made, with pictures, voice and a live view of its speed and memory.

See the difference
Original
Approximate sizes for a model with 8 billion parameters. Each square stands for one of the model's numbers. Smaller files use fewer shades, and the red square marks the biggest change.
Smart about memory
ZMatrix checks your Mac's memory before it loads anything. If a model is too big, it tells you why and finds a way that works, instead of slowing your Mac to a crawl.
$ zmatrix fit ~/Models/Qwen3-8B 8192 chat Rung Verdict Peak As asked will_not_fit 17.87 GiB K/V cache 8-bit will_not_fit 16.23 GiB Stream every block from disk (K/V cache FP32, 8192 tokens) will_not_fit 5.65 GiB Stream every block from disk (K/V cache 8-bit, 8192 tokens) will_not_fit 4.01 GiB Nothing fits, even with the weights streamed from disk. # From the report's notes and suggestions: Predicted peak 17.87 GiB exceeds the 2.23 GiB available. Use 4-bit weights: saves 10.97 GiB, peak 6.90 GiB.
Real output: on a busy Mac with little memory free, ZMatrix explains what won't fit and suggests what will, without loading a thing.
Our promises
Every change creates a new version, and copies take almost no extra space. Go back, try another idea, or compare any two.
Every model you make remembers exactly how it was made, so you can repeat it, explain it, or share it with confidence.
Built for Apple silicon from the ground up. No web page in disguise and nothing extra to install. A true Mac app.
Your models and conversations stay on your Mac. It only goes online to download models, check for updates, or use services you add yourself.
ZMatrix AI Companion for iPhone and Android
