Summary
CJ Zafir's team has introduced Mac-1, a 6.6B-parameter small model that runs locally on Mac with only 7GB of RAM. It can chain-call 487 Mac-native tools, with an inference speed of 65 tok/s, aiming to disrupt the cloud-based large model-dominated Agent paradigm.

Holy crap, this is basically stealing Apple’s thunder!
A tiny 6.6B model just shut up Siri and a bunch of cloud giants, and it runs locally on a Mac with only 7GB of RAM.
CJ Zafir and team’s Mac-1 not only has ridiculously small parameters but also hooks into 487 native Mac tools, supports chained calls, automatic reasoning, sending emails, scheduling meetings — the works. Output speed: ~65 tok/s, and the UI is pure Mac aesthetic.
Everyone used to think reliable agents required large models + the cloud, but this local little thing is about to flip the “bigger model = stronger” theory right off the table.
What makes it truly impressive is the application layer built as a native Mac experience — humans enjoy using it, while the Agent works behind the scenes.
The era of cloud SaaS agents may never really get started — it’s already being killed by the combination of a local small model + native tools.
Feels like Apple dropped the ball, and this company just picked it up and ran with it.
Finally, I need to actually test whether Chinese support is smooth.
CJ Zafir (@cjzafir): Here’s a teaser of our Mac-1 model.
6.6B model runs locally (on any Mac) requires 7GB RAM (12GB ideal) can use 487 MacOS native tools perform multi-tool chained tasks reasoning: ON output: ~65 tok/s
We built a robust application layer around the model to make
