Company Australian-made AI is independent AI Matilda is live. MC-3 and our own cloud are next. Australia’s technology independence is no longer a pipe dream, and organisations in New Zealand, Singapore and beyond want it too. Read Company Why we’re getting right behind open weights The strategy papers your people paste into public AI services can teach someone else’s model how you think. They should be teaching yours. Read Announcements Introducing Matilda’s Open Beta: Australian AI, Built for Trust Today, we’re opening Matilda to a broader group of beta users. Matilda is available at matilda.maincode.com and on the Apple App Store. Matilda is Maincode’s Australian AI system: built from metal to model, designed for thoughtful use, and held to a higher standard for how AI should behave. We’re building Matilda because Australia should have more than access to powerful AI. We should have AI systems that understand our context, reflect our standards, run on infrastructure we can trust, and gi Read Engineering Building the machine a model actually wants A model, once you stop thinking of it as math and start thinking of it as a machine, is a dataflow. The weights stream in once and then sit still, the key and value for every token pile up and get read again by every token that follows, and the activations move from a projection into attention into a mixture of experts and back into the residual while a small sum runs between the GPUs so each one ends up holding the whole answer. Serving a model is really just moving those tensors along a path, Read

Questions about Matilda

Is Matilda free?

Matilda Chat is free on the web, iOS and Android. Paid plans start at $25 a month, include Chat and Code, and are listed on the pricing page. For the API or your own instance, talk to us.

Where does my data go?

Matilda processes and stores your conversations on MC-2, the cluster we own and run in Melbourne, and an organisation can have its own instance there or in its own data centre. The trust and security page lists each commitment and the policy it’s written in.

Where can I use it?

You can use it on the web at matilda.com, on iOS and Android, on the desktop for macOS, Windows and Linux, and in your terminal and CI with Matilda Code.

What can’t it do yet?

It can be too cautious, it can miss context, and parts of it aren’t yet as fast as we want. Tell us when it gets something wrong, because that’s the feedback we want most.

Can my organisation run its own Matilda?

Yes. We start from the open-weights model that suits your work, train it on your material and align it to your requirements, and you run it in your own instance and hold the weights. See how it works.
