Ustad 1.1.0

Ustad 1.1.0 for Windows 10 and 11 (64-bit).

One file. Download Ustad-Setup-1.1.0.exe (364 MB), open it and follow the steps. During setup it downloads the teacher in parts (3–4.5 GB, with checks and automatic retries); after that, Ustad works fully offline.

What's new

• 9 books: mathematics, physics and biology for grades 10, 11 and 12.
• Two teachers, chosen by the computer's memory (you can change the choice during setup):
  • Large (Gemma 4 E4B) for computers with about 12 GB of memory or more.
  • Standard (Gemma 4 E2B) for computers with 8 GB.
• The teacher can make up a new problem and solve it, quiz you, and check your answer, and remembers much more of the conversation (32K context).
• Runs on NVIDIA, AMD and Intel Arc graphics cards (Vulkan), and on the processor alone on laptops without one.
• Ustad is now open source: MIT license for the code, CC BY 4.0 for the learning content.

Installing on a computer without internet: download the teacher files from the large or standard teacher release, put all of them in the same folder as the setup (for example on a USB drive), and run the setup from there. Silent install: Ustad-Setup-1.1.0.exe /VERYSILENT /TEACHER=large (or standard).

Windows warning: the setup is not code-signed yet, so Windows may say it protected your PC. Choose "More info", then "Run anyway". Check the file against SHA256SUMS-windows-1.1.0.txt if you want to be sure it is the original.
