Zet: an open-source layer on Laya that knows when to ask a human

Confidence scores aren't error rates. Zet sits on top of Laya and marks every answer sure or unsure, using conformal prediction sets and a Learn-then-Test threshold calibrated per language, so the answers it automates stay within an error budget you choose (say 5%). On MASSIVE (human-labeled, 300 examples per language, 5% budget), it automated 84% of English and 80% of Swedish requests on a 6-scenario task, with 0 errors in 75 sure English answers. When the task got harder (18 scenarios), it automated nothing, while its prediction sets still contained the right answer 97-99% of the time. That refusal is the feature working. Runs locally on ONNX Runtime with no PyTorch, with a web interface for creating tasks, uploading labeled examples, calibrating, and reviewing unsure answers. Apache-2.0, built on Laya (not endorsed by its authors).

I built an interactive 3D PC anatomy tool to learn what’s actually inside a computer

I’ve been working on an open-source project called PC Anatomy.

The idea is simple: instead of reading a wall of text about PC components, you can explore a PC visually in 3D, click on the different parts, and learn what each component does.

I wanted it to feel more like taking apart a computer than reading a hardware guide.

It’s still something I’m actively improving, so feedback, feature ideas, issues and contributions are very welcome.

If you find it useful or just like the idea, a star on GitHub would be appreciated - it helps more people find the project.

I’d also genuinely love to see someone fork it, build on top of it, add new hardware, improve the visuals, or take the idea in a direction I haven’t thought of.

If you try it, let me know what you think is missing.
