Can't speak for browser demos, but I just got the ternary model working on my M5 generating images. The 1 bit didn't work, as it has a known bug with XCode 24.5 and I wasn't in the mood for installing 24.4 alongside.
The online demos require WebGPU so Firefox on mobilr and privacy enhanced browsers will break. WebGPU support on Linux and other open source systems is also trash, you can force it to work in Chrome but it won't be happy.
