I mostly use claude code on mobile and desktop with remote sessions and do most of my coding on the go now.

I have been tempted to distill something like GLM 5.2 into a smaller html + css only model for super fast interactive UI editing, because right now it's really annoying to do with large slow models. I'm sure it would be doable to do the same for individual language / frameworks, including potentially doing a final few steps on your own code base with some LoRAs that could be kept up to date to avoid having the model have to explore the code base each time.

Doing UI work with composer 2.5 and live reload is a way different experience than slogging through it with opus 4.8
