Hmm, Claude Code and Opencode work fine for me.
It's a bit amusing that coding agents rely on drawing 1000W+ and using 2TB+ of memory in a datacenter to run, yet people really focus on the last few watts and few hundred megabytes of memory on their laptop (which get dwarfed by the energy cost of compiling their code anyways). But I suppose making them a bit faster and lighter wouldn't hurt.
