1) i use my brother's claude pro subscription. if i needed to, i would use openrouter + API if i didn't have his subscription, but i don't think i really need it. i've never purchased an ai subscription myself, nor paid my brother for his. i would never use frontier us models for anything serious on openrouter + API

2) yes, when claude starts getting too preachy and the task at hand is important to me i use openrouter + api + chinese models. my computer can't even run qwen 3.8 27b.

3) i use claude code because i think using other ones isn't allowed. i don't really like it, and generally prefer opencode (i've had to use it to do some things for my brother). i'll try using other ones though

4) no, and i didn't actually know they existed. opencode and claude code's agentic things are enough for me, though i don't do actually complex projects

5) no, i won't use them unless i get good local inference going (i.e. never).
