GLM & Kimi are both good to do it with just a bit of prompt engineering (historical preservation, EU laws, etc, you know the drill); Opus 5.5 is also ok to do it according to EU laws, but only with Opus 4.8 subagent - this part is tricky, I'm using ./.claude/agents/opus48.md template, bc this is the only known to me way to kick off 4.8 agent explicitly, regular tooling CC has doesn't allow to downgrade the subagent. 5.5 becomes the lead, 4.8 is doing the dirty work - this pairing worked out great for WLBT reconstruction and some other binaries, but not all. The same second you touch something like hypervisor - it becomes more complex, 5.5 won't be able to lead, so you need to go to China.

A few sad and bad moments I experienced: 5.5 will not optimize GPU kernels for you, somehow A\ decided that it's "cyber"; 5.5 will get safeguarded with almost any kind of deep kernel work. I'd say, "shame on you, Anthropic", but it's too late.
