It's a very optimistic assumption by @polar_sh tech team that their users will be updating the api and webhooks every quarter. Never seen anything like that. Who will remind users that they need to update? Who will be keeping track on that?
After testing Opus 5.5 xhigh, I can say that it's dumber than Opus 4.8.
I think their conceptual mistake is that they are trying to improve Opus 5, but that branch is a mistake. Better come back to building on top of 4.8.
Why should I be beta tester of a paid product like Claude Code? Every fkg new update. In particular, Opus 5.5 with the Concise setting enabled still generates a lot of noise.
