Picked Claude Opus 4.6 5 developers
Believes Opus 4.8 and Opus 5 feel worse than 4.6 after prolonged heavy use.
4.8's safety restrictions block or weaken 5-10% of tasks, making it worse than 4.6 in practice.
Finds 4.8 less useful than 4.6 for multi-turn assistant work because it over-prioritizes finishing tasks.
Opus 4.6 was better than the current 4.8 in my subjective opinion using it. I have no real reference since in Europe mythos and its sister models aren't available... So having a model of 4.6 quality is still extremely awesome. That currently is more of less the frontier reference outside the US :(
