Opus 5.5 (O5.5) has been exceptional for me in Claude Code over the last six days. Architecture-first, DRY/SOLID coding out of the box, exceptional communication style, phenomenal token efficiency. I’ve been working with it basically nonstop, ~12 hours a day, since last Wednesday. But right around the time my monthly limit reset this evening, I noticed an extreme shift in communication style and coding behavior that feels suspiciously like Opus 5 (O5). For the last week, O5.5 would take my requirements and immediately get to work, usually knocking out a feature in minutes and doing an incredible job across implementation, UX, architecture, and token efficiency. Tonight, I’m seeing something very different.

Where O5.5 consistently respected DRY principles and the existing architecture, the modules created tonight are suddenly happy to reinvent every wheel that came before them. The difference in ability is not subtle. The other tell is token usage. O5.5 has been startlingly efficient compared with O5, which was an absolute token-eating monster. I’ve been getting substantially more feature work done with O5.5 at a fraction of the token usage. Tonight, simple tasks and relatively small features are suddenly devouring tokens at a pace that feels much more like O5. I’m especially sensitive to this because I have to request an increase in my spend limit every time I hit it. On O5, I was sending a request almost every day. On O5.5, I hadn’t needed to send a single one all week. Then tonight I jumped from roughly 70% to 90% usage in about an hour.
