If DS4.1 impresses you I would be really interested to see your comparison to GLM 5.3. I switched from the one to the other and even if GLM 5.3 is a bit slower I don't think I'll be going back.
DS4 (not 4.1) crossed my dont-care threshold and I genuinely stopped paying attention to new models. I'd love to try GLM 5.3 but I just don't see any point in spending the effort any more. I can get passable intelligence for a bargain price either direct from China or from a ZDR EU provider for a small markup. Paying 10x more will not make me 10x happier, it's unlikely to make me even 1.1x happier now I've got some intuition for the natural limits of these models.
I don't even bother checking how much I spent on API any more, its well under $30 over the past 2 months despite daily constant use. Who even needs a subscription at these numbers?
Wallclock time matters and GLM 5.3, even when it is considerably slower (~30 tokens right now vs 100+ on DeepSeek 4) it is quite frequently faster on the same set of tasks overall. Deepseek 4 seems to do the 'Oh, wait' thing just about forever and has a tendency to find irrelevant rabbit holes that it then spends a massive amount of tokens on.
