That is opposite to my experience so far, can you describe your coding tasks? Mine are systems level code, utilities, operating system code, networking and real time control stuff.

I also prefer GLM-5.3-flash to DS-4.1-flash, but it's close. Since Z.ai has been offering essentially free GLM-5.3-flash tokens on their coding plan between 8am-6pm pdt I've been using it a lot... though that ends on Oct 10 IIRC.
