GLM-5.3

Zhipu's newest flagship — the coding-agent GLM.

GLM-5.3 reuses GLM-5.2's base checkpoint and puts the entire gain into post-training: about +50% on Z.ai's own Code Bench and 4.6 -> 28.3 on Terminal-Bench 3.0. AnyModel serves it through the metered Z.ai route with a 200K window, so it is the cheap way to put a current coding flagship behind an agent.
