4.7 flash is what I used.

In the thinking section it didn't really register the car and washing the car as being necessary, it solely focused on the efficiency of walking vs driving and the distance.

When most people refer to “GLM” they refer to the mainline model. The difference in scale between GLM 5 and GLM 4.7 Flash is enormous: one runs on acceptably on a phone, the other on $100k+ hardware minimum. While GLM 4.7 Flash is a gift to the local LLM crowd, it is nowhere near as capable as its bigger sibling in use cases beyond typical chat.
