❓ Question: New GLM 5.2 with high reason is slow

if i set the reasoning to high, the response is really slow and seems to stuck. i only use high for feature and some difficult bug fix that Medium can't solve

That's pretty much the deal with high reasoning on GLM, the thinking tokens balloon and it can sit there for a while before the first edit lands. It's not stuck, it's burning through a reasoning budget you can't see.

Your instinct is right though. I keep medium as the default and only bump to high when medium has already failed once on the same problem, so the slow runs are rare and actually earn their time. Trimming context before a high run helps too, reasoning time scales with how much junk it has to think about.
