GLM-5.2 is the new leading open weights model on Artificial Analysis

I have been trying out GLM 5.2 and I am really impressed by it for the most part.

To all people on Hackernews, I am curious as to what agent harness are you using it with.

Previously I was using opencode and then I switched to using Opencode + obra/superpowers and creating custom skill.md themselves for it. I found things to take more time and intervene more but the result of it has been that I have found it to work better.

Now I have also started using oh-my-pi as well and I found it to be faster compared to Opencode.

I am unsure how much of there is a difference to it and how much of things are placebo but what is your opinion regarding the best Agent harness for GLM 5.2?

Ok, it is nice to see another great open source model. Not sure what to think of all these benchmarks but GLM was already quite strong before so an update is very welcome.

I tried it today through Openrouter and the API is atrocious. I got multiple rate limit and random errors every turn.

Somebody wrote [1]; "I am never touching Minimax or GLM again. Their APIs had constant outages and I had to restart my runs multiple times — after burning money on the runs that failed midway." and I 100% agree.

The model might be good, but if the API is so bad, it's effectively useless.
