And? They aren't as good as SOTA models. Even the SOTA model provider's small models aren't worth using for many of my coding tasks.

In my limited experience with it, GLM 5.1 is on par with Opus 4.6.

I used GLM5 quite a bit, and I'd say it was maybe on par with Sonnet for most simple to medium tasks. Definitely not Opus though. Didn't test super long context tasks, and that's where I would expect it to break down. A recent study on software maintainability still showed Sonnet and Opus were peerless on that metric, although GLM series of models has been making impressive gains.
