Even when they're reaching parity with American models, Z.ai, Qwen and Deepseek are upholding their end of the bargain. I'd criticize them too, if they were due any scrutiny.
I use GLM 5.2 daily. Calling it Opus tier is a bit of a misnomer. It is maybe comparable to Sonnet 5, definitely not Opus 4.8.
It is a great model for the price, but it has much worse autonomy and long context performance, and I don't trust it for anything beyond personal projects, whereas I use Opus/Fable and GPT for work.
