Z.ai launches GLM-5.2, a coding agent trained on SGLang and Slime that reportedly matches Claude Opus capabilities

Really likes how @Zai_org keeps pushing the frontier of intelligence and infra. They quietly open-sourced GLM 5.2 with coding agent capability at latest Opus level. People were worried about open source being far behind closed source, but GLM 5.2 proves it wrong! Infra side, @slime_framework has been the de facto open source RL framework for most of the large-scale RL workload (we have Miles built on top of slime too).

Huge respect to @jietang @Zai_org 🫡🫡🫡
