Z.ai Releases GLM-5.3 Coding Model
The 750B parameter GLM-5.3 model outperforms Kimi K3 on several benchmarks while using only a third of the parameters. Z.ai will release the open weights on Hugging Face in two weeks. The jump in performance stems from scaled post-training. Developers gain a highly efficient frontier-class tool for agentic coding tasks.
