TL;DR: Z.ai has released GLM-5, a 744B parameter open-weights model designed to handle complex systems engineering and long-horizon agentic tasks.
Summary: Z.ai released the GLM-5 model, which is optimized for agentic coding and complex engineering tasks. It scales to 744B total parameters (with 40B active) compared to GLM-4.5's 355B, and is pre-trained on 28.5T tokens. The model weights are open-sourced and available on Hugging Face.
Why it matters: This release offers builders a powerful new open-weights alternative for building software-engineering agents. Developers should benchmark its capabilities on long-horizon reasoning tasks and evaluate it via OpenRouter or local deployment.
