Overview

Z.ai has released GLM-5, a massive 754B parameter MIT-licensed language model that’s twice the size of its predecessor. The post also introduces “Agentic Engineering” as a term for professional software development using LLMs, moving beyond casual “vibe coding” to structured AI-assisted programming practices.

The Breakdown

  • GLM-5 is a 754B parameter open-source model - at 1.51TB it’s twice the size of GLM-4.7 and represents a significant scale-up in accessible AI models
  • The model demonstrates strong SVG generation capabilities - it produced a detailed pelican graphic from a text prompt, though with some limitations in bicycle geometry
  • Z.ai is promoting “Agentic Engineering” as professional terminology for LLM-assisted software development, distinguishing it from casual “vibe coding”
  • The MIT licensing makes this massive model freely available for commercial and research use, unlike many comparable large-scale models
