Overview

Z.ai released GLM-5, a massive 754B parameter MIT-licensed language model that’s twice the size of its predecessor. The company is promoting the term “Agentic Engineering” to describe professional software development using LLMs, moving beyond casual “vibe coding” to more structured AI-assisted programming approaches.

The Breakdown

  • GLM-5 contains 754 billion parameters and weighs 1.51TB - making it twice the size of GLM-4.7’s 368B parameters
  • The model uses an MIT license - allowing unrestricted commercial and research use unlike many other large language models
  • Z.ai is advocating for “Agentic Engineering” as professional terminology for LLM-assisted software development, distinguishing it from casual “vibe coding”
  • The model demonstrates strong SVG generation capabilities - producing detailed graphics like a pelican on a bicycle when prompted
  • This represents a shift toward legitimizing AI-assisted programming as a formal engineering discipline rather than experimental tinkering
