Summary


GLM-5: From Vibe Coding to Agentic Engineering


This is a huge new MIT-licensed model: 754B parameters and 1.51TB on Hugging Face twice the size of GLM-4.7 which was 368B and 717GB (4.5 and 4.6 were around that size too).


It's interesting to see Z.ai take a position on what we should call professional software engineers building with LLMs - I've seen "Agentic Engineering" show up in a few other places recently. most notable from Andrej Karpathy and Addy Osmani.


I ran my "Generate an SVG of a pelican riding a bicycle" prompt through GLM-5 via OpenRouter and got back a very good pelican on a disappointing bicycle frame:


The pelican is good and has a well defined beak. The bicycle frame is a wonky red triangle. Nice sun and motion lines.

How to Use in Your Ecosystem

GLM-5 could significantly enhance the Claude-powered orchestrator's code generation and agent reliability capabilities across Zac's Rails ecosystem. For infrastructure apps like task_tracker and app_monitor, the model could generate more sophisticated test cases and refactor existing code with greater contextual understanding. The agentic engineering framework aligns perfectly with the ecosystem's focus on automated testing and code quality, potentially improving prompt engineering and tool use across prediction market and game applications.
