GLM-5: From Vibe Coding to Agentic Engineering (https://z.ai/blog/glm-5)

This is a huge new MIT-licensed model: 754B parameters and 1.51TB on Hugging Face (https://huggingface.co/zai-org/GLM-5) twice the size of GLM-4.7 (https://huggingface.co/zai-org/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 (https://twitter.com/karpathy/status/2019137879310836075) and Addy Osmani (https://addyosmani.com/blog/agentic-engineering/).

I ran my “Generate an SVG of a pelican riding a bicycle” prompt through GLM-5 via OpenRouter (https://openrouter.ai/) and got back a very good pelican on a disappointing bicycle frame (https://gist.github.com/simonw/cc4ca7815ae82562e89a9fdd99f0725d):
