Summary

The creator shares Z.ai's blog post "Scaling Pain" about debugging GLM-5 at scale. It covers the problems Z.ai hit when serving a model to coding agents in production and is a real-world case study in LLM serving.

Key points

• Z.ai published lessons from debugging GLM-5 when serving it at scale.
• Coding-agent traffic creates its own serving problems at scale (the article's focus).
• It's a useful real-world case study for LLM serving and inference infrastructure.
