The common story is that a cheaper model means a cheaper bill, but the real question is what the work costs once you count retries, review, and the context you had to rebuild. In this video, I share the inside scoop on running GLM-5.3 inside the coding tools you already use: - Why the harness matters more than the model underneath it - How to launch GLM-5.3 inside Claude Code and Codex - What carries across a model switch and what does not - Where the cheap model earns the work and where it loses A cheaper model is a real lever, but only after you measure what the result you actually accepted cost you.
